treeview SelectedIndexChange problem

[steven shingler]

Hi all

I've a treeview made up of images in a directory structure

When the image name is clicked on in the tree, i'd like to be able to
popup the image in a new window

so far I've got a javascript function to handle my SelectedIndexChange
event:

function returnSelectedIndexCh(){
var str = "";
var index = document.forms(0).all("TreeView1").selectedNodeIndex;
var currentNode = document.forms(0).all("TreeView1").getTreeNode(index);
strLoc += currentNode.getAttribute("Text");
alert(str);
}

this gives me the name of the image, but I need the parent information
too, so I can reference the directory of the image.

I was hoping for currentNode.getAttribute("Parent"), but that was just
one bridge too far.

A client-side solution would be brilliant, so as to avoid postback,
but if anyone can see a server-side solution that would be great too.

Many Thanks for taking a look!
Steven

Hi,

I really understand only a small bit of all the things with the treeview,
but the nodeindex, so far I think, would help. The nodeindex is a string
like "1.2.3.4", so if you are at the bottom, you know, that "1.2.3" is your
parent.

Hope, this helps.
Best regards,

Hi Manfred, thanks for replying
whilst looking at the nodeindex, I found you can get the Parent attribute like this:

var tree = window.event.srcElement
var nodeIndex = tree.clickedNodeIndex;
var node = tree.getTreeNode(nodeIndex);
var parent = node.getParent().getParent().getParent().getAttribute("Text");

which is quite cool too!
