Hi,
I am looking for moving a zoomed in page using arrow keys(keyboard) inside GDViewer WPF, can we achieve it, or any suggestion/existing ways to go forward.
Thanks and Regards,
Abin Mathew.

Hello,
Maybe this code snippet can be useful:
Code: Select all
Private Sub GdViewer1_KeyDownControl(ByVal sender As Object, ByVal e As AxGdViewerPro4.__GdViewer_KeyDownControlEvent) Handles GdViewer1.KeyDownControl
Select Case e.keyAscii
Case 38
Me.GdViewer1.SetVScrollBarPosition((Me.GdViewer1.GetVScrollBarPosition() - 20))
Case 40
Me.GdViewer1.SetVScrollBarPosition((Me.GdViewer1.GetVScrollBarPosition() + 20))
Case 37
Me.GdViewer1.SetHScrollBarPosition((Me.GdViewer1.GetHScrollBarPosition() - 20))
Case 39
Me.GdViewer1.SetHScrollBarPosition((Me.GdViewer1.GetHScrollBarPosition() + 20))
End Select
End Sub
