using Syncfusion FlatScrollBar with standard TreeView

[Piotr]

Hi

I'm trying to use SF FlatScrollBars with generic System.Windows.Forms.TreeView. I know how to attach them, how to disable standard scrollbars and so on, but I don't know how to force TreeView to scroll in response to operations on FSB.

I was trying to send windows message to treeview (as in attachment) but it doesn't seem to work.

I'm using in myTreeView class:

[DllImport("user32.dll")]
public static extern long SendMessage(IntPtr hWnd, int msg, int wParam, IntPtr lParam);

and then

SendMessage(this.Handle, 0x0115, 1, _vScrollBar.Handle);
//0x0115 for WM_VSCROLL
//1 for SB_LINEDOWN

I'll be grateful for any ideas of how to make it work.
