应该为特定的树视图节点打开asp更新面板

Question

我还有一个问题。 我有3个选项卡面板，每种类型的功能。所有包含不同功能的树视图，用于不同的功能。

<div Class="divopt">

   <cc1:TabContainer runat="server" CssClass="leftspace">
       <cc1:TabPanel ID="addpaneltab" runat="server" HeaderText="Add" >
           <ContentTemplate>

               <asp:LinkButton runat="server" Text="Add Institutes" ID="AddInstitutes" OnClientClick="displayPopup(); return false;"></asp:LinkButton>
               <asp:TreeView ID="TreeMenuView1" runat="server" OnSelectedNodeChanged="TreeMenuView1_SelectedNodeChanged" NodeStyle-NodeSpacing="5px" CssClass="leftspace" ToolTip="Add new Details">

            </asp:TreeView>
           </ContentTemplate>
       </cc1:TabPanel>
       <cc1:TabPanel runat="server" ID="editpaneltab" HeaderText="Edit">
           <ContentTemplate>
           <asp:TreeView ID="TreeViewEdit" runat="server" OnSelectedNodeChanged="TreeViewEdit_SelectedNodeChanged" NodeStyle-NodeSpacing="5px" CssClass="leftspace" >

            </asp:TreeView>
               </ContentTemplate>
       </cc1:TabPanel>
       <cc1:TabPanel runat="server" ID="deletepaneltab" HeaderText="Delete">
           <ContentTemplate>
           <asp:TreeView ID="TreeViewDelete" runat="server" OnSelectedNodeChanged="TreeViewDelete_SelectedNodeChanged" NodeStyle-NodeSpacing="5px" CssClass="leftspace" >

            </asp:TreeView>
               </ContentTemplate>
       </cc1:TabPanel>
   </cc1:TabContainer>
   </div>

在addpaneltab中选择节点时。我正在打开一个更新面板。 现在问题是如果我点击该面板中的节点，更新面板也会打开其他2面板选项卡。 我打开更新面板的代码是 -

 protected void TreeMenuView1_SelectedNodeChanged(object sender, EventArgs e)
    {

        instext.Text = TreeMenuView1.SelectedValue;
        int level = TreeMenuView1.SelectedNode.Depth;
        if(level==0)
        {

            idGrade.Style.Add("display", "block");
            idCamera.Style.Add("display", "none");
            idClass.Style.Add("display", "none");
        }
        else if (level==1)
        {
            TextGrade.Text = TreeMenuView1.SelectedValue;
            idClass.Style.Add("display", "block");
            idGrade.Style.Add("display", "none");
            idCamera.Style.Add("display", "none");
        }
        else
        {
            idCamera.Style.Add("display", "block");
            idClass.Style.Add("display", "none");
            idGrade.Style.Add("display", "none");
        }

    }

idgrade，idclass，idcamera是创建updatepanel的DIV。
