asp.net – 从标签容器中的数据绑定gridview丢失更新面板触发器

<ajaxToolkit:TabContainer runat="server" ID="tabBody">     
    <ajaxToolkit:TabPanel runat="server" ID="tabPanel1">
      <ContentTemplate>
        <asp:UpdatePanel runat="server" ID="updPanel1">
          <ContentTemplate>
            <asp:Gridview runat="server" ID="grd1" OnRowCommand="grd1_RowCommand" OnRowDataBound="grd1_RowDataBound">
                <asp:TemplateField>
                  <ItemTemplate>
                     <asp:LinkButton ID="lnkChangePanels" runat="server" CommandArgument='<%#Eval("id") %>' CommandName="gotopanel2" Text='<%#Eval("FirstName") & " " & Eval("LastName")%>' /> 
                  </ItemTemplate>
               </asp:TemplateField>
            </asp:Gridview>
          </ContentTemplate>
        </asp:UpdatePanel>
      </ContentTemplate>
    </ajaxToolkit:TabPanel>
    <ajaxToolkit:TabPanel runat="server" ID="tabPanel2">
      <ContentTemplate>
        <asp:UpdatePanel runat="server" ID="updPanel2">
          <ContentTemplate>
            <asp:Gridview runat="server" ID="grd2">

            </asp:Gridview>
          </ContentTemplate>
        </asp:UpdatePanel>
      </ContentTemplate>
    </ajaxToolkit:TabPanel>
 </ajaxToolkit:TabContainer>

为了填充面板1上的gridview,有一个用户输入的搜索框,我调用一个函数将linq查询绑定到它.

现在我将rowcommand添加为rowdatabound上的回发触发器：

Protected Sub grd1_RowDataBound(ByVal sender As Object,ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim lb As LinkButton = CType(e.Row.FindControl("lnkChangePanels"),LinkButton)
            If Not lb Is Nothing Then
                ToolkitScriptManager1.RegisterPostBackControl(lb)
            End If
        End If
    End Sub

然后这是我必须触发选项卡面板更改(并做一些其他的东西)的代码：

Protected Sub grd1_RowCommand(ByVal sender As Object,ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles grd1.RowCommand
    Dim id = e.CommandArgument.ToString()
    Select Case e.CommandName
       Case "gotopanel2"
            eventDetails(id,"C")
            tabBody.ActiveTab = tabPanel2
    End Select
End Sub

这会导致正确的回发并更改选项卡,一切都按预期工作.但是如果我回到第一个标签并尝试点击gridview 1中的另一行,则没有任何反应.

有没有办法构建这个,以便选项卡可以更改而不会丢失回发触发器或我是否会发生这种错误？

谢谢.
