将setter调用移至onload事件

受保护的覆盖无效void OnLoad(EventArgs e) { base.OnLoad(e); 字符串par1 =(字符串)ViewData ["myvar"]; ReportViewer1.Report =新的MyProj.Web.Reports.Rep1(par1); }

My way to ASP.NET MVC was not across ASP.NET Web Forms, so it's hard for me to understand how better to pass value from ASP.NET MVC controller to ASP.NET webforms script which is inside MVC View.

For example, controller action:

 public ViewResult Print(string id)
    {
       ...
       string myvar = "realvalue"; 
       return View();
    }   

My view:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
...
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <script runat="server">
      ...  
     string par1 = "stubvalue";

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        ReportViewer1.Report = new MyProj.Web.Reports.Rep1(par1);
    }
    </script>
<telerik:ReportViewer runat="server" ID="ReportViewer1" />
</asp:Content>

How to assign a value of myvar from a controller action to par1 variable in the View instead "stubvalue"?

Move the setter call to onload event

protected override void OnLoad(EventArgs e) { base.OnLoad(e); string par1 = (string) ViewData["myvar"]; ReportViewer1.Report = new MyProj.Web.Reports.Rep1(par1); }
