I have a problem here ;
I've create a treeview in c# like this code ,but
How can I do this in wpf (xaml); ?:confused:


C#
public void PopulateTreeView(  string dirValue, TreeNode parentNode )
     {
        /*   dirValue = inputTextBox.Text
             parentNode = directoryTreeView.Nodes[0] ..
         *
            directoryTreeView is a Treeview
         */


         // array stores all subdirectories in the directory
        string[] directoryArray =  Directory.GetDirectories( dirValue);

        try
        {
           // subdirectories are present
           if ( directoryArray.Length != 0 )
           {
              //  create new TreeNode,

              foreach ( string directory in directoryArray )
              {
                  // substringDirectory is a string defined in generall
          substringDirectory = Path.GetFileNameWithoutExtension(directory );


                  // current directory
                 TreeNode myNode = new TreeNode( substringDirectory );

                 // add current directory node to parent node
                 parentNode.Nodes.Add( myNode );

                 // recursive populate
                 PopulateTreeView( directory, myNode );
              }
           }
        }


        catch ( UnauthorizedAccessException )
        {
           parentNode.Nodes.Add( "Access denied !" );
        }
     }

You can do it pretty much the same way. In fact, the code should pretty much be able to be dropped in exactly the way you already have it (with the appropriate variable name change for the treeview itself).

You can use TreeViewItem class in WPF or else write your output in a XML file and use the same file as the source of TreeView in XAML.
