ModalPopupExtender隐藏时，下拉后发回的工作

本文关键字：工作 隐藏 ModalPopupExtender | 更新日期: 2023-09-27 18:06:35

我有一个模型弹出扩展器，在这个弹出框中，我有一个AutopostBack="True"的下拉列表。现在，当我选择一个下拉值ModalPopupExtender隐藏。让我知道原因??有人更喜欢更新面板，但问题仍然存在

我的弹出控件是，

  <cc1:ToolkitScriptManager runat="server" ID="ToolkitScriptManager1" EnableScriptGlobalization="true"></cc1:ToolkitScriptManager>            
  <asp:HiddenField ID="HiddenField1" runat="server" />
  <cc1:ModalPopupExtender ID="ModalPopupExtender3" runat="server" 
  BehaviorID="modalPopupExtender3" 
  TargetControlID="HiddenField1"
  OkControlID="cancel1" 
  BackgroundCssClass="modalPopup" >
  </cc1:ModalPopupExtender> 
 <!-- Update section-->
  <div id="updatdediv1" visible="false" >
  <div class="portlet box blue" id="Div3">

    <div class="controls">

   <asp:Button ID="btnedit2" runat="server" Text="Submit"  CssClass="btn blue"  ValidationGroup="grp1"   />     
                            &nbsp;&nbsp;

 </div>
 </div>
 </div>
 </div>
  <!-- temp panel-->                                        
  <asp:Panel ID="kj" runat="server"  >
  <table  >
  <tr><td class="style9">
  <table >
  <tr> <td class="style8"> &nbsp;</td>     </tr>
  <tr >
  <td align="left" class="style12">
   <asp:Button ID="cancel1" runat="server"  Text="Cancel" Style=" display:none"

ModalPopupExtender隐藏时，下拉后发回的工作

如果您需要模态弹出式扩展程序"存活"回发，那么您将不得不自己管理。处理下拉菜单的SelectedIndexChanged事件，并在那里显示弹出窗口:

protected void ddpaygrade_SelectedIndexChanged(object sender, EventArgs e)
{
    ModalPopupExtender3.Show();
}

不要忘记在你的标记中连接事件:

<asp:DropDownList ID="ddpaygrade" runat="server" AutoPostBack="true" 
    class="m-wrap large" AppendDataBoundItems="false" 
    OnSelectedIndexChanged="ddpaygrade_SelectedIndexChanged" >    
</asp:DropDownList>
