Hi,

Is there a way to trigger a postback from the OnClientNodeExpanding and OnClientNodeCollapsing? The reason is i have 5000 of nodes and had to check for childnodes for every nodes.

Thanks!

Hello Jing,


If you want to fire NodeExpand/NodeCollapse events when expanding/collapsing the node, then set the ExpandMode property of node to "ServerSide".


See the demo: TreeView / Load on Demand Modes
