Alternative to Cell End Edit in Datagridview ?

I think you can use KeyPressEventHandler, it is probably the same in VB, but I don't know the syntax. Here is a C# code for your reference:

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
  {
      DataGridViewTextBoxEditingControl tb = (DataGridViewTextBoxEditingControl)e.Control;
      e.Control.KeyPress += new KeyPressEventHandler(dataGridViewTextBox_KeyPress);
  }
  private void dataGridViewTextBox_KeyPress(object sender, KeyPressEventArgs e)
  {
       MessageBox.Show(e.KeyChar.ToString());
  }
