Question

is it possible from c# to add some groups, buttons,… to excel-2007’s print preview ribbon… why? i wanted to put some images on that ribbon so that user by selecting the image will be able to put it on a sheet (where ever on that sheet by dragging it) and print it with that sheet…
many thanks!

You do this the same way you add a group to any existing excel ribbon tab.

Create a VSTO add-in project and add a Ribbon XML class.

Inside the ribbon.xml file, this will give you a group with one button on the print preview tab:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" onLoad="Ribbon_Load">
  <ribbon>
    <tabs>
      <tab idMso="TabPrintPreview">
        <group id="MyGroup"
               label="My Group">
          <button id="Test" label="Test"/>
        </group>
      </tab>
    </tabs>
  </ribbon>
</customUI>
