在Silverlight中使用textbox实现下拉列表

概述 public void GetShow(TextBox txtBox, List<FontFamily> font)         {             Popup p = new Popup();             Border border = new Border();             border.BorderBrush = new SolidColorBrush(

@H_419_9@ public voID GetShow(TextBox txtBox,@R_404_6818@<FontFamily> Font)
        {
            Popup p = new Popup();
            border border = new border();
            border.borderBrush = new SolIDcolorBrush(colors.Blue);
            border.borderThickness = new Thickness(0);@H_419_9@

            StackPanel panel1 = new StackPanel();
            panel1.Background = new SolIDcolorBrush(colors.White);@H_419_9@

            @R_404_6818@Box @R_404_6818@ = new @R_404_6818@Box();            @R_404_6818@.Height = 100;            @R_404_6818@.WIDth = txtBox.WIDth;            @R_404_6818@.ItemsSource = Font;            @R_404_6818@.SelectionChanged += new SelectionChangedEventHandler((sender,e) =>   //添加选择到textBox空间上            {                    txtBox.Text = @R_404_6818@.SelectedItem.ToString();                    panel1.WIDth = txtBox.WIDth;                    if (txtBox.Text != "" || txtBox.Text != null)                        p.IsOpen = false;            });            panel1.Children.Add(@R_404_6818@);            border.Child = panel1;            p.Child = border;            p.VerticalOffset = txtBox.margin.top + txtBox.Height;   //让创建的面板始终都在textBox空间的下方            p.HorizontalOffset =txtBox.margin.left;            p.IsOpen = true;        }@H_419_9@ @H_301_22@ 总结
