ModalPopupExtender从服务器端代码在c＃ [英] ModalPopupExtender from Server Side Code in c#

问题描述

将ModalPopupExtender添加到窗体很容易，你可以放下它，告诉它两个必需的控件参数

  PopupControlID =MyModalPanel
 TargetControlID =ButtonToLoadIt
  

它只是工作正常，但是由客户端点击目标控件触发。

想做一些服务器端代码吗？如何做？

解决方案

示例代码如下所示：

HTML CODE：

 <！ -  Hidden Field  - > 
< asp：HiddenField ID =hidForModelrunat =server/> 
 
< asp：ModalPopupExtender 
 ID =WarningModal
 TargetControlID =hidForModel
 runat =server
 CancelControlID =btnWarning
 DropShadow =true
 PopupControlID =pnlIssues> 
< / asp：ModalPopupExtender> 
 
<！ -  Panel  - > 
< asp：Panel ID =pnlIssuesrunat =server
 BorderColor =BlackBorderStyle =Outset
 BorderWidth =2BackColor =Wheat 400pxHeight =106px> 
< center> 
< h2 class =style2> 
信息< / h2> 
< p> 
 
< h3> < asp：Label ID =lblWarning
 runat =server> < / asp：Label>< / h3> 
< / p> 
 
<！ - 在面板中关闭弹出式窗口的标签 - > 
< asp：ImageButton ID =btnWarningrunat =server
 ImageUrl =〜/ images / buttons / update.png/> 
< / center> 
 
< / asp：Panel> 
  

C＃代码

 code> WarningModal.Show（）; 
 lblWarning.Text =这是一个弹出警告;

I had a nightmare getting this going.

Adding the ModalPopupExtender to a form is easy, you drop it on and tell it the two required controls parameters

PopupControlID="MyModalPanel"
TargetControlID="ButtonToLoadIt"

And it just works fine, but is triggered by a client side click of the Target Control.

If you want to do some server side code behind??? how to do it ?

解决方案

The example code is shown below:

HTML CODE:

<!-- Hidden Field -->
<asp:HiddenField ID="hidForModel" runat="server" />

<asp:ModalPopupExtender
ID="WarningModal"
TargetControlID="hidForModel"
runat="server"
CancelControlID="btnWarning"
DropShadow="true"
PopupControlID="pnlIssues" >
</asp:ModalPopupExtender>

<!-- Panel -->
<asp:Panel ID="pnlIssues" runat="server"  
BorderColor="Black" BorderStyle="Outset"  
BorderWidth="2" BackColor="Wheat" Width="400px"  Height="106px">
   <center>
       <h2 class="style2">
           Information</h2>
       <p>

         <h3> <asp:Label ID="lblWarning" 
runat="server"> </asp:Label></h3>
       </p>

 <!-- Label in the Panel to turn off the popup -->
 <asp:ImageButton ID="btnWarning" runat="server"
                ImageUrl="~/images/buttons/update.png" />
</center>

</asp:Panel>

C# Code

WarningModal.Show();
lblWarning.Text = "This is a popup warning";
