I have a tree view set up that has a root node called Rss Feeds, parent nodes underneath the root node for example, Programming, then under programming there are leaf nodes that contain an Rss Feed Name and a value containing the URL.
When the user clicks on a leaf node containing the URL, that rss feed is displayed on the screen in a datalist.
Here is where the problem lies: when the user clicks on either the root node or a parent node, there is no url present so I am getting a data binding error. I am setting the Xmldatasource and datalist properties dynamically from the selected node changed event. How can I determine, if the selected node change event is occuring from either a root, parent or leaf node.
