如何编辑模态弹出窗口内的gridview？

Question

我有一个gridview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，当点击编辑按钮时modalpopup关闭是由于尽管事实证明我的GridView是一个更新面板完全回发...

我看了看解决方案here和here但没有解决问题。我也尝试过关于ModalPopupExtender与更新面板等的定位的太阳下的每个组合，并尝试将UpdateMode更改为条件。

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> 

代码背后：

Dim sdsLabels As New SqlDataSource 
    sdsLabels.ID = "sdsLabels" 
    sdsLabels.ConnectionString = System.Configuration.ConfigurationManager.AppSettings.Get("Generic Connection String") 
    sdsLabels.ProviderName = "System.Data.SqlClient" 
    sdsLabels.DeleteCommand = "DELETE FROM [JS_LABELS] WHERE [LABELID] = @LabelId" 
    sdsLabels.SelectCommand = "SELECT [LABELID], [CIRCUITNUMBER], [PANELNUMBER], [ADDITIONAL1], [ADDITIONAL2], [ADDITIONAL3] FROM [JS_LABELS] WHERE [QUOTEITEMID] = @QuoteItemId" 
    sdsLabels.UpdateCommand = "UPDATE [JS_LABELS] SET [CIRCUITNUMBER] = @CircuitNumber, [PANELNUMBER] = @PanelNumber, [ADDITIONAL1] = @Additional1, [ADDITIONAL2] = @Additional2, [ADDITIONAL3] = @Additional3 WHERE [LABELID] = @LABELID" 
    sdsLabels.SelectParameters.Add(New Parameter("QuoteItemId", Data.DbType.Int32, e.CommandArgument.ToString())) 
    sdsLabels.DeleteParameters.Add(New Parameter("LabelId", Data.DbType.Int32)) 

    Dim paramCollection As New ParameterCollection 
    paramCollection.Add("CircuitNumber", Data.DbType.String, "") 
    paramCollection.Add("PanelNumber", Data.DbType.String, "") 
    paramCollection.Add("Additional1", Data.DbType.String, "") 
    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()

在我的经验中，ModalPopupExtender将始终紧贴回发，除非你明确地要求它不要在事件触发回邮：

btnSubmitRequest_ModalPopupExtender.Show();
