The code

 
Private Sub DataGridViewEx_ColumnHeaderMouseClick (sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridViewEx. ColumnHeaderMouseClick 
Messagebox. Show (" 111 ") 
End Sub 

I literally point a column name will pop up messagebox

Want to cry, the reason was colleagues don't know when the blocked ColumnHeaderMouseClick events,,,
Come on, people pick up points
