title: Devexpress winform PDFViewer Zoom In and Zoom Out
body: <p>Using PDFViewer1 how would one implement their own zoom-in and zoom-out controls?</p>
  
  <p>I have Zoom-In and Zoom-Out picturebox graphics on my form, that when clicked I want to either zoom in or zoom out respectively.</p>
  
  <p>I program in VB.net using Visual Studio 2012</p>
  
  <p>In my feeble attempt this is what I have:</p>
  
  <pre><code>Private Sub Zoom_In_Click(sender As Object, e As EventArgs) Handles Zoom_In.Click
      Me.PdfViewer1.ZoomMode = PdfZoomMode.Custom
      Me.PdfViewer1.ZoomFactor = 120
      Me.PdfViewer1.Refresh()
  End Sub
  </code></pre>
  
  <p>I would appreciate anyone pointing me in the right direction using either
  VB or C#, thanks for your help.</p>
