UpdateOnPostBack property of AXForm

meysun — Mon, 07 Dec 2009 23:49:00 GMT

If you need to read the values that the user entered in a text box before the record is committed to filter the possible values for the second text box then first you should set the autopostback property of the AxBoundField to true. Also you need to set the UpdateonPostback property of the AXForm.

UpdateonPostback property is set if the record cursor needs to be updated when post back happens, so that other controls could read the change. You could then use the row.GetFieldValue("FieldName") to get the value that that user entered in the text box.

How to set focus on the asp.net textbox in AxPopup form?

meysun — Wed, 21 Oct 2009 22:31:00 GMT

To set the focus include this method in your page that is opened in the popup window and call the method without control name in the page load event.

For example to set the focus on txtCustAccount

protected void Page_Load(object sender, EventArgs e)

{

SetFocus(txtCustAccount);

}

public static void SetFocus(Control control)

{

StringBuilder sb = new StringBuilder();

sb.Append("<script language='JavaScript'>");

sb.Append("function SetFocus(){document.");

Control p = control.Parent;

while (!(p is System.Web.UI.HtmlControls.HtmlForm)) p = p.Parent;

sb.Append(p.ClientID);

sb.Append("['");

sb.Append(control.UniqueID);

sb.Append("'].focus();}");

sb.Append("window.onload = SetFocus;</script>\r\n");

control.Page.RegisterClientScriptBlock("SetFocus", sb.ToString());

}

AxPopup Controls in EP

meysun — Tue, 22 Sep 2009 03:10:00 GMT

AxPopup Controls

AxPopup controls are used to open a page in a popup browser window and upon closing a popup page, pass data from the popup page back to the parent page and trigger an OnPopupClosed server event on the parent. This functionality is encapsulated in two controls - AxPopupParentControl to be used in the parent page and AxPopupChildControl to be used on the popup page. They both derive from AxPopupBaseControl. These controls are AJAX-compatible, so they can be created conditionally as part of a partial update.

Data can be passed from the popup page back to the parent page using AxPopupField objects. They are exposed via the Fields property of the AxPopupBaseControl, from which both AxPopupParentControl and AxPopupChildControl are derived.

AxPopupParentControl and AxPopupChildControl have fields with the same names. When the popup page closes, the value of each field of the AxPopupChildControl is assigned (via client-side script) to the correspondent field in the AxPopupParentControl.

AxPopupField can optionally be associated with another control, such as TextBox or any other control, by assigning its TargetId property to the ID property of the target control. This is useful, for instance, when the popup page has a TextBox control. In order to pass the user input to the parent page upon closing the popup, and to do it entirely on the client hence avoiding the round trip, a field needs to be associated with the TextBox control.

In AX 2009 this approach is used in number of places and one such control is the Business Relations list.

The AxPopupField control is placed in the user control displaying the list. In the code behind, the toolbar action calls the popup using the GetOpenPopUpEventReference method. Both the parent control and the childcontrol uses the field with the same name hiddenCustomerAccountNo to pass the values back& forth. The childcontrol gets the value from the text box using the TargetControlID.

smmBusRelListGrid.ascx

List containing the ParentControl from the popup

<dynamics:AxPopupParentControl ID="PopupConvertCustomer" runat="server" PopupHeight ="180" PopupWidth="400" >

<dynamics:AxPopupField name="hiddenCustomerAccountNo" />

</dynamics:AxPopupParentControl>

smmBusRelListGrid.ascx.cs

Code behind opening up the popup using GetOpenPopUpEventReference

protected void AddCustomerAccountNoScript(SetMenuItemPropertiesEventArgs e, string custAccount)

{

AxUrlMenuItem menuItem = new AxUrlMenuItem(CUSTOMER_ACCOUNT_DIALOG);

DataSetViewRow row = this.GetCurrentDataSetViewRow();

if (row != null)

{

AxTableContext context = AxTableContext.Create

(row.GetTableDataKey(row.DataSetView.Metadata.RootDataSource, null));

menuItem.MenuItemContext = context;

//Adding the CustAccount QueryString variable

if (custAccount != string.Empty)

{

menuItem.ExtraParams.Add("CustAccount", custAccount);

}

menuItem.RemoveNavigation = true;

//Calling the javascript function to set the properties of opening the customer account

//on clicking the menu items.

e.MenuItem.ClientOnClickScript = this.PopupConvertCustomer.GetOpenPopupEventReference(menuItem);

}

CustomerAccountDialog.ascx

The popup form transferring the value entered in the target to the parent control by using the same control name.

<div>

</td>

</tr>

</table>

</div>

CustomerAccountDialog.ascx.cs

Pop up closed after validing the data entered in the popup , giving control back to the parent page.

Redirecting in EP user control to download a file

meysun — Fri, 11 Sep 2009 06:52:00 GMT

If you have a webpage to generate files such as word doc or pdf and you need to invoke them in a button click event of an user control used in EP and allow the user to download the file through the browser. generally you would think of calling response.redirect function. This function redirects to the download page and since it sets the mime type as the respective file, it prompts the user to save the file to the local machine or open it using the right application. Since AX usercontrols inherently uses AJAX postbacks, the postback progressbar will continue to display "Loading Information" even after the file is downloaded when response.redirect is used. This is because response.redirect supposed to replace the current page displayed in the browser, but in this case it actually streams file and does not replace the currently rendered page in the browser. For such scenarios, instead of using response.redirect, you could execute a client side javascript to push the generated file in a new browser window and avoid the above issue.

protected void Button1_Click(object sender, EventArgs e)

{

AxUrlMenuItem menuItem = new AxUrlMenuItem("EPDocuGet");

DataSetViewRow row = dsEPCustInvoiceJournalInfo.GetDataSet().DataSetViews[0].GetCurrent();

AxTableContext context = AxTableContext.Create(row.GetDefaultTableDataKey(row.DataSetView.Metadata.RootDataSource));

menuItem.MenuItemContext = context;

//Response.Redirect(menuItem.Url.ToString());

string downloadURL = "window.open('" + menuItem.Url.ToString() + "', '_blank', '' );";

ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", downloadURL, true);

}

Persisting Filter conditions in EP Grid

meysun — Sat, 29 Aug 2009 02:45:00 GMT

Persisting Filter condition in EP Grid

In AX 2009, EP grid control comes with an advanced filter. Here is a code to persist the filter condition the user last entered in a page for that user, so that later when the user comes back to the same page the last filter is applied and user didn’t have to reenter then.

This code sample assumes a dataset with the name “EPSalesTableList” which contains the datasource “SalesTable”

(1) First override the pack method of the dataset ( EPSalesTableList in this example) in AOT

public container pack()
{

container ret;
SysLastValue sysLastValue;

formdatasource filterDataSource;
;

filterDataSource = SalesTable_ds; // Put your datasource name

    ttsbegin;
       // Delete last saved query for the current dataset
    delete_from sysLastValue
        where sysLastValue.Company      == curext()
           && sysLastValue.UserId       == curuserid()
           && sysLastValue.RecordType   == UtilElementType::DataSet
           && sysLastValue.ElementName == filterDataSource.name()
           && sysLastValue.DesignName   == filterDataSource.name();

    // If there is a new queryRun() object then serialize and save it
    // in the sys last value table
    // Put your datasource name

    if (filterDataSource.queryRun())
   {

        sysLastValue.RecId = 0;
        sysLastValue.Company      = curext();
        sysLastValue.UserId       = curuserid();
        sysLastValue.RecordType   = UtilElementType::DataSet;
        sysLastValue.ElementName = filterDataSource.name();
        sysLastValue.DesignName   = filterDataSource.name();
        sysLastValue.value = SysQuery::packRangeAndSortorder(filterDataSource.queryRun().query());
        sysLastValue.insert();
    }
    ttscommit;

ret = super();

return ret;

}

(2) Second override the init method of the datasource ( SalesTable in this example) within that dataset in AOT

public void init()
{
SysLastValue    sysLastValue;
    Query savedQuery;
    ;
    super();

// get the last value from the sys last value table
    select firstonly sysLastValue
        where sysLastValue.Company      == curext()
           && sysLastValue.UserId       == curuserid()
           && sysLastValue.RecordType   == UtilElementType::DataSet
           && sysLastValue.ElementName == this.name()
           && sysLastValue.DesignName   == this.name();

    if (sysLastValue && sysLastValue.Value)
    {
              // If there is an unpack error delete the saved query

if (!SysQuery::unpackRangeAndSortorder(this.query(), sysLastValue.value))
{

            ttsbegin;
            delete_from sysLastValue
                where sysLastValue.Company      == curext()
                   && sysLastValue.UserId       == curuserid()
                   && sysLastValue.RecordType   == UtilElementType::DataSet
                   && sysLastValue.ElementName == this.name()
                   && sysLastValue.DesignName   == this.name();
            ttscommit;
        }

}

}

Make sure you replace the datasourcename variable filterDataSource in the pack method with your datasource name.Save the changes, refresh AOD and now go to the page that is using this dataset and enter some filter condition & apply. Close the browser and reopen the page. Now you should see that the filter that you last applied before the browser was closed is still applied in this page.

Arif Kureshy, who is the dev manager for EP came out with this code snippet. So thanks to him for providing this sample code.

X++ based Web User Interface is discontinued in the next version of Microsoft Dynamics AX Enterprise Portal

meysun — Thu, 20 Aug 2009 02:23:00 GMT

During AX 2009, we introduced ASP.net based EP framework which brings in tons of value such AJAX out of the box, rich and responsive controls, power of .net etc. We kept the old X++ Web framework in the product for one release to help the partners and customers migrate to the new framework. Now we have published the discontinuation notice in customer source / partner source. In the next version of AX, only asp.net based web user interface will be shipped.

Custom Bound Fields in FieldGroup

meysun — Thu, 28 May 2009 04:35:00 GMT

You could make the AxBoundFieldGroup use the CustomBoundField (http://blogs.msdn.com/solutions/archive/2009/04/20/ax-custom-bound-fields.aspx) instead of the regular bound field by hooking into the OnCreatingBoundField event (KB971547) of the AxBoundFieldFactory.

For example create an assembly with the below code and put it in GAC.

public class AxSampleBoundFieldFactory
{
public void OnCreatingBoundField(object sender, CreatingBoundFieldEventArgs eventArgs)
{
if (eventArgs.Field.Name == "Date")
eventArgs.BoundField = new AxSampleDateBoundField();
}
}

Then modify the master page (C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\DynamicsAxEnterprisePortal\defaultax.master) and add the below code to invoke this eventhandler in page init. Now any page that displays a fieldgroup will use the AxSampleDateBoundField for any field with the name "Date". You can add any logic that you want here for example you may want to use other field meta data properties instead of the name.

private AxSampleBoundFieldFactory customBoundFieldFactory;

    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);

        // Subscribe to the bound field factory event
        this.customBoundFieldFactory = new AxSampleBoundFieldFactory();
        AxBoundFieldFactory.Instance.CreatingBoundField += this.customBoundFieldFactory.OnCreatingBoundField;
    }

    protected override void OnUnload(EventArgs e)
    {
        // Unsubscribe to the bound field factory event
        AxBoundFieldFactory.Instance.CreatingBoundField -= this.customBoundFieldFactory.OnCreatingBoundField;

        base.OnUnload(e);
    }

Inside Microsoft Dynamics AX 2009 book RTM'ed

http://blogs.msdn.com/microsoft_press/archive/2009/05/20/rtm-d-today-inside-microsoft-dynamics-ax-2009.aspx

I wrote two chapters in Inside Dynamics AX 2009 book about Enterprise Portal and Role Centers. I also contributed to the Architecture Chapter and upgrade. Thanks to the entire EP team who implemented these great features and contributed in many ways to the content of these chapters. These chapters have wealth of info for developers and I would recommend strongly for EP / Role Center developers :) :) .

Passing parameters from Managed code to X++ in dataset

meysun — Fri, 15 May 2009 02:13:00 GMT

In the user control code behing add an event handler to the CreatingDataSetRun event on the AxDataSource control

protected void Page_Init(object sender, EventArgs e)
{
this.AxDataSource1.CreatingDataSetRun += new EventHandler<CreatingDataSetRunEventArgs>(AxDataSource1_CreatingDataSetRun);
}

Set the param value to the event arugments

void AxDataSource1_CreatingDataSetRun(object sender, CreatingDataSetRunEventArgs e)

{

e.DataSetRunArgs.parm = "4000";

}

In AOT override or add method in the data set and use element.args().parm() to received the paramter

public void executeQuery()
{

QueryBuildRange             custRange;
;
        custRange = SysQuery::findOrCreateRange(this.query().dataSourceNo(1), fieldnum(CustTable, AccountNum));
        custRange.value(element.args().parm());
   super();

}

You can also pass an Enum. For example

void AxDataSource1_CreatingDataSetRun(object sender, CreatingDataSetRunEventArgs e)
{
e.DataSetRunArgs.parmEnumType = EnumMetadata.EnumNum(this.AxSession, "EPFormAction");
e.DataSetRunArgs.parmEnum(2);
}

public void init()
{
super();

     if (element.args().parmEnumType() == enumnum(EPFormAction) && element.args().parmEnum() == EPFormAction::CreateMode)
    {
        //do somethign here

}
}

AX Custom bound fields

meysun — Mon, 20 Apr 2009 20:28:00 GMT

A new code sample demonstrating the flexibility to customize the boundfields in Microsoft Dynamics AX 2009 EP is released in http://code.msdn.microsoft.com/axcodesamples. Here is the link directly to the sample download file. To try out these samples, download this zip file and follow the instructions given in readme.txt file http://code.msdn.microsoft.com/Project/Download/FileDownload.aspx?ProjectName=axcodesamples&DownloadId=5497

EP comes with a rich set of bound fields. This code sample demonstrates how to extend and add bound fields in EP for specific user interface requirements. This sample contains three types of bound fields:

Multi-line text
Day/month/year dropdown
Foreign key lookup that displays a description instead of an ID

Data binding provides an easy and powerful way to create a read/write link between controls on a Web page and the data in an application. With ASP.NET data binding, you can bind any server control to an AxDataSource control in EP and read and write data from Microsoft Dynamics AX seamlessly with little or no server code.

NOTE : These are code samples are not intended for production use as is. You should use them as samples and build your own solutions and test it before using it in production system. These sample bound fields do not work with BoundField designer in VS. You should work in the markup directly to use these boundfields or make the code deal with the boundfield designer.

Always keep the Filter section expanded in AxGridView

During AxUG Webinar, I got a question around how to keep the filter section always expanded in a gridview in Microsoft Dynamics AX 2009 EP. Unfortunately we don't have a simple property to do that in the AxGridView control. Since it's all ASP.NET and javascript, I mentioned that there should be an easy workaround available.
If you add the below javascript code to your user control at the bottom of the markup file ( .ascx file) then the filter section will always be in expanded mode both during initial load as well as during subsequent postbacks. Since the below code uses lot's of internals such as ids and stylesheet names, it is not guaranteed to work in subsequent releases of EP. But if you need this capability in Ax 2009 and specific pages, this may be useful.

function ExpandFilter(sender, args) {

var elem = document.getElementById('div_<%=this.AxGridView1.FilterControl.ClientID%>');

var parentDiv = elem.parentNode;

var filterArea = DynamicsFilter.GetFilterArea(elem);

if (DynamicsCommon.IsNull(filterArea)) return;

elem.style.display = '';

var applylink = DynamicsCommon.FindInstance(parentDiv, "applyfilter");

var resetlink = DynamicsCommon.FindInstance(parentDiv, "resetfilter");

var editfilterlink = DynamicsCommon.FindInstance(parentDiv, "editfilter");

if (!DynamicsCommon.IsNull(applylink) && !DynamicsCommon.IsNull(resetlink) && !DynamicsCommon.IsNull(editfilterlink)) {

editfilterlink.style.display = 'none';

applylink.style.display = '';

resetlink.style.display = '';

}

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(ExpandFilter);

ExpandFilter();

</script>

How to use Chart Control in EP 2009?

meysun — Thu, 02 Apr 2009 02:50:00 GMT

ASP.NET Chart Control

(1) Install the components

Chart Controls for .NET Framework

Chart Controls Add-on for Visual Studio 2008

(2) MODIFY WEB.CONFIG

Add the below as the child node to <HttpHandlers> section

Add the just after </system.web>

Add the just before </pages>

</controls>

(3) Create c:\TempImageFiles folder and give read access to the app pool

Here is a sample markup for user control using Chart control ( replace the highlighted ones with your datasource control and the field or display field name)

<asp:Chart ID="Chart1" runat="server" DataMember="CustTable_Current"

DataSourceID="AxDataSource1">

<asp:Legend Alignment="Center" Docking="Bottom" LegendStyle="Row"

Name="Legend1">

</asp:Legend>

</Legends>

<asp:Series Legend="Legend1" Name="Open Sales Orders"

YValueMembers="openSalesOrders**" YValuesPerPoint="4">

</asp:Series>

<asp:Series ChartArea="ChartArea1" Legend="Legend1" Name="Total Sales Orders"

YValueMembers="NoSalesOrders**" YValuesPerPoint="4">

</asp:Series>

</series>

<asp:ChartArea Name="ChartArea1">

</asp:ChartArea>

</chartareas>

</asp:Chart>
