Hi,

I have WebHierarchicalDataGrids on a page that I would like to export to PDF, when do so, I receive the following error:

Error message: 'C:\ProjectPath' is not a valid virtual path. - /PageName.aspx

Source: 

Class: VirtualPath

Method: Create

Help link: 

Inner exception: System.Web.HttpException: 'C:\ProjectPath' is not a valid virtual path.

The grid and document exporter:

The grid and the document exporter are on the same asp:UpdatePanel
The grid does have a custom pager like the one of the samples (WebDataGrid)
The grid uses a DataSet as DataSource that I rebind on every PostBack.
