LoadOnDemand.ManualSmartCallbacks help !!!!!

Ganesh posted over 15 years ago

Hi,

I'm using LoadOnDemand.ManualSmartCallbacks in UltraWebTree to add nodes

dynamically on DemandLoad event.

Everything working fine, but on postback all the nodes getting cleared.

How to retain all those datas on postback ????

This is correct behavior. WebTree does not "remember" previously-loaded nodes when using ManualSmartCallbacks or AutomaticSmartCallbacks.

The best option is to use the "Manual" load on demand style instead. You can provide AJAX functionality to this setup by placing WebTree inside of a WebAsyncRefreshPanel (WARP) or an UpdatePanel. Once nodes are loaded in this setup, they remain loaded through postbacks.
