  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????

  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,
