Context Menu in Node and Sub Node Issue

[Sasmita]

Hi ,

I am using a RadTreeNode, tree Structure is given below.                         

Label-0
       Label0-1 -- Context Menu -1 is assigned to this node
               Label0-1-1 Context Menu -2 is assigned to this node
               Label0-1-2 Context Menu -2 is assigned to this node

        Label0-2
              Label0-2-1
                Label0-2-2  
Label-1
                    

I have assigned “Context Menu -1” to  Label0-1 and “Context Menu -2” to Label0-1-1  as shown above .

When I do a right click on node Label0-1-1, for first time “Context Menu 1” 1 is showing , next time when I do a right click then it’s showing “Context Menu 2”. I mean sub nodes are showing the context menu of the Parent node for the first time and second time when you do a right click it shows the proper context menu. 

Could any body please help me out .

Hi Sasmita,

I tried to reproduce the issue you describe but to no avail. I've tried using the Q1 2008 SP1 version so I am making a guess that it must be an issue related to an older version of RadControls for WinForms. Could you, please elaborate a bit more and tell me which version you are using?

You can find attached the sample project that I used for testing.

Looking forward to your reply.

All the best,

Hi I am so sorry. I could not attach the solution file which i had developed for testing.

Could you please just look at the below code and let me know where i am wrong.

In the Form_Load event i am Creating the Tree View and in the ContextMenuShowing event i am assigning the respective Context Menus to nodes.

So when i first time click on the Node 1 and Node 2 they are showing Level 0 only and for second time onwards,  they are showing the proper context menu assigned to them.

Regards,
Sasmita

Hi Sasmita,

I tried the code and I believe that I found the solution.
In order to apply the menu right away, you need to set the ContextMenu property to the event arguments like:

private void radTreeViewTest_ContextMenuShowing(object sender, ContextMenuShowingEventArgs e)
        {
            if (e.Node.Level == 0)
            {
                e.ContextMenu = menu;
                e.Node.ContextMenu = menu;
            }

            if (e.Node.Level == 1)
            {
                e.ContextMenu = menu1;
                e.Node.ContextMenu = menu1;
            }

            if (e.Node.Level == 2)
            {
                e.ContextMenu = menu2;
                e.Node.ContextMenu = menu2;
            }
        }

Please, give it a try and tell us if you have further problems.
