如何动态给TreeView添加treeViewItem？必须是带图片的

Question

            TreeViewItem item = new TreeViewItem();
            item.Header = "推荐";
            item.Style = (System.Windows.Style)FindResource("treeControl"); 
             Parent.Items.Add(item); 新加的这个节点必须是带图片的。 不知道图片怎么动态加进去。

Answer 1

使用
BitmapImage bitmap = new BitmapImage();
            bitmap.BeginInit();
            bitmap.UriSource = new Uri(@"");
            bitmap.EndInit();http://topic.csdn.net/u/20100611/09/167386DA-ECFC-48CF-A2E6-E0F643CBB322.html

搞定了            DockPanel dp = new DockPanel();
            TextBlock tb = new TextBlock();
            tb.Text = "推荐";
            tb.VerticalAlignment = VerticalAlignment.Center;
            System.Windows.Controls.Image img = new System.Windows.Controls.Image();
            img.Stretch = Stretch.None;
            img.Source = new BitmapImage(new Uri("treeviewChild.png", UriKind.Relative));
            dp.Children.Add(img);
            dp.Children.Add(tb);            TreeViewItem item = new TreeViewItem();
            item.Header = dp;
            item.Style = (System.Windows.Style)FindResource("treeControl"); 
            Parent.Items.Add(item);
