Export multiple Rad Grids to single PDF

I am using telerik controls on my aspx page. I have around 7 Rad Grids(similar to GridView) on my page. Now, telerik has one step export to pdf opt开发者_运维知识库ions for rad grid's. But this is for exporting individual rad grid's. I want to export the data in all rad grid's to 1 pdf file. Telerik has solution for this mentioned on their support page. But it asks to include 1 rad grid that encapsulates these 7 radgrids and then export that single radgrid to pdf.

But all of my 7 rad grids have different data sources. When i wrap my rad grids into one single rad grid, i cannot access the inner radgrids in c#.

Can someone suggest some solutions that I can try?

Thankyou, Ghanshyam.

There was a similar question (about PDF export). Maybe the product mentioned in one of the answers might help you:
