Hello,

Very new at this. 

I am using sitemap binding on the treeview, how do I retain the node that was selected after postback? Do I need to use ajax binding instead?

Thanks.

More searching yielded the following link which tells me how, but I'm unsure on the .BindTo property since I am using the sitemap.  My BindTo looks like this:

.BindTo(

"Web")

I think I'm getting closer, but this isn't working:

.BindTo(

"Web", (item, siteMapNode) =>
{
item.Expanded = ((
string[])ViewData["ExpandedNodes"]).Contains(item.Text);
})
