I got to delete the menu like this:
RadTabbedFormControl.ContextMenuOpening += (obj, arg) => { arg.ContextMenu.Items.Clear();};And to make a new menu, I tried to do it using MouseDown:
e.Tab.Item.MouseDown += (obj, args) => { if(args.Button == MouseButtons.Right) { ContextMenu testMenu= new ContextMenu(); testMenu.MenuItems.Add("Test"); testMenu.Show(e.Tab, new Point(args.Location.X + 5, args.Location.Y - 35)); }};But there was a problem with the error (Unable to display ContextMenu in invisible control) when clicking on an inactive tab.
Can you tell me another way?

Hello, Serg,
It is possible to modify the items in the context menu by handling the RadTabbedFormControl.ContextMenuOpening event. You can clear the existing items and add new ones as demonstrated below:
private void RadTabbedFormControl1_ContextMenuOpening(object sender, RadTabbedFormControlItemConextMenuOpeningEventArgs e)
{
//clear items
e.ContextMenu.Items.Clear();
//add new item
RadMenuItem testItem = new RadMenuItem();
testItem.Text = "test menu item";
e.ContextMenu.Items.Add(testItem);
}
According to your last question, I suppose that you have disabled a tab so it becomes inactive and then the context menu doesn't show. Note, the point of making a tap inactive/disabled is that nothing will work on it at all. Thus, it is expected that the context menu wouldn't show.
I hope this information helps. If you need further assistance please let me know.
Regards,
Nadya
