Get all parents of a Treeviewitem for a file browser

06-26-2009 6:09 PM |

I went through Justin's tutorial about the TreeViewControl found here:

http://silverlight.net/blogs/justinangel/archive/2008/11/18/silverlight-toolkit-treeview-treeviewitem-amp-hierarchaldatatemplate.aspx

I thought that I should use a modified version of the last part in the tutorial so that I can use the treeview for a file browser on the server. The thing is I need to get the file path whenever I click on a TreeViewItem (which will be a directory or file) in the treeview and to do that I must get all the parents of the node I just clicked, right? So, how can I loop through all parents of that treeViewItem so I can get the path?

If there is a better way to do this I'm open for suggestions.

Thanks!

I solved it myself. I made a recursive method that looked like this:

private void GetTreeViewHeader(TreeViewItem expanded)
        {
            TreeViewItem parent;

            if (expanded.Parent is TreeViewItem)
            {
                parent = (TreeViewItem)expanded.Parent;
                invertedPath += parent.Header.ToString() + "#";

                GetTreeViewHeader(parent);
            }
        }

In this way I get the file path inverted but it's easy to invert it to the real format by just splitting the string and putting it together backwards.
