FindControl手風琴內容ContentTemplate

我有一個手風琴，並在ContentTemplate中放置了下拉列表。我正在使用Accordion1_ItemDataBound將數據表綁定到下拉列表。主要問題是我無法找到下拉列表。FindControl手風琴內容ContentTemplate

<ContentTemplate> 
           <table border="0" width="490px" style="background-color: transparent"> 
            <tr> 
             <td>

            </tr>

我注意到，你如果在這裏面查找調用語句：

if (e.ItemType != AjaxControlToolkit.AccordionItemType.Content)

由於您的DDL是裏面的ContentTemplate也許陳述必須是：

if (e.ItemType == AjaxControlToolkit.AccordionItemType.Content)

如果我將它從！=更改爲==，然後它就沒有進入ID號 – Danny 2012-08-07 14:23:58

你可以顯示你的代碼綁定到手風琴，它可以幫助診斷問題嗎？ – bUKaneer 2012-08-07 14:35:47

保護無效LoadCandidates（） { PDS =新PagedDataSource（）; pds.DataSource = db.GetCandidates（456123，6，「1037」）。DefaultView; pds.AllowPaging = true; pds.PageSize = 10; 如果（SelectedPage>（pds.PageCount - 1）） SelectedPage = pds.PageCount - 1; 如果（SelectedPage <0）{ SelectedPage = 0; } pds.CurrentPageIndex = SelectedPage; Accordion1.DataSource = pds; Accordion1.DataBind（）; } – Danny 2012-08-07 14:37:19
