How to Prevent Postback on Expand/Contract

[WombatEd]

I have a two-level RadGrid and I want it to expand and contract the lower level without postback.

Can anyone point me in the right direction.

Helllo,

Set the GridTableView.HierarchyLoadMode property to Client. In HierarchyLoadMode.Client mode, the roundtrip to the database happens only when grid is bound and thereby no postback to the server is needed to expand an item.

Checkout the topic - Hierarchy load modes.

Clarification: In my two-level hierarchy, setting GridTableView.HierarchyLoadMode=true did not work.

Setting MasterTableView.HierarchyLoadMode=true did work.
