ASP.NET WebForms模态弹出窗口

Question

我想知道在ASP.NET WebForms应用程序中显示模式弹出窗口的最佳方法是什么.我需要显示带有2个按钮的模态窗口(确定/取消)并在我的代码中按下按钮.我应该用它来实现它 - 来自AjaxControlToolkit,bootstrap模式弹出窗口或jQuery UI的ModalPopupExtender？我是ASP.NET WebForms的新手,所以源代码或教程的示例会派上用场.谢谢!

嘿,请使用modalpopupextender检查此代码:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

然后从按钮打开PopUp的On Click事件后面的Code:

     <asp:Button ID="btnOpenPopUp" runat="server" text="Open PopUp" />
     <asp:Label ID="lblHidden" runat="server" Text=""></asp:Label>
        <ajaxToolkit:ModalPopupExtender ID="mpePopUp" runat="server" TargetControlID="lblHidden" PopupControlID="divPopUp" BackgroundCssClass="modalBackground"></ajaxToolkit:ModalPopupExtender>

<div id="divPopUp" class="pnlBackGround">
     <div id="Header" class="header" >MyHeader</div>
     <div id="main" class="main">Main PopUp </div>
     <div id="buttons">
          <div id="DivbtnOK" class="buttonOK"><asp:Button id="btnOk" runat="server" text="Ok" /></div>
          <div id="Divbtncancel" class="buttonOK"><asp:Button id="btnCancel" runat="server" text="Cancel" /></div>
     </div>
</div>

然后点击Ok Button:

protected void btnOpenPopUp_Click(object sender, ImageClickEventArgs e)
{
    mpePopUp.Show();
}

在取消单击按钮:

protected void btnOk_Click(object sender, ImageClickEventArgs e) {
    //Do Work

    mpePopUp.Hide(); }

提示:如果您没有ajax工具包,可以使用Nuget进行安装.
