Hello San, There is no scrolling method in the control, but you can send WM_VSCROLL or WM_HSCROLL message to initiate scrolling. Here is small code sample as starting point: Code:[System.Runtime.InteropServices.DllImport("User32.Dll")]
internal static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
private const int WM_VSCROLL = 0x0115;
private const int WM_HSCROLL = 0x0114;
private const int SB_LINEUP = 0;
private const int SB_LINEDOWN = 1;
private const int SB_PAGEUP = 2;
private const int SB_PAGEDOWN = 3;
private void _scrollUpButton_Click(object sender, System.EventArgs e)
{
SendMessage(thumbnailListView1.Handle, WM_VSCROLL, SB_PAGEUP, 0);
}
private void _scrollDownButton_Click(object sender, System.EventArgs e)
{
SendMessage(thumbnailListView1.Handle, WM_VSCROLL, SB_PAGEDOWN, 0);
}
