I can use C1PrintPreviewControl1.PreviewPane.DoGoPreviousPage and C1PrintPreviewControl1.PreviewPane.DoGoNextPage to jump page in preview with my vb code. But I cannot find any method that like DoGoFirstPage or DoGoLastPage to jump to first or last page. Is there anybody can help me to figure out the proper method that can lead preview to first and last page?. Thank in advance.
