Sorry that currently paging is only available on root table (parent table) level only.

There is a new feature introduced in WebGrid 7. WebGrid 7 now supports group row paging when used together with VirtualLoad™ mode. The group row paging significantly improves overall performance by loading only a small number of records (specified in GroupRowPageSize property) when user expands the group header.

For more detail information about this new feature, please check the information about this new feature in http://intersoftpt.wordpress.com/2010/02/10/virtual-group-paging-with-client-binding-in-depth/; and the sample in http://live.intersoftpt.com/cs/WebGrid/ClientBinding_VirtualGroupPaging.aspx.

Hope this helps.

How do I request this as a new product feature?

Thank you for your valuable feedback about paging feature on child table in hierarchical WebGrid.

I have forwarded your feature request to WebGrid development team. A work item has been submitted, task #629, regarding this feature request. The dev team will check the feasibility to implement this feature on the upcoming build of WebGrid 7.

I’ll keep you updated with any news I heard from the team regarding this work item number.
