I have a treeview with Radcontextmenu, and itemplate contains other control..., when i make button_click that is a button into a itemplate.., i can't accessing control into itemplate..for example for set visible = false the controls that are inside the itemplate..

What is the code for findcontrol into an itemtemplate?

Hi Rubihno,

You need to find the node and then search withing the Controls collection of the node:

RadTreeNode node = RadTreeView1.FindNodeByText("My Node");
Button btn = (Button)node.FindControl("Button1");
btn.Text = "My new button text";

I hope this helps.

All the best,

            Enabled="true" AllowNodeEditing="false" ExpandAnimation-Type="InElastic"
            EnableDragAndDrop="True" EnableDragAndDropBetweenNodes="True"
            MultipleSelect="True" SingleExpandPath="true" ShowLineImages="true" >

       <telerik:RadTreeViewContextMenu runat="server" ID="HelpDeskMenu" ClickToOpen="True" Skin="Vista">
           <Items>
           <telerik:RadMenuItem  Text="New"  Visible="true">
         <ItemTemplate>

         <asp:button ID="test1" runat="server" OnClick="test1_Click"/>
         <asp:Button ID="test2" runat="server" />

         </ItemTemplate>
           </telerik:RadMenuItem>
           </Items>

Hi Rubihno,

Try the following code snippet to achieve the desired scenario.

VB:

     Protected Sub test1_Click(sender As Object, e As EventArgs)
         Dim btnTest1 As Button = DirectCast(sender, Button)
         Dim menuitem As RadMenuItem = DirectCast(btnTest1.NamingContainer, RadMenuItem)
         Dim btnTest2 As Button = DirectCast(menuitem.FindControl("test2"), Button)
         btnTest2.Visible = False
     End Sub

Regards
Shinu.
