RadTreeView inside RadComboBox

[Vitaly]

Hi,
the following code is in my aspx page:
 <telerik:RadComboBox ID="RadComboBoxStatusGrp" runat="server" Width="125px"
             Height="150px" Font-Size="Small" CssClass="txtinput" AutoPostBack="false"
             EmptyMessage="Choose a Status" ShowToggleImage="true"
              OnClientDropDownOpened="OnClientDropDownOpenedHandler">

             
      <ItemTemplate>
       <div id="div1">
       <telerik:RadTreeView runat="server" ID="RadTreeView1" OnClientNodeClicking="nodeClicking">
        <Nodes>
          <telerik:RadTreeNode runat="server" Text="TR" Expanded="true" >
           <Nodes>
            <telerik:RadTreeNode runat="server" Text="Approved"  >
            </telerik:RadTreeNode>
             <telerik:RadTreeNode runat="server" Text="Entered"  >
             </telerik:RadTreeNode>
             <telerik:RadTreeNode runat="server" Text="All Trans" >
             </telerik:RadTreeNode>
            
            </Nodes>
            </telerik:RadTreeNode>
            </Nodes>  
            <Nodes>
             <telerik:RadTreeNode runat="server" Text="Processed"  Expanded="true"></telerik:RadTreeNode>
            </Nodes>
            <Nodes>
             <telerik:RadTreeNode runat="server" Text="All" Expanded="true"></telerik:RadTreeNode>
            </Nodes>  
       </telerik:RadTreeView>
       </div>
      </ItemTemplate>
      <Items>
        <telerik:RadComboBoxItem Text="" />
      </Items>
     </telerik:RadComboBox>
      <script type="text/javascript">
          var div1 = document.getElementById("div1");
          div1.onclick = StopPropagation;
     
   </script>

In C# on page_load event I am reading SP and get field call RunFlag.
If RunFlag == "I"
 disable "Processed" node.
How can I do that?

Thanks so much for your help

Hi Vitaly,

You can easily find the RadTreeVIew control in the RadComboBox by using the following code

var treeviewInCombo= RadComboBox2.Items[0].FindControl("RadTreeView1");

After you get reference to the needed control you can set the desired node as per your requirements. Here is a help article that you can refer that can provide you more information and sample how to find the node.
