When I hardcode a TreeView's nodes, I have the option of making folders collapsed automatically.  Is there a way to do this while using a sitemap and tell folders to be collapsed by default when the page loads?

Hi,

There is an ExpandDepth property in the ASP.Net TreeView Contro, its default value is FullyExpand.

If you want the TreeView collapsed when the page load, you can set the TreeView's ExpandDepth  is 0.

Hope it helps.

Hi,

mldesanctis:

I see that option, but I want to pick and choose which folders are open by content, not by depth.

The TreeNode has an Expand method, which can expand the TreeNode,

for example:

 if (node.ChildNodes.Count != 0)
        {
            foreach (TreeNode tn in node.ChildNodes)
            {
                if (tn.Text == strTitle)
                {
                    tn.Expand();
                }
                else if (tn.ChildNodes.Count != 0)
                {
                    foreach (TreeNode tnNode in tn.ChildNodes)
                    {
                        retriverNode(tnNode, strTitle);
                    }
                }
            }
        }

Hope it helps.
