DataGridView Row Select with EditMode=EditOnEnter by michaelAngeloEgypt

Thank you for your feedback. We are investigating this issue.

Thank you, Visual Studio Product Team.

Thanks for your feedback. This behavior is by design. The editing control has focus and gets the Del keystroke, and handles it. You can handle the Del key by deriving from the DataGridView control and overriding the ProcessDataGridViewKey method:

    public class MyDataGridView : DataGridView
    {

        protected override bool ProcessDataGridViewKey(KeyEventArgs e)
        {
            // intercept the Del key here
            return base.ProcessDataGridViewKey(e);
        }
    }

Thank you.

This is bad design then. You click the row header and instead of selecting or setting focus to the entire row it selects a particular cell?!? Who came up with this idea? By Design? More like someone to lazy to fix a bug.

I completely agree. This is bad design.
If have a whole row selected. Then delete should have different behaviour.
Dear Microsoft.
Please fix this? The grid would be so much cooler if you do.

You have to use the CellEnter and MouseClick events of a DataGridView class.

1) Place this code in the CellEnter event handler:

     Dim dgv As DataGridView = DirectCast(sender, DataGridView)

     dgv.EditMode = DataGridViewEditMode.EditOnEnter


2) Place this code in the MouseClick event handler:

     Dim dgv As DataGridView = DirectCast(sender, DataGridView)

     Dim hti As DataGridView.HitTestInfo = dgv.HitTest(e.X, e.Y)

     If hti.Type = DataGridViewHitTestType.RowHeader Then

         dgv.EditMode = DataGridViewEditMode.EditOnKeystrokeOrF2

         dgv.EndEdit()

     End If

C# version for what its worth.
private void dataGridView_CellEnter(object sender, DataGridViewCellEventArgs e)
        {
            ((DataGridView)sender).EditMode = DataGridViewEditMode.EditOnEnter;
        }

        private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
        {
             DataGridView.HitTestInfo hti = mappingsDataGridView.HitTest(e.X, e.Y);

             if (hti.Type == DataGridViewHitTestType.RowHeader)
             {
                 ((DataGridView)sender).EditMode = DataGridViewEditMode.EditOnKeystrokeOrF2;
                 ((DataGridView)sender).EndEdit();
             }

        }
