Hi Falk,

Try subscribing to the ContectMenuOpeningEventHandler event on your grid:

    
             myGrid.ContextMenuOpening += new ContextMenuOpeningEventHandler(myGrid_ContextMenuOpening);

And then in that event:

    
            void _rgvVehicleHistory_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)  
        
            {  
        
                e.Cancel = true; // This hides all context menus completely  
        
               // OR  
        
               e.ContextMenu = myContextMenu; // To show your context menu  
        
            }

Hope that helps!

Justin

HI, Raviraj, If you want to disable the default context menu in RadGridView, feel free to cancel the ContextMenuOpening event:

        private void RadGridView1_ContextMenuOpening(object sender, 
            Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)
        {
            e.Cancel = true;
        }

Thanks, that works , sort of.

During the initialization of my Form I set the ContextMenuStrip

    
            RadGridView1.ContextMenuStrip = MyContextMenu

Then I subscribed to the event as you said.

    
            Private Sub RadGridView1_ContextMenuOpening(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles RadGridView1.ContextMenuOpening 
        
              e.Cancel = True 
        
            End Sub

This actually cancels only the default contextmenu. MyContextMenu is still shown, so this is what I want. Still a bit strange, there seem to be two different ContextMenus.

Thanks for your help!

Hello Iam,

Thank you for the question. You can access the ContextMenu in ContextMenuOpenning event handler and customize it according to your needs. For example if you want to leave only Delete Row item in the DataCell context menu you can use the following code:

    
            void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e) 
        
            { 
        
                GridDataCellElement cell = e.ContextMenuProvider as GridDataCellElement; 
        
                if (cell != null) 
        
                { 
        
                    RadItem deleteItem = e.ContextMenu.Items[4]; 
        
                    e.ContextMenu.Items.Clear(); 
        
                    e.ContextMenu.Items.Add(deleteItem); 
        
                } 
        
            }

I hope this helps. Write me back if you need additional assistance.

All the best,

Hi NORIS,

As I can see, you are using an old version of RadControls for WinForms. You should not experience these issues with our latest release - Q2 2009 SP1. I recommend that you try out this version. It contains many improvements and addresses a lot of issues. I will be glad to help you with the transition process.

If you continue experiencing the issue, please send me your project and I will try to locate it. I am looking forward to your reply.

Kind regards,
Jack
