Hi,

 

I'm new to the dapfor grid and just wanted to know if it's possible to disable the scrollbars.

 

Thanks,

 

Michel

  Hi,

  Which scrollbars do you want to disable? Vertical or horizontal one? Do you mean to disable or to hide them?

  Regards,

  Hi,

  You can hide the horizontal scrollbar by stretching header columns :

  grid.Headers[0].StretchMode = ColumnStretchMode.All;

  What is about vertical scrollbar – you can’t do it in the current version, but we'll add this feature into the next version of the grid.

  Best Regards,

  Thanks! I was able to solve this for now using the following code (in case anyone else is interested)

   

  public class NoScrollBarGrid : Dapfor.Net.Ui.Grid
  {
  protected override void WndProc(ref Message m)
  {
  switch (m.Msg)
  {
  case 0x83: // WM_NCCALCSIZE
  int style = (int)GetWindowLong(this.Handle, GWL_STYLE);
  if ((style & WS_VSCROLL) == WS_VSCROLL)
  SetWindowLong(this.Handle, GWL_STYLE, style & ~WS_VSCROLL);
  if ((style & WS_HSCROLL) == WS_HSCROLL)
  SetWindowLong(this.Handle, GWL_STYLE, style & ~WS_HSCROLL);
  base.WndProc(ref m);
  break;
  default:
  base.WndProc(ref m);
  break;
  }
  }
  const int GWL_STYLE = -16;
  const int WS_VSCROLL = 0x00200000;
  const int WS_HSCROLL = 0x00100000;

  public static int GetWindowLong(IntPtr hWnd, int nIndex)
  {
  if (IntPtr.Size == 4)
  return (int)GetWindowLong32(hWnd, nIndex);
  else
  return (int)(long)GetWindowLongPtr64(hWnd, nIndex);
  }

  public static int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong)
  {
  if (IntPtr.Size == 4)
  return (int)SetWindowLongPtr32(hWnd, nIndex, dwNewLong);
  else
  return (int)(long)SetWindowLongPtr64(hWnd, nIndex, dwNewLong);
  }

  [DllImport("user32.dll", EntryPoint = "GetWindowLong", CharSet = CharSet.Auto)]
  public static extern IntPtr GetWindowLong32(IntPtr hWnd, int nIndex);

  [DllImport("user32.dll", EntryPoint = "GetWindowLongPtr", CharSet = CharSet.Auto)]
  public static extern IntPtr GetWindowLongPtr64(IntPtr hWnd, int nIndex);

  [DllImport("user32.dll", EntryPoint = "SetWindowLong", CharSet = CharSet.Auto)]
  public static extern IntPtr SetWindowLongPtr32(IntPtr hWnd, int nIndex, int dwNewLong);

  [DllImport("user32.dll", EntryPoint = "SetWindowLongPtr", CharSet = CharSet.Auto)]
  public static extern IntPtr SetWindowLongPtr64(IntPtr hWnd, int nIndex, int dwNewLong);

  }
