I have a ultra web tree view in  the LHS of HTML table cell and ultra web grid in the RHS.

When I click the tree view node, the data of the corresponding table will be queried and displayed on the RHS Grid.

But the entire screen should not post back on the grid contents should change. This is the requirement.

This is a content page inside a master page.

I placed the grid inside WARP and set the triggerID to tree view ID.

But the entire screen postback is happening. WARP effect is not working

Could you please provide the solution for this?
