Radtreeview problem with client-side find

[Ken]

Hello:

I've been scratching my head for two days for trying to migrating to the new ajax version of radtreeview.
I have read your tutorials and have tried almost everything mentioned from registering the telerik assembly to creating a radtree with radajaxmanager. The sample program compiles correctly but when I tried to access a tree using javascript (within radcodeblock) using:
var treeView = $find("RadTreeView2");
...
...
<telerik:RadTreeNode runat="server" Text="Products" ExpandMode="ClientSide">
               <Nodes>
                   <telerik:RadTreeNode runat="server" Text="Books" ExpandMode="ClientSide">
                   <Nodes>
                       <telerik:RadTreeNode runat="server" Text="Fiction"></telerik:RadTreeNode>
                       <telerik:RadTreeNode runat="server" Text="Non-Fiction"></telerik:RadTreeNode>
                       <telerik:RadTreeNode runat="server" Text="Biography"></telerik:RadTreeNode>
                       <telerik:RadTreeNode runat="server" Text="Humor"></telerik:RadTreeNode>
                   </Nodes>
                   </telerik:RadTreeNode>
               </Nodes>
           </telerik:RadTreeNode>
           </Nodes>
       </telerik:RadTreeView>
...



After debugging, it shows that the find did nothing and treeView is null.
Is there any explaination to this?

Hi Ken,

 

I am not sure about what is happening at your side. How are you calling the function to getting the RadTreeView client side object? I tried getting the RadTreeView from a button click event handler and it is working for me. Check the below code and see whether it is working fine for you.

Here's the ASPX:

<script type="text/javascript">
function gettreeview()
{
    var treeView = $find("RadTreeView2");   //get the client side object
}
</script>
</telerik:RadCodeBlock>
<telerik:RadTreeView ID="RadTreeView2" Runat="server">
<Nodes>
    <telerik:RadTreeNode runat="server" Text="Products" ExpandMode="ClientSide">
       <Nodes>
           <telerik:RadTreeNode runat="server" Text="Books" ExpandMode="ClientSide">
           <Nodes>
               <telerik:RadTreeNode runat="server" Text="Fiction"></telerik:RadTreeNode>
               <telerik:RadTreeNode runat="server" Text="Non-Fiction"></telerik:RadTreeNode>
               <telerik:RadTreeNode runat="server" Text="Biography"></telerik:RadTreeNode>
               <telerik:RadTreeNode runat="server" Text="Humor"></telerik:RadTreeNode>
           </Nodes>
           </telerik:RadTreeNode>
       </Nodes>
   </telerik:RadTreeNode>
   </Nodes>
</telerik:RadTreeView>
<input id="Button1" type="button" value="Get the tree" onclick="gettreeview();"/>

Thanks,
Shinu.
