我在我的 on事件上使用Ajax Accordion了控件，我想设置我在 java 脚本中设置的控件属性。Master PagePage_LoadSelectedIndexAccordion

我的问题是每次HiddenField1.Value = " "Page_Load的值都没有。我没有得到我在 java 脚本中设置的隐藏字段的值，而是得到什么或空字符串。

下面是隐藏字段

<asp:HiddenField ID="HiddenField1" runat="Server"  />

注意：（1）我已经HiddenField完成了我的任务。 (2)我这样做是因为Ajax Accordion在回发后丢失了当前窗格。

<script type="text/javascript">
        function pageLoad()
         {
            $find('<%= UserAccordion.ClientID %>' + '_AccordionExtender').add_selectedIndexChanged(onAccordionPaneChanged); 
        }

       function onAccordionPaneChanged(sender, eventArgs) 
         { 
           var selPane = sender.get_SelectedIndex();
           document.getElementById('<%=HiddenField1.ClientID%>').value = selPane;
           //alert("SelectedIndex:" + selPane  ); This message fires nicely so i have confirmed that this event work
         }
    </script>

.vb以下是我在文件中的后端代码

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If HiddenField1.Value = "" Then
        Else

            UserAccordion.SelectedIndex = HiddenField1.Value

        End If
End Sub

尝试在两个树视图的TreeNodeDataBound事件处理程序中清除节点的 NavigateUrl 属性：

protected void treView_TreeNodeDataBound(object sender, TreeNodeEventArgs e)
{
    e.Node.NavigateUrl = null;
}

我已经解决了这个问题，请参阅我在这篇文章 Ajax Accordion Loses Current Pane上的回答

下面如果链接断开：

Query String我确实通过使用下面的链接来解决这个问题

url="~/Opportunity/Indent.aspx?index=1" // replace 1 with your desired index

在页面加载事件中写这样的东西

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) 

        Dim selectedindex As String = Request.QueryString("index")
        UserAccordion.SelectedIndex = selectedindex



    End Sub

我使用会话变量（即 Accordion.SelectedIndex = Session("AccordionIndex") 但 QueryString 也可以正常工作（除非您想抑制 URL 中的索引，否则会话状态会更好）
