I am having a context menu displayed when i right click on a node

  • 0

I am having a context menu displayed when i right click on a node of a treeview. Suppose my treeview is as follows

Root
|->some.txt
|-> Child(For some.txt)
|-> Child1(child for Child)

If i right click on Child1 i will have an option as AddNew. If the user selects i will show a user control form for the user displayed in a panel.

What i need is if the user selects the option as Child1 and if the user control is active and when the user again right clicks on Child1 i would like to make the context menu as non-selectable field. Can any ine tell how to do.

    Any modifications as to the selectability of ContextMenu Items depending on a scenario can be done in the Opening event of the ContextMenu.

    • Make sure you have a way of determining whether the usercontrol is visible (flag, Visibility, check for != null…whatever is appropriate in your situation)

    • define an opening handler for your contextmenu

    • in the opening handler, check if control is visible (see point 1)

    • if so, set the menu item’s enabled status to false, otherwise to true.
