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 - 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,

Because of the complex nature of the hierarchical structure we have three predefined ways for fetching the data for the parent and all the child levels. These are:

• Client
• ServerBind
• ServerOnDemand

By choosing one of those options you tell RadGrid how to load its data. You could find more about the different types of loading data in this help topic.
