[Solved] SEOPagingQueryStringKey not working with other QueryString values

[Nate Pinchot]

Hello,
I am attempting to use SEOPagingQueryStringKey on the RadGrid but whenever I enable SEO Paging my grid says that there are no records whenever the SEOPagingQueryStringKey appears in the URL. If I use SEOPagingQueryStringKey on the MasterTableView it works. I don't get it? I am using this incorrectly?
I am using the latest version (Q3 2008) of the controls.
I am using the OnNeedDataSource event to populate the results of the grid through codebehind from an OracleDataReader.
Again it works fine if I set the SEOPagingQueryStringKey and EnableSEOPaging on the PagerStyle of the MasterTableView just not if I set it on the RadGrid.
The only reason I posted this is because I spent a few hours ripping my hair out trying to figure out what I was doing wrong.
Thanks
Nate

PS. I meant to mention in my first post that the SEOPagingQueryStringKey and EnableSEOPaging work fine on the RadGrid whenever there are not other QueryString values. It is when other QueryString values are introduced that it breaks the population of the grid.
