Does the newLayoutContainer's control collection act as a stack or a queue? It seems to me that the line

ListView1.Controls.RemoveAt(0);

would remove your layoutTemplate when you load the ItemTemplate.

???

Hi Jordan. The LayoutTemplate acts as a container so items become children of the LayoutTemplate.

I guess this applies to template classes as well and so

namespace PresentationLayer

{

public class LayoutTemplate : ITemplate

{

LiteralControl table = new LiteralControl("<table><tbody><asp:PlaceHolder runat=\"server\" ID=\"ctl01$itemPlaceholder\" /></tbody></table>");

container.Controls.Add(table);

}

will also say that itemPlaceholder cannot be found cause it changed.

And i am afraid this solution is impossible when using direct databinding without a datasource

Wuz - I have it working with databinding with no DataSource. My databinding code looks like this:

XDocument xdoc = XDocument.Load(Server.MapPath("~/XmlFile.xml"));

var query = from x in xdoc.Descendants("book")

select new { id = (string)x.Attribute("id")};

ListView1.DataSource = query;

ListView1.DataBind();

Hello mike,

Thanks your entry really seems to be the only help for this topic. Unfortunately when I am using your suggestion it works for the first time when i am accessing the page, but not after the postback.

There seems to be a problem in Begin Loadstate:

An item placeholder must be specified on ListView 'lvList'. Specify an item placeholder by setting a control's ID property to "MyLayout$itemPlaceholder". The item placeholder control must also specify runat="server".

bei System.Web.UI.WebControls.ListView.GetPreparedContainerInfo(Control outerContainer, Boolean isItem, Int32& placeholderIndex)

bei System.Web.UI.WebControls.ListView.CreateItemsWithoutGroups(ListViewPagedDataSource dataSource, Boolean dataBinding, InsertItemPosition insertPosition, ArrayList keyArray)

bei System.Web.UI.WebControls.ListView.CreateChildControls(IEnumerable dataSource, Boolean dataBinding)

bei System.Web.UI.WebControls.ListView.CreateChildControls()

bei System.Web.UI.Control.EnsureChildControls()

I have opened a thread with the complete sourcecode:

Thanks again and kind regards
