Hi,

 I am building a treeview by using populateondemand=true option. (i.e. dynamically loading the child nodes when user clicks on parent node).  While building the treeview, i am counting the number of child nodes under a parent node and based on that i am displaying (+) sign before the node.

 I am setting the treeview.selectionaction = TreeNodeSelectAction.None to avoid page postback.

Now, my problem is I am not able to select leaf nodes. But, if I set "TreeNodeSelectAction.Select", then i am able to but with postback.

 My requirement is, without postback i must be able to select the leaf nodes.

 Anybody help me please... it is very urgent..

Thanks in advance

Ganesh
