Disable / Remove Context menu Items on right click

[Chinna]

hi,
     I want to disable / remove context menu items on treeview item right click


Scenario:

I have a treeview of the following structure:

Root --> Item1.1
         -->Item1.2--->Item1.2.1
         -->Item1.3-->Item1.3.1

My Context Menu with Items A,B,C,D,E

On Root node right click i have to get only Context menu Item A only other items have to be disbaled / removed from the context menu.

Similarly on Item 1.1 right click i have to get Item B,C in the context menu.


Quick help in this regard will be helpful.

Thanks,

Vinod.

Hi Vinod,

One of the approaches is to define different RadContextMenus for root nodes and for child nodes.
Then depending on the item that is right clicked you will show either the first or the second menu.

I have prepared a small project for you. Please download it and give it a try.

I hope this helps.

All the best,

Hi Veskoni,
                    I can't have two Context menus in this context, I can have only one is there any way to remove items dynamically on right click by getting the type of the node.

hi,
        Can i disable/remove the items on node databound

Thanks,

Vinod

Hello Vinod,

On NodeDatabound event you can set the Enabled and/or Visible properties of the node to True / False.

Also you can use the client-side methods enable/disable or hide/show.

More information is available in our online help: RadMenuItem object

Hi Veskoni,
                    My query is not about disabling nodes of a tree view. I want to disable Context menu items based on the node selected.


Thanks,

Vinod.

Hello Vinod,

You can use the client-side methods enable/disable or hide/show of RadMenuItem object.

Hi Srihari,

I would suggest you to take a look at the TreeView Context Menus demo and the help articles referenced at its About this demo section. They would help you achieve the desired functionality.

Hi Srihari,

I am afraid that I cannot reproduce such an issue on my side with our latest version Q2 2015 SP1. Here is a screenshot of the RadTreeView and ContextMenu I observe. Could you test with our latest version as it should fix the issue? I tested Firefox, Chrome, IE7+ browsers.
