为什么模态弹出扩展器没有显示 [英] Why modal popup extender is not showing

问题描述

代码运行时没有错误，但模态弹出窗口不可见。如何使它起作用？

 <   asp：UpdatePanel     ID   =  gt    runat   =  server   < span class =code-attribute> UpdateMode   = 条件 >  
 <  触发器 >  
 <   asp：AsyncPostBackTrigger     ControlID   =  BtnEnquirySend    /  >  
 <   / Triggers  >  
 <   ContentTemplate  >  
 <   asp：按钮    ID   =  BtnEnquirySend    runat   =  server     文字  = 发送    style   =  left：910px;顶：845px; position：absolute;    OnClick   =   BtnSend_Click      /  >  
 <  < span class =code-leadattribute> asp：Panel     ID   =  Panel11    runat   =  server    style   =  height：300px;宽度：200像素;保证金左：170像素; margin-top：400px >  <   / asp：面板 >  
 <   asp：ModalPopupExtender     ID   =  MPE    runat   =  server  
   
      < span class =code-attribute>     TargetControlID   =  BtnEnquirySend  
   
           PopupControlID   =  Panel11  
   
           BackgroundCssClass   =  modalBackground  
   
           DropShadow   =  true  
   
           OkControlID   =  OkButton  
   
           OnOkScript   =  onOk（）   
   
           CancelControlID   =  CancelButton  
   
           PopupDragHandleControlID   =  Panel11   >  
 <   / asp：ModalPopupExtender  >  
 <   / ContentTemplate  >  
 <   / asp：UpdatePanel  >  

  protected   void  BtnSend_Click（ object  sender，EventArgs e）
 {
 MPE 。节目（）; 
} 

解决方案

试试这个：

< asp：UpdatePanel ID =   gt runat =   server UpdateMode =  条件> 
<触发器> 
< asp：AsyncPostBackTrigger ControlID =   BtnEnquirySend /> 
< /触发器> 
< ContentTemplate> 
< asp：按钮ID =   BtnEnquirySend runat =   server Text =  发送 style =   left：910px; top：845px; position：absolute; OnClick =   BtnSend_Click /> 
< asp：Panel ID =   Panel11 runat =   server style =  高度：300px;宽度：200px;左边距：170px;边距顶部：400px> 
< asp：标签ID =   Label3 runat =   server Text =  检查>< / ASP：标签> 
  //  包含的标签用于检查 
< / asp：Panel> 
< asp：ModalPopupExtender ID =   MPE runat =   server 
 TargetControlID =   BtnEnquirySend 
 PopupControlID =   Panel11 
 BackgroundCssClass =   modalBackground 
 DropShadow =   true> 
< / asp：ModalPopupExtender> 
< / ContentTemplate> 
< / asp：UpdatePanel> 

面板没有值。这就是为什么它看起来没有显示。

The code runs without error but modal popup is not visible. How to make it function?

<asp:UpdatePanel ID="gt" runat="server" UpdateMode="Conditional">
    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="BtnEnquirySend" />
    </Triggers>
    <ContentTemplate>
    <asp:Button ID="BtnEnquirySend" runat="server"  Text="Send" style=" left:910px; top:845px; position:absolute;" OnClick="BtnSend_Click"  />
    <asp:Panel ID="Panel11" runat="server" style=" height:300px; width:200px; margin-left:170px; margin-top:400px"></asp:Panel>
    <asp:ModalPopupExtender ID="MPE" runat="server"

    TargetControlID="BtnEnquirySend"

    PopupControlID="Panel11"

    BackgroundCssClass="modalBackground"

    DropShadow="true"

    OkControlID="OkButton"

    OnOkScript="onOk()"

    CancelControlID="CancelButton"

    PopupDragHandleControlID="Panel11" >
    </asp:ModalPopupExtender>
    </ContentTemplate>
    </asp:UpdatePanel>

protected void BtnSend_Click(object sender, EventArgs e)
    {
        MPE.Show();
    }

解决方案

Try this:

   <asp:UpdatePanel ID="gt" runat="server" UpdateMode="Conditional">
    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="BtnEnquirySend" />
    </Triggers>
    <ContentTemplate>
    <asp:Button ID="BtnEnquirySend" runat="server"  Text="Send" style=" left:910px; top:845px; position:absolute;" OnClick="BtnSend_Click"  />
    <asp:Panel ID="Panel11" runat="server" style=" height:300px; width:200px; margin-left:170px; margin-top:400px">
        <asp:Label ID="Label3" runat="server" Text="Check"></asp:Label>
//label included to check
    </asp:Panel>      
    <asp:ModalPopupExtender ID="MPE" runat="server"
    TargetControlID="BtnEnquirySend"
    PopupControlID="Panel11"
    BackgroundCssClass="modalBackground"
    DropShadow="true">
    </asp:ModalPopupExtender>
    </ContentTemplate>
    </asp:UpdatePanel>

The panel has no values.That's why it looks like not showing.
