Use of ASP. NET User Controls

Create a user control as follows:

The front-end Page code is as follows:

View Code

 1 <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Content.ascx.cs" Inherits="WLaw.Vip.Help.Content" %>
 2 
 3 
 4 <div >
 5             <p    
 6 
 7 　　　　　　<span>
 8                  　　<asp:Label ID="lblTitle" runat="server" Text=""> </asp:Label>
 9 
10 　　　　　　</span>
11             </p>
12             <asp:Label ID="lblFullContent" runat="server" Text=""> </asp:Label>
13  </div>

 

Server code:

       public HelpInfo hif;
public HelpContentInfo HelpContent;

protected void Page_Load(object sender, EventArgs e)
        {
if (!IsPostBack)
            {
                PageInit();
            }

        } 
private void PageInit()
        {
if (hif == null)
            {
return;
            }
            lblTitle.Text = hif.Title;
            lblFullContent.Text = HelpContent.FullContent;
        }

 

Use User Controls

Register a user control on the page

<%@ Register  Src="~/Help/Content.ascx" TagName="UserContorl" TagPrefix="USContent" %>

Call the user control:

 <UC:UserContorl runat="server" ID="LeftProServer1" />

Server code:

View Code

 1   protected void Page_Load(object sender, EventArgs e)
 2         {
 3             if (!IsPostBack)
 4             {
 5                 int HelpId = Convert.ToInt32(Request["hId"]);
 6                 HelpInfo hp = HelpBiz.Get(HelpId);
 7                 HelpContentInfo HelpContent = HelpContentBiz.Get(HelpId);
 8                 USContent1.hif = hp;
 9                 USContent1.HelpContent = HelpContent;
10 
11                 _title.InnerText = hp.Title;
12             }
13         }
