Hi,

Base on your description, you want to add the hoverMenu for the treenode, right?

But the treeview is some tables at runtime, you cannot get the treenode's id, but you can do like below:

1. The aspx code:

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" OnTreeNodeDataBound="TreeView1_TreeNodeDataBound"
            ShowLines="True">
        </asp:TreeView>
        <asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px" Style="display: none">
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        </asp:Panel>
        <cc1:HoverMenuExtender ID="HoverMenuExtender1" runat="server" BehaviorID="myHMEBID"
            PopupControlID="Panel1" TargetControlID="Button1">
        </cc1:HoverMenuExtender>
        <div style="display: none">
            <asp:Button ID="Button1" runat="server" Text="Button" /></div>

2. the treeview 's TreeNodeDataBound event code:

 int myIndex = 0;

protected void TreeView1_TreeNodeDataBound(object sender, TreeNodeEventArgs e)
    {
        e.Node.Text = "&lt;div id='myDiv" + myIndex.ToString() + "' onmouseover='showHoverMenu(\"myDiv" + (myIndex++).ToString() + "\")' onmouseout='hideHoverMenu()'>" + e.Node.Text + "&lt;/div>";
    }

3. the javascript:

 <script language="javascript" type="text/javascript">    
        var activeDivID="";
        function pageLoad(){
           $find("myHMEBID").add_shown(onHoverMenuShown11);
        }
        function onHoverMenuShown11(){
          var activeDivLocation = $common.getLocation($get(activeDivID));
          $common.setLocation($find("myHMEBID").get_popupElement(),new Sys.UI.Point(activeDivLocation.x + $get(activeDivID).offsetWidth,activeDivLocation.y));
          $get("<%=TextBox1.ClientID %>").value = $get(activeDivID).innerText;
        }
        function showHoverMenu(divID){
           activeDivID = divID;
           $find("myHMEBID")._onUnhover();   
           $find("myHMEBID")._onHover();
        }
        function hideHoverMenu(divID){
           $get("<%=Panel1.ClientID %>").style.display= "none";
        }

    </script>

Hope it helps.

Wow! That is so cool!

Thank you very much.

Hi, i'd like to get treeView and HoweMenuExtender working together, too.

I tried to do a test page with Amanda's code and I'm getting TAGGY (instead of clear text) tree nodes in UI:

&lt;/div>" src="...">
<div id='myDiv0' onmouseover='showHoverMenu("myDiv0")' onmouseout='hideHoverMenu()'></div>        
<div id='myDiv1' onmouseover='showHoverMenu("myDiv1")' onmouseout='hideHoverMenu()'>Gauti prane?imai</div>        
<div id='myDiv2' onmouseover='showHoverMenu("myDiv2")' onmouseout='hideHoverMenu()'>Atrinkti prane?imai</div>

and an ERROR image in a leftbottom conner  of a browser with a error message: "Object doesn't support this property or method" with a line number, which corresponds to a script  $find("myHMEBID").add_shown(onHoverMenuShown11);

WHAT I'm doing wrong? Do I missed any declaration or something else? 

THANKS in advanse.

Hi

if you want to use $find("myHMEBID").add_shown(onHoverMenuShown11);  the ScriptManager is prerequisite.

That is to say, there must be ScriptManager on the page.

<asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>

 or else, you should use the method: document.getelemetbyid.

Hope it helps.

Hi:

I am trying to use your solution and get te following error!

Any help would be appreciated.

Thanks Len

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
