Silverlight 4.0 Accordion 解決ScrollViewer 的問題

Silverlight 4.0 開發中，使用Accordion ，在Accordion 中動態添加AccordionItem ，可以設定AccordionItem 的個數，但很難解決ScrollViewer的問題 ，即外框出現捲軸的問題

查了幾個國外的網站都沒有解決辦法！~經常會碰到許多奇怪的問題！~在這裡分析下我的解決方案！~

          <ScrollViewer Margin="0" Grid.Row="1">
                            <toolkit:Accordion Grid.Row="1" SelectionChanged="UserAcc_SelectionChanged" Name="UserAcc" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  AccordionButtonStyle="{StaticResource AccordionButtonStyle1}">
                            </toolkit:Accordion>
            </ScrollViewer>

在Accordion 外套一個ScrollViewer ，添加SelectionChanged的方法

 

        /// <summary>
        /// 擷取所選擇，主要處理Accordion的高度和AccordionItem的高度
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void UserAcc_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            try
            {
                AccordionItem tem = this.UserAcc.SelectedItem as AccordionItem;
                if (null != tem)
                {
                    ///根據AccordionItem 的個數來設定高度
                    this.UserAcc.Height = 600 + this.UserAcc.Items.Count * 32;//600,32 這兩個數字是根據頁面設計實際大大小來定的
                    tem.MaxHeight = 610;//設定最大高度，解決內部出現空白的BUG
                    // tem.ContentTargetSize 可以測試內部的實際高度
                    tem.UpdateLayout();
                }
                else
                {
                    if (this.UserAcc.Items.Count < 15)
                    {
                        this.UserAcc.Height = 500;
                    }
                    else
                    {
                        this.UserAcc.Height = this.UserAcc.Items.Count * 32 + 50;
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
