Disabling postback on TreeView nodes when expanding / collapsing

Question

as?

I tried AutoPostback=false, but clicking on node still sends the page back. Any ideas?

Answer 1

Farther...

The operation of automatic selection for each node is SelectExpand, the “Select” part of this enumeration is interpreted as “I have selected something and you need to send it back”. To simply “expand” a node without causing a postback:

TreeView1.Nodes (0) .SelectAction = TreeNodeSelectAction.Expand
