    Hello,

    I have a question about the RadContextMenu. My problem is I am not able to open a RadContextMenu manually through the code.

    * I created a ContextMenu + MenuItems in code behind
    * I NOT called the function RadContextMenu.SetContextMenu
    * I set IsOpen = true for opening the menu => Error:  Unhandled Error (Application_UnhadledException) Object reference not set to an instance of an object

    What do I wrong, how can I open a ContextMenu through code behind????

    regards Richard Koslik

    Hi Richard,

    You should set a target to the context menu in order to open it properly. This can be done by other using SetContextMenu method as explained here or setting its PlacementTarget property:

    RadContextMenu contextMenu = new RadContextMenu();
    contextMenu.Items.Add(new RadMenuItem() { Header = "test item" });
    contextMenu.PlacementTarget = targetTextbox;
    contextMenu.IsOpen = true;

    Kind regards,
