Hi,
I am trying to display data in a hierarchical grid. But after clicking on the expand link aginst teh master grid record, the hierarchical grid fails to expand. The event is successfully transferred to DetailTableDataBind event handler. Can I know what I am missing here?

<ExpandCollapseColumn Visible="True">

Is tehr anything else I need to do? What is the code snippet to forcibly expand the grid DetailTableDataBind event handler?
Thanks

Hi Phani,
Depending on the given information I suppose that the grid is not bound correctly when the levels are expanded. To get working hierarchy functionality you need to use advanced data-binding. When binding each detail table view, RadGrid fires the DetailTableDataBind event. The argument for a DetailTableDataBind event handler carries all the information you need for binding the detail table, including the table view that should be bound, its parent item, and so on.
Additionally, I will suggest you examine this online demo and describe what the difference in your implementation.

Hi,
I am doing the binding at the Design time. So that doesn't seem to be the proble. One thing I forgot to add is that I am using a custom Grid, derived from the RadGrid. And within this custom grid I am trying to show the detail grid. Whereas this functionality works fine with the RadGrid, it doesn't work with teh custom Radgrid.
Are there any other things I should look at when using hierarchical grids in a custom RadGrid?
Thanks

Hi Phani,
Based on the supplied information, it is hard to determine what is causing the hierarchical grid not expanding. In order to investigate the problem further, it will be best if you open a formal support ticket, and provide a small working project, which can be tested locally, in order to supply further information.
