Shame about the sealed class but thank you very much for the attached source!

The SharePoint Products and Technologies Team Blog published the MossMenu source code. The AspMenu class

I noticed a bug in the MossMenu code you provided: when you select as subsite in the navigation, it doesn't set the menu item as selected.

here's how I fixed this :

if (SPContext.Current.ListItemServerRelativeUrl.ToLower() == e.Item.NavigateUrl.ToLower()){

e.Item.Selected = true;}

Hope it helps

oops I am sorry to have forgotten to mention that (and for the late reply)

it's in the OnMenuItemDataBound event, just after the base.OnMenuItemDataBound(e);

:)

Our customer wanted us to use graphics instead of text for menu items.  Since most of this stuff is brand new, I was left to my own devices and came up with this customization of MossMenu.  Thought I would throw it out here for conversation, since there seemed to be no other way to set the ImageURL property for each top-level menu item in MOSS and the database did not seem to have a field in which to store one for the menu.  I added the following code to the end of the OnPreRender() event:

// BEGIN CODE SNIPPET

try

{

   bool listOk = false;

   SPWeb mySite = SPContext.Current.Site.RootWeb;

   SPList lst = null;

   try

   {

       lst = mySite.Lists["Site Collection Images"];

       listOk = true;

   }

   catch

   {

       // (do nothing)

   }

   if (listOk == true)

   {

       SPQuery qry = new SPQuery();

       qry.Query = "<Where><BeginsWith><FieldRef Name=\"Title\"/><Value Type=\"Text\">nav_</Value></BeginsWith></Where>";

       SPListItemCollection myItems = lst.GetItems(qry);

       string imgname = "";

       for (int ix = 0; ix < this.Items.Count; ix++)

       {

           imgname = "nav_" + this.Items[ix].Text.Replace(" ", "").ToLower();

           foreach (SPListItem item in myItems)

           {

               if (item["Title"].ToString() == imgname)

               {

                   this.Items[ix].ImageUrl = @"/SiteCollectionImages/" + imgname + ".jpg";

                   this.Items[ix].Text = "";

                   break;

               }

           }

           imgname = "";

       }

   }

}

catch (Exception ex)

{

   if (this.Items.Count >=1)

       this.Items[0].Text = "Menu error: " + ex.Message;

}

// END CODE SNIPPET

Deployed MossMenu to the GAC, made a custom version of master.default for our site collection that consumed MossMenu, and assigned NEWMSTR.default to the top-level site and all sub-sites.  After that, uploaded menu graphics to the Site Collection Images document library, approved all of them, and edited each one's Title property to be nav_ plus the text of the menu item (for example, nav_contactus for a Contact Us site).  (The filename of the graphic is unimportant as long as it ends in .jpg, since the Title is a separate property of the graphic in the Site Collection Images library, so there is independence from the file system naming conventions for the sites.)  New sites will automatically be assigned a graphic when the content person uploads one, approves it, and sets its Title property appropriately.

It is assumed that the MossMenu's scope is that of the site collection and that all localized versions of the graphics are stored there, which may or may not be the case.

Andries,

No I have not seen it happen.  I have just tested it.  We are using IE 7.  Mine is 7.0.5730.11.  I am not sure if the IE version matters.  To learn more about it, I walked through it.  In the MossMenu C# code, a call is made in OnPreRender() to Page.ClientScript.RegisterStartupScript() after calling base.OnPreRender(), which inserts a JavaScript code fragment, which was present in the source of the page.  Looking at the JavaScript code, it looks as though it is adding a 50 millisecond delay with a call of overrideMenu_HoverStatic() in CORE.JS.  There is an amazing amount of stuff going on in here to make things happen throughout, but maybe you could modify and put an alert() call in CORE.JS to see if the override function is being called, All that said, I am not close to the authors of this code so there might be other ways to look at this.

Hi,

I need to change the image in the Menuitems  "OnmouseOver" and "OnMouseout" events. Please let me know how to do it in the Moss Menu

         Thanks in Advance

We are also fasing the problem of the error "Internet Explorer cannot open the Internet site, Operation aborted". We have replaced AspMenu control with the MossMenu control. Yet i get the IE error.  I believe the problem is IE6 related - has anyone managed to find a solution for this yet?

Thanks

thanks so much for the source code to display images per subsite in teh menu.

How do I change it slightly to do mouseover and mouseout events ( in other words change my image in the menu with the mouse over event)

thanks

Hi,I am facing the same issue of "Internet Explorer cannot open the Internet site, Operation aborted" but when I googled , I found that if there's somejavascript code written within HTML then this occurs...

But I did not find anything in my code.

Now I got a solution to this issue i.e by replacing RegisterStartupScript by RegisterClientScriptBlock..But this leads to some other minute issue...Can someone please suggest me if I am going the right way?

The out of the box navigation controls work for many scenarios, but what happens if they don't? What
