当选择gridview行/ ASP/AJAX/C时，Modal Popup关闭＃

Question

我有一个Modal Popup，在GridView内部从LinkButton启动。 Modal Popup内有3 TextBox和3 GridView。用户从GridView行中选择项目，然后将其填充到文本框内。

当用户选择GridView行时，模式弹出窗口关闭。如果再次打开模式弹出框，则会填充TextBox，但我需要模态弹出框保持打开状态。

首页的GridView

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> 
</asp:ScriptManager> 
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
    <ContentTemplate> 
     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" 
      OnSelectedIndexChanged="GridView1_SelectedIndexChanged" 
      OnRowDataBound="GridView1_RowDataBound" CssClass="mGrid" 
      AlternatingRowStyle-CssClass="alt"> 
      <Columns> 
       <asp:BoundField DataField="Name" HeaderText="Name" 
        HtmlEncode="true" /> 
       <asp:BoundField DataField="Order" HeaderText="Order" 
        HtmlEncode="true" /> 
       <asp:BoundField DataField="Drinks" HeaderText="Drinks" 
        HtmlEncode="true" /> 
       <asp:BoundField DataField="Comments" HeaderText="Comments" 
        HtmlEncode="true" /> 
       <asp:CommandField ShowSelectButton="true" ButtonType="Link" 
        Visible="false" SelectText="Enroll" /> 
       <asp:TemplateField ItemStyle-Width="60px"> 
        <ItemTemplate> 
         <asp:LinkButton ID="lnkEdit" runat="server" 
          Text="Add Lunch" OnClick="Edit"/> 
        </ItemTemplate> 
       </asp:TemplateField> 
      </Columns> 
     </asp:GridView> 
    </ContentTemplate> 
</asp:UpdatePanel> 

首页模式弹出

     </tr> 
     <tr> 
      <td> 
       <div class="popup_Buttons"> 
        <asp:Button ID="Okaybtn" runat="server" Text="Done" 
         OnClick="Save" /> 
        <input id="Button1" type="button" value="Cancel" /> 
       </div> 
      </td> 
     </tr> 
    </table>

<cc1:ModalPopupExtender ID="popup" runat="server" DropShadow="false" 
    PopupControlID="Panel2" TargetControlID="btnShowPopup" 
    BackgroundCssClass="modalBackground"> 
</cc1:ModalPopupExtender> 

任何人都可以阐明为什么发生这种情况和我能做些什么来解决它的一些光？ 让我知道，如果你需要看到一些代码隐藏。

在此先感谢！

有点晚了，但你可以拨打电话

modalPopupExpander.Show（）;

可能的方法是注册您的模态内容页面的事件。
