如何在模式弹出窗口内编辑网格视图？

Question

我有一个网格视图，它出现在动态生成的模式弹出窗口中，并绑定到动态生成的 SqlDataSource。

我这样做是希望利用 gridview 的自动编辑功能。

我的问题是，当单击编辑按钮时，尽管我的 gridview 位于更新面板中，但由于完整的回发，modalpopup 会关闭...

我查看了here 和here 的解决方案，但都没有解决问题。我还尝试了关于 ModalPopupExtender 相对于更新面板等的定位的所有组合，并尝试将 UpdateMode 更改为有条件的。

标记：

<span class="none"><asp:Button ID="btnDummy" runat="server" Text="Dummy" /></span>
<ajax:ModalPopupExtender ID="mpLabel" runat="server" TargetControlID="btnDummy" BackgroundCssClass="modalBackground" PopupControlID="pnlLabels"></ajax:ModalPopupExtender>
<asp:Panel ID="pnlLabels" DefaultButton="btnOk" Style="display:none;" runat="server">    
<div style="background-color:#fff;border:1px solid black;padding:7px;">                
<asp:UpdatePanel ID="upLabels" runat="server" ChildrenAsTriggers="true" EnableViewState="true" UpdateMode="Always">
    <ContentTemplate>
                <asp:Panel ID="pnlGv" runat="server" style="max-height:420px;width:700px;border-bottom:1px #ccc solid;" ScrollBars="Vertical">
                    <asp:PlaceHolder ID="phLabelInfo" runat="server"></asp:PlaceHolder>                    
                    <asp:PlaceHolder ID="phSDS" runat="server"></asp:PlaceHolder>    
                </asp:Panel>                                
    </ContentTemplate>        
</asp:UpdatePanel>
<asp:Button ID="btnOk" runat="server" Text="Ok" />
</div>
</asp:Panel>

    paramCollection.Add("Additional2", Data.DbType.String, "")
    paramCollection.Add("Additional3", Data.DbType.String, "")
    paramCollection.Add("LabelId", Data.DbType.Int32, "0")


    Dim ph As New PlaceHolder
    ph = CType(PageHelper.RecursiveFindControl(Page, "phSDS"), PlaceHolder)
    ph.Controls.Add(sdsLabels)

    Dim gv As New GridView
    ph = CType(PageHelper.RecursiveFindControl(Page, "phLabelInfo"), PlaceHolder)
    ph.Controls.Add(gv)

    gv.CssClass = "LabelsTable"
    Dim LabelId() As String = {"LabelId"}
    gv.DataKeyNames = LabelId
    gv.EnableViewState = True
    gv.AutoGenerateEditButton = True
    AddHandler gv.RowCommand, AddressOf gv_rowCommand
    gv.DataSourceID = sdsLabels.ID
    gv.DataBind()

    mpLabel.Show()

根据我的经验，ModalPopupExtender 将始终在回发时关闭，除非您在回发触发的事件中明确要求不要这样做：

    btnSubmitRequest_ModalPopupExtender.Show();
