Control nextControl;
if (e.KeyCode == Keys.Enter)
{     
    nextControl = GetNextControl(ActiveControl, !e.Shift);
    if (nextControl == null)
    {
        nextControl = GetNextControl(null, true);
    }
    nextControl.Focus();               
    e.SuppressKeyPress = true;
 }
I have this code to act ENTER Key as TAB but when I press Enter key it is selecting textbox value as in image

                        
You can tell the TextBox to select nothing
