Hi again!
How can I check if context menu is displayed?
I have a mouse_click event and if the user right clicks off a row (into white space) I display a custom popup. However, when the user right clicks on a row, the context menu pops up and then my menu pops up over top.
What i need to do is to determine whether the user right clicked on a row, or on white space so i can avoid showing my popup if they right clicked on a row.
Thanks.

How can you check from a thread within a Form if the contextmenu of a radgridview is diplayed or if it is hidden?

Hello, Apostolos,
The default context menu of RadGridView is displayed when you right-click a grid's cell. In the ContextMenuOpening event you can subscribe to the ContextMenu.DropDownOpened and ContextMenu.DropDownClosed events in order to detect when the context menu is opened/closed.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

private void radGridView1_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
e.ContextMenu.DropDownOpened -= ContextMenu_DropDownOpened;
e.ContextMenu.DropDownOpened += ContextMenu_DropDownOpened;
e.ContextMenu.DropDownClosed -= ContextMenu_DropDownClosed;
e.ContextMenu.DropDownClosed += ContextMenu_DropDownClosed;
