Hi,

I'm trying to use the OnNodeClick method of the TreeView to trigger an server side event but it seems that I've made any mistake.
I've set the OnNodeClick attribute as you can see in my ASP code:

    
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"> 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="RadGrid1"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label2" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label3" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="Label4" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager> 
        
            [...] 
        
            <telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="Office2007" OnNodeClick="RadTreeView1_NodeClick"> 
        
                            <Nodes> 
        
                                <telerik:RadTreeNode runat="server" Text="Postfach" Expanded="true" > 
        
                                    <Nodes> 
        
                                        <telerik:RadTreeNode runat="server" Value="in" Text="Empfangen" PostBack="False"> 
        
                                        </telerik:RadTreeNode> 
        
                                        <telerik:RadTreeNode runat="server" Value="out" Text="Gesendet" PostBack="False"> 
        
                                        </telerik:RadTreeNode> 
        
                                    </Nodes> 
        
                                </telerik:RadTreeNode> 
        
                            </Nodes> 
        
                        </telerik:RadTreeView> 
        
            [...] 
        
            <asp:Label ID="Label5" runat="server" Text="Label"></asp:Label>

And wrote a very short server side command for debugging, just trying to change the text of an label, but nothing changes onlclick.

    
                    protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e) 
        
                    { 
        
                        Label5.Text = "Node Clicked"; 
        
                    }

I'm quite sure that I've made a very stupid mistake but I can't find out whats going wrong.

Any help is highly appreciated.

Kind Regards
