P: 1
I want to catch Enter Key with KeyDown Event in TextColumn of DataGridView Control. When I press Enter in the txtItemCode column, I will check the ItemCode in the Database and other stuffs. I can get other keys but I can't get Enter. When I hit the Enter key, The focus is go to next row same column. How could I catch the Enter Key. I can catch with PreviewKeyDown Event but The Event occur from other columns also. I just want to catch from single column. I already googled but found nothing. Below is my code. Help me please.

  1. Private Sub g_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles g.EditingControlShowing
  2.     Select Case g.CurrentCell.ColumnIndex
  3.         Case 0
  4.             Dim t As TextBox
  5.             t = e.Control
  6.             t.AcceptsReturn = False
