Hi Amit,

I guess you have placed RadComboBox in GridTemplateColumn of grid like the setup shown below. If so you can access the RadComboBox by accessing the RadComboBoxItem and then the RadComboBox by using NamingContainer property. Give a try with following code and see whether this help you.

ASPX:

    
             . . .  
        
            <telerik:GridTemplateColumn UniqueName="TemplateColumn">  
        
                <ItemTemplate> 
        
                    <telerik:RadComboBox ID="RadComboBox1" runat="server" Height="300px">  
        
                        <Items> 
        
                            <telerik:RadComboBoxItem runat="server" /> 
        
                        </Items> 
        
                        <ItemTemplate> 
        
                            <telerik:RadTreeView ID="RadTreeView1" runat="server" OnNodeClick="RadTreeView1_NodeClick">  
        
                                <Nodes> 
        
                                 . . .  
        
                                </Nodes> 
        
                            </telerik:RadTreeView> 
        
                        </ItemTemplate> 
        
                    </telerik:RadComboBox> 
        
                </ItemTemplate> 
        
            </telerik:GridTemplateColumn> 
        
             . . .

C#:

    
            protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)  
        
            {  
        
                RadTreeView tree = (RadTreeView)sender;  
        
                RadComboBoxItem comboItem = (RadComboBoxItem)tree.NamingContainer;  
        
                RadComboBox combo = (RadComboBox)comboItem.NamingContainer;  
        
            }

Thanks,
Princy.

Hi Amit,

I tried following approach to get reference to client object of RadComboBox in OnClientNodeClicking event of RadTreeView. Give a try with the following code.

JavaScript:

    
            <script type="text/javascript"> 
        
            function OnClientNodeClicking(sender, args) 
        
            { 
        
                var text=sender.get_id(); // ClientID of RadTreeView 
        
                var index=text.lastIndexOf("RadComboBox1"); // RadComboBox1 is the ID of combobox 
        
                var ClientID=text.substring(0,index+12); 
        
                var combo = $find(ClientID); // Get reference to RadComboBox 
        
                alert(combo.get_text()); 
        
            } 
        
            </script>

Shinu.
