Hi all,
I'm trying to use ObjectDataSources for each level of a RadGrid Hierarchy view, almost exactly like the AccessDataSources are listed in the sample on the web site that shows the customer - order - order details in an expandable hierarchy view. I think I'm close to getting it working, but no matter what I put in the SelectParameters the value I get in the SelectParameter function is 0. (In other words, I have the ObjectDataSource that handles getting the data for the children of the top-level items taking a parameter to represent the item that was expanded. However, I can't tell what item was expanded and therefore cannot tell which children to get.) Has anyone else run into this problem? What am I doing wrong?
Thanks,
Scott

You must specify the foreign keys that get passed down from the parent table as <asp:SessionParameters>, they also must have the same name and session name. Also, they need to exist in DataKeyNames property
It happens automagically =)
