Multiple spins on TreeNode click (Load On Demand)

[Puneet Minhas]

Hi,

We have a RadTreeView which is loaded on demand. The expand mode for the nodes is set to ServerSideCallBack.
Everything is working fine except that when the user clicks on the '+' sign (node expand) multiple times and too rapidly, there are multiple spins that come up on that node. Once the node expand is complete, all of them go except for one which keeps rotating endlessly (LoadingStatusPosition is set to 'BeforeNodeText').

Could anyone please suggest how to handle this issue?

Thanks & Regards,
Puneet

Thanks for the reply.
It helped me handle the condition.
1 drawback of the approach mentioned in the article is that, no other node can be expanded simultaneously.
Handled this by creating a hashtable and putting and removing node text on onclientnodeexpanding and onclientnodepopulated events respectively.

Thanks,
Puneet
