ManualSmartCallbacks Errors out
posted

I have a WebTree wrapped in a WebAsyncRefresh Panel, when the

LoadOnDemand property is set to Manual everything works fine however if i set it to ManualSmartCallbacks once it triggeres the

DemandLoad it passes null as

WebTreeNodeEventArgs parameter! which causes an error.

 Why is that Manual works but ManualSmartCallbacks  does not work?

 Thanks,

    I just want to add one additional link to a forum thread that discusses this scenario in detail - UltraWebTree inside WARP with various modes of load on demand:

    http://forums.infragistics.com/forums/t/10854.aspx 

    So basically, you need to choose one of the modes (either WARP with Manual loadondemand or ManualSmartCallBacks) - since there are limitation for each mode. More info can be found in the forum link above and in the DevCenter article that I've cross-linked from there.

    Hope this help.
