I am trying to have a context menu in my grid but have no joy so far...

    
            <telerik:RadContextMenu ID="GridContextMenu" runat="server"> 
        
                <Targets> 
        
                    <telerik:ContextMenuControlTarget ControlID="RadGridKids" /> 
        
                    <telerik:ContextMenuControlTarget ControlID="Label1" /> 
        
                </Targets> 
        
                <Items> 
        
                    <telerik:RadMenuItem runat="server" Text="Root Stuff"> 
        
                        <Items> 
        
                            <telerik:RadMenuItem runat="server" Text="Child RadMenuItem 1"> 
        
                            </telerik:RadMenuItem> 
        
                            <telerik:RadMenuItem runat="server" Text="Child RadMenuItem 2"> 
        
                            </telerik:RadMenuItem> 
        
                        </Items> 
        
                    </telerik:RadMenuItem> 
        
                    <telerik:RadMenuItem runat="server" Text="Root Item 2"> 
        
                    </telerik:RadMenuItem> 
        
                </Items> 
        
            </telerik:RadContextMenu> 
        
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> 
        
            <telerik:RadGrid ID="RadGridKids" runat="server" GridLines="Horizontal" OnItemDataBound="RadGridKids_ItemDataBound" 
        
                AutoGenerateColumns="False" Height="99%" ShowStatusBar="True" GroupingEnabled="False"> 
        
                <MasterTableView CellSpacing="-1"> 
        
                    <RowIndicatorColumn> 
        
                        <HeaderStyle Width="20px" /> 
        
                    </RowIndicatorColumn> 
        
                    <ExpandCollapseColumn> 
        
                        <HeaderStyle Width="20px" /> 
        
                    </ExpandCollapseColumn> 
        
                    <Columns> 
        
                        <telerik:GridBoundColumn HeaderText="Node Description" UniqueName="NodeDesc"> 
        
                        </telerik:GridBoundColumn> 
        
                    </Columns> 
        
                </MasterTableView> 
        
                <ClientSettings> 
        
                    <Selecting AllowRowSelect="True" /> 
        
                    <Scrolling AllowScroll="True" UseStaticHeaders="True" /> 
        
                    <ClientEvents OnRowContextMenu="GridRowContextMenu" /> 
        
                </ClientSettings> 
        
            </telerik:RadGrid>

My grid is populated via assigning a DataSource in an Ajax Request.
In the ..._ItemDataBound, I assign a Tooltip to each item.

Before the Grid is populated, the code shows the context menu fine on the label and on the datagrid.
The GridRowContextMenu(...) does not fire which I suppose is normal since there are no rows.

After the grid is populated, the GridRowContextMenu() javascript fires all right but there is no more context menu on the Grid...

Am I supposed to do something when DataBinding the grid?

Thanks

Eric

Ok, there were so many examples to look at that I missed this bit!

I found a "dirty trick" but it sucks a bit so I'll switch to your advice.
On the ContextMenuShowing event, I spotted that the tagName of the TargetElement is TH for a header and TD for a row...

    
                    function GridCtxtMenuShowing(sender, eventArgs) {  
        
                        if ( eventArgs._targetElement.tagName == "TH" )  
        
                            eventArgs.set_cancel(true);  
        
                    }

Many Thanks.
