Hierachical RadGrid-Unable to display the child table using jquery.

[Paul]

I'm working on  a Hierachical RadGrid which is enclosed in an  asp UpdatePanel, and I need to customize it in such a way that - Only the parent rows should be rendered first(the query corresponding to this fetches only the parent rows from the database), and then on the expand button click - the 'Id' corresponding to the row is send via ajax and a different query fetches the child data corresponding to only the selected row.
 Currently I'm invoking an external ajax request through a jquery call from ClientEvents-OnRowClick in the ClientSettings of the grid. Now I'm unable to fill data into the child table from the ajax response using jquery.
Is there an easier way to go about it? That is there an inbuilt function to use 2 different queries to grab the data that populates the Hierachical RadGrid - one to get the parent rows and the other to get the child row corresponding to the parent row that is clicked.

Thanks in advance.

Hi Paul,

In your case the easier way for achieving the required functionality is to simply use the Hierarchical Load Mode ServerOnDemand. This way only detail table-views of the expanded items are rendered and the The roundtrip to the database happens when the grid is bound to get the parent items and when an item is expanded for the children. See the online resources below for more information on this matter:
