Hi all,

I have installed ASP.NET AJAX 1.0 (the 01/23/2007 release)
I have a usercontrol with a Panel then a Repeater surrounded by an UpdatePanel.

In the ItemDataBound, I dynamically (= in code-behind) add a HoverMenuExtender to each item of the repeater.

As you can see, HoverMenuExtender tries to populate the label labelApres2 in my panel panelApres1 with a web service GetContent included in the code-behind as follows :

Note : I also have added [System.Web.Script.Services.ScriptService] before my class where all my code behind resides.

Unfortunately, when I mouseover the tdPictoType cell, all is displayed is  "This popup popped at Web Service call failed: 500 and all was well."

Note : on the same page/usercontrol, my tests with HoverMenuExtender without a webservice/dynamic attributes do work. 

My questions are :

1 - did I miss an important section in the Web.config in order for web services to work ?

2 - is my syntax of my webservice and its call correct ? (ie the [System.Web.Script.Services.ScriptService] and [System.Web.Services.WebMethod()]) 

I used the slightly outdated site

dynamic-content-made-easy-redux-how-to-use-the-new-dynamic-population-support-for-toolkit-controls

Thank you for your help !

Let me reply to myself :

I've just fount out that I needed to place the webmethod (the following code snippet) in the page itself, NOT in the usercontrol !

<script runat="server">
[System.Web.Script.Services.ScriptMethod]
[System.Web.Services.WebMethod()]
public static string GetContent(string contextKey)
{
  string sIndName = contextKey;
  return "<span style='color:blue;font-size:14pt'>" + sIndName + " " + DateTime.Now + "</span> ";
}
</script>

Hi oudoulj

I followed my problem to this post and solved it. What I was wondering is how come I have to place this code snippet in my aspx page and not in the usercontrol? I'm asking this because I have to return the dynamic data based on some ViewState properties in my UserControl!

Thx in advance

I'm afraid I cannot answer your question but since my last post here I switched to a ModalPopupExtender (instead of a HoverMenuExtender).

In my usercontrol code-behind, I dynamically build a ModalPopupExtender for each item of my repeater :

1    private void RL_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
2    {
3    //...
4    ModalPopupExtender mpe1 = new ModalPopupExtender();
5    mpe1.TargetControlID = ((Label)e.Item.FindControl("Nom_Prenom")).UniqueID; ;
6    mpe1.PopupControlID = pTest.ID;
7    mpe1.BackgroundCssClass = "background";
8    mpe1.DynamicControlID = label2.ID;
9    mpe1.DynamicContextKey = IndTmp.ID.ToString();
10   mpe1.DynamicServiceMethod = "GetFiche";
11   mpe1.DynamicServicePath = "http://localhost/annuaire/rech_coord/wsFicheIndividuelle.asmx";
12   mpe1.OkControlID = bCloseModal1.ID;
13   mpe1.CancelControlID = bCloseModal2.ID;
14   mpe1.PopupDragHandleControlID = pTitreFiche.ID;
15   
16   up1.ContentTemplateContainer.Controls.Add(mpe1);
17   //...
18   }

where up1 is an UpdatePanel surrounding my repeater in design view.
As you can see, I'm able to call a web method in a web service (the web service can even be on remote machine as long as the path is correct I guess)

Hope this helps if you try to do something similar with your HoverMenuExtender.
