Hi Amiram,

Does the above code work for the Webdatatree control having the Infragistics v13.1? If not can you provide a snippet of code that works for the current version of Webdatatree control.

Thanks Amiram.  Your code worked well.  Here's my DataBound event to select a node and open it.  This is using a SiteMapDataSource (but that doesn't really matter).

protected void navTree_DataBound(object sender, EventArgs e)
	{
		//select the current node in the tree
		//BTW, NodeBound happens before DataBound

		var currentUrl = Page.Request.Url.PathAndQuery;

		foreach (DataTreeNode node in ((WebDataTree)sender).AllNodes)
		{
			if (node.NavigateUrl == currentUrl)
			{
				node.DataTree.SelectedNodes.Clear();

				node.Selected = true;
				node.Expanded = true;
				node.ExpandAnscestors();

				break; //get out of this foreach loop
			}
		}
	}

It doesn't work. I tried both ExpandAncestors and Expanded = true in the NodeClick event and in PreRender and the tree always return back to its initial state. Even if it worked, it is not enough because a user can click on any page link to get to another page or write down the url himself, and you won't get any event.

I added this in the DataBound event and it worked:

var url = Page.Request.Url.AbsolutePath;

            foreach (DataTreeNode node in AllNodes)

            {

                if (node.NavigateUrl == url)

                {

                    node.Expanded = true;

                    node.ExpandAnscestors();

                }

            }

By the way, tree.AllNodes is an ArrayList. Is there a reason it is not List<DataTreeNode>?

As far as I know, this control wasn't even exist in the 1.1 framework.

Version 10.1, fix 2039, VS 2010, .NET 4.

how can i determine the node that was selected or clicked?  i see where i can expand based of a node key or text, couldn't figure out how to determine the key and my text value wasn't working.
