Question

好吗？我有一个更新面板内的按钮，单击此按钮我正在尝试加载更新面板更新面板，在此我添加了一个usercontrol。这是动态完成的，没有成功。有谁可以帮助我？

    Protected Sub btnNewRpt_Click(sender As Object, e As EventArgs) Handles btnNewRpt.Click
        Dim hydic As New HybridDictionary From {{"tabId", "tab1"},
                                                {"ucPath", "UCRelatorioNovo.ascx"},
                                                {"ucId", "uc1"}}

        buildControls(hydic)
    End Sub

Private Sub buildControls(ByVal hydic As HybridDictionary)
    Dim uc As UserControl = LoadControl(hydic("ucPath"))
    uc.ID = hydic("ucId")

    Dim tg As New PostBackTrigger With {.ControlID = uc.FindControl("btnLoadOtherUC").UniqueID}

    Dim up As New UpdatePanel With {.ID = "upTest"}
    up.ContentTemplateContainer.Controls.Add(uc)
    up.Triggers.Add(tg)

    Dim tp As New TabPanel With {.ID = hydic("tabId")}
    tp.Controls.Add(up)

    TabContainer1.Controls.Add(tp)
End Sub

错误描述是：找不到ID为“TabContainer1_tab1_upTest”的UpdatePanel。如果它正在动态更新，那么它必须位于另一个UpdatePanel内。

在TabContainer的TabPanel中放置UpdatePanel upTest ，而不是将TabContainer / TabPanel放在 upTest 中，如果你想更新它们，除了更新你的自定义控件之外，你可以只放置自定义控制 upTest 。

UpdatePanel，Trigger PostBack和User Control如何在TabPanel中动态加载
