now i run into a problem of how to detect that that button was clicked? say i have this structure
panelbar
   item
      panelitem
          item
            panelitem
                itemtemplate
                        button1
                         button2
so how do i detect which button was click. the reason i ask because you have to create new variable inroder to receive the value of the button like this

Dim

btn1 As Button = DirectCast(RadPanelBar1.FindItemByValue("Name").FindControl("btn1"), Button)

so really the server side can't see the button it self because it is burried deep in the panelbar control. could you help? thanks.

Hi there,

You can hook to the Click events of the Buttons in the ASPX like this:

[ASPX]
    <form id="form1" runat="server"
        <asp:ScriptManager ID="ScriptManager1" runat="server"
        </asp:ScriptManager> 
        <div> 
            <telerik:RadPanelBar ID="RadPanelBar1" runat="server"
                <CollapseAnimation Type="None" Duration="100"></CollapseAnimation> 
                <Items> 
                    <telerik:RadPanelItem runat="server" Text="Root RadPanelItem1"
                        <Items> 
                            <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1"
                                <Items> 
                                    <telerik:RadPanelItem runat="server" Text="Child RadPanelItem 1"
                                        <ItemTemplate> 
                                            <asp:Button ID="Button1" runat="server" Text="Button1" OnClick="Button_Click" /> 
                                            <asp:Button ID="Button2" runat="server" Text="Button2" OnClick="Button_Click" /> 
                                        </ItemTemplate> 
                                    </telerik:RadPanelItem> 
                                </Items> 
                            </telerik:RadPanelItem> 
                        </Items> 
                    </telerik:RadPanelItem> 
                    <telerik:RadPanelItem runat="server" Text="Root RadPanelItem2"
                    </telerik:RadPanelItem> 
                </Items> 
                <ExpandAnimation Type="None" Duration="100"></ExpandAnimation> 
            </telerik:RadPanelBar> 
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label></div
    </form> 

And here is the event handler used by both Buttons:

[ASPX.VB]
    Protected Sub Button_Click(ByVal sender As ObjectByVal e As System.EventArgs) 
        Me.Label1.Text = TryCast(sender, Button).Text 
    End Sub
