This online demo demonstrates the export to PDF feature of RadGrid. Thus you can transform the data from your web grid in
pdf file and make it 'understandable' among various pdf readers. 
<br />
The approach is very straight-forward - to export the grid content to PDF format simply use the 
ExportToPdf() RadGrid server-side method. You may also need to configure the exporting settings for the grid through the 
<b>RadGrid.ExportSettings</b> section. The available properties are:
<ul>
<li><strong>FileName -</strong> a string specifying the name (without the extension)&nbsp;of the file that will be created. The file extension is automatically added based on the method that is used. </li>
<li><b>ExportOnlyData</b> - determines whether only data will be exported. </li>
<li><b>IgnorePaging</b> - specifies whether all records will be exported or merely those on the current page </li>
<li><b>OpenInNewWindow</b> - open the exported grid in a new instead of the same page</li>
</ul>
There is additional sub-category (<b>Pdf</b>) for the <b>ExportSettings</b> dedicated on various configuration settings
