we have hierarchical radgrid where on expansion of main grid it expands and shows a detail table. each detail table will have multiple records of either type A or Type B. we need to show only one record of type A and one record type B on page load.
The first column of detail table will have an expand button, on click of this it should display all type A rows from client side, and on click of that button it should hide all those rows.
I don't want 3 level hierarchy. since the hidden rows and row with expand button belongs to same level
