Hi..this is working to suppress the expand event and for avoiding postback

But when i try to select any child node an exception is being thrown.It says

The node at index 0.0 is not currently displayed in the tree. SelectedNodeIndex cannot be set to an undisplayed node .

Can some one help me ???..Thanks in advance!!!

You need to override the events and point them to JS methods.

In the aspx page add this JS method, assuming your treeview object is called treeView.

function myFunc()

{

}

</script>

function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { } function myFunc() { }

Then in Page_Load add the following:

treeView.Attributes.Add("onexpand","javascript:myFunc()");

treeView.Attributes.Add("oncollapse","javascript:myFunc()");

This should let you expand and collapse client side with no round trips.

I'm really waiting an answer for this question too. Postback on -/+ doesn't make any sense.

Please share if you fand a solution. Updating treeview.htc file didn't work for me and I tried to catch onexpand and oncollapse events from javascript. I did it but how can I make TreeView expand and collapse ?

This is the whole story...

Treeview control's selectednodeindex property in javascript

sphatak — Fri, 02 Dec 2005 21:10:16 GMT

I am trying to get the selectednodeindex property of the Microsoft Treeview webcontrol but having no luck. I am getting an error "undefined". Does that mean I cannot access this property using javascript? I want it in javascript to avoid postback. Is it possible to get the index of the node selected or the text selected in any other way on the client side?

Here is my javascript code snippet: alert(document.all.iform.TreeViewCtrl.SelectedNodeIndex)

Any help with me highly appreciated!

Thanks.
