hello,

I use a textbox on datagridview for input, the below

at event load

datagridview.controls.add(textbox);

textbox.Visible=false;

at eventCellEnter

rect = datagridview.GetCellDisplayRectangle(datagridview.CurrentCell.ColumnIndex, datagridview.CurrentCell.RowIndex, false);
textbox.Left = rect.Left;
textbox.Top = rect.Top;
textbox.Width = rect.Width;
textbox.Height = rect.Height;
textbox.Text = datagridview.CurrentCell.Value.ToString();

textbox.Visible=true;

why i cann't put 'q' into textbox ?

thanks a lot.

Is the 'q' on your keyboard working?

Really though I can't think of a reason you can't put a q in a textbox, unless of course you mean you can't insert any character what so ever?

the keybord is well,this problem happento every user.only 'q' cann't put into textbox

thank you for your answer,

I use PreviewKeyDown.

switch (e.KeyData)
{
case Keys.Enter:

break;

default:

break;

}

I have the same problem. I also found that delete key doesn't work either (it is hotkey for deleting selected row/column).After spending several hours I found how to solve the problem. In the control derived from DataGridView I overrode following method

Question to Microsoft developers: Why did call to DataGridView.ProcessKeyPreview returned true when user clicked Q key? I didn't find this to be hotkey for any action. Are there any other keys that might not work (e.g. some other key on non-Enlish keyboard)?
