我在 ModalPopupExtender 中有一个详细信息视图，它运行良好。在详细信息视图的页脚模板部分中，我放置了几个链接按钮。

当按下链接按钮时，它应该触发动态创建的 CollapsiblePanelExtender。到目前为止，一切正常。下面是modalpopup里面detailsview的一部分

<Toolkit:ModalPopupExtender ID="mdlPopup" runat="server" TargetControlID="btnShowPopup" 
    PopupControlID="pnlPopUp" BackgroundCssClass="modalBackground" 
    PopupDragHandleControlID="DragHandle"  DropShadow="true"/>
<asp:Panel ID="pnlPopUp" runat="server" style="display:none;" 
    CssClass="popUpStyle">
    <asp:Panel ID="DragHandle" runat="server" CssClass="drag" ></asp:Panel>
    <asp:DetailsView ID="dvwDetailsUser" runat="server"  
         AutoGenerateRows="False" 
         Width="100%" 
         onitemcommand="dvwDetailsUser_ItemCommand" 
         FooterStyle-HorizontalAlign="Right"  
         ForeColor="#990000" 
         BorderWidth="0px" >                   
         <Fields>
          <asp:BoundField DataField="GivenName" HeaderText="First name" />
          <asp:BoundField DataField="SurName" HeaderText="Last name" />
          <asp:BoundField DataField="DisplayName"  HeaderText="DisplayName" />
          <asp:BoundField DataField="SamAccountName"  HeaderText="Account" />
          <asp:BoundField DataField="EmailAddress" HeaderText="E-mail" />
          <asp:CheckBoxField DataField="Enabled" HeaderText="user enabled" />
          <asp:BoundField NullDisplayText="" />
          <asp:BoundField DataField="DistinguishedName" 
              HeaderText="DistinguishedName" />
         </Fields> 
         <FooterStyle HorizontalAlign="Right" />
            <FooterTemplate >
               <asp:LinkButton ID="btnProperties" 
           runat="server" CommandName="Remove" Text="Remove" />
            </FooterTemplate>
            <HeaderStyle BackColor="#FFCD4A" Font-Bold="True" 
             HorizontalAlign="left" />
            <AlternatingRowStyle BackColor="#EFEFEF" />
    </asp:DetailsView>
</asp:Panel>

modalpopup 扩展器和详细信息视图包含在更新面板中。当我在弹出窗口中按下链接按钮时，将显示可折叠面板。

在可折叠面板内，我还动态创建了按钮。当我按下按钮时，不会触发附加到按钮的新事件处理程序。

protected void dvwDetailsUser_ItemCommand(object sender, DetailsViewCommandEventArgs e)
{
   if (e.CommandName == "Remove")
        DeleteAccount();
   end if
}

public void DeleteAccount()
{

    Panel p = new Panel();
    Button btnRemove = new Button();

    p.ID = "pnlDeleteAccount";
    p.GroupingText = "Remove" + dvwDetailsUser.Rows[2].Cells[1].Text;

    btnRemove.Text = "Remove"
    btnRemove.ID = "Apply";
    btnRemove.CausesValidation = false;

    btnRemove.UseSubmitBehavior = false;
    btnRemove.Click += new EventHandler(btnRemove_Click);
    p.Controls.Add(btnRemove);

    CollapsiblePanelExtender cpe = new CollapsiblePanelExtender();

        cpe.TargetControlID = p.UniqueID;
        cpe.ExpandControlID = p.UniqueID;
        cpe.CollapseControlID = p.UniqueID;
        cpe.AutoCollapse = false;
        cpe.AutoExpand = false;
        cpe.ScrollContents = false;
        cpe.SuppressPostBack = false;
        cpe.ExpandDirection = CollapsiblePanelExpandDirection.Vertical;
        cpe.Page = this.Page;

        pnlPopUp.Controls.Add(cpe);
        cpe.Controls.Add(p);


    mdlPopup.Show();
 }

public void btnRemove_Click(object sender, EventArgs e)
{
    Response.Redirect("UserAccount.aspx");
}

我放置了一个 response.redirect 以查看按下删除按钮时是否会触发事件 btnRemove_click。

我在这里错过了什么吗？
