Part of my Word Automation Services project was to provide an alternate save location. WAS takes this in the form of a string [url]. I figured I would start off just by using SPTreeView control and return the selected node [url] back to the parent form.

SPTreeView, unfortunately, sets the NavigateUrl property. When this property is set, the SelectedNodeChanged and TreeNodeCheckChanged events do not fire. So, instead I used a standard TreeView that is similar to the SPTreeView.

            var rootWebNode = new TreeNode(Web.Title, Web.Url, rootIcon) {SelectAction = TreeNodeSelectAction.None};
            treeView1.Nodes.Add(rootWebNode);
