chapter10
Hi,
Sorry for disturbing again. Now some problem with Chapter 10, Using the New control
TIO(page 375).
Ther first point suggested that- "Open Visual Developer and select Open website
.From the Chapter10 folder (C:\BegASPNET2\Chapters\Begin\Chapter10),Select WroxUnitedNewsControl and
click OK." Now the problem is that in Chapter10 there is no folder named as WroxUnitedNewsControl.
Chapter 10 folder contains NewsUserControl,ObjectDataSource,SimpleUserControl ,TestCodeBehind and WroxUnited folders only.
So I have tried that TIO in NewsUserControl folder.
But when I run the NewsDisplay.aspx , it is not showing anything rather than a blank page.
The codes are as follows:
NewsUserControl.ascx:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="NewsUserControl.ascx.cs" Inherits="NewsUserControl" %>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:WroxUnited %>" ></asp:SqlDataSource>
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<div class="newsItem">
<span class="newsDate"><%#Eval("DateToShow","{0:dd MM yyyy}") %></span>
<span class="newsTitle"><%#Eval("Title") %></span>
</div>
<span class="newsContent"><%#Eval("Description") %></span>
</ItemTemplate>
</asp:Repeater>
NewsUserControl.ascx.cs:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class NewsUserControl : System.Web.UI.UserControl
{
private int _itemsToShow = 5;
public int ItemsToShow
{
get
{
return _itemsToShow;
}
set
{
_itemsToShow = value;
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Repeater1_PreRender(object sender, EventArgs e)
{
string sel = string.Format("SELECT Top {0} * FROM [News] WHERE DateToShow <= '{1}' ORDER BY DateToShow DESC", _itemsToShow, DateTime.Now.ToString("yyyy/MM/dd"));
//Make sure above is all on one line.
SqlDataSource1.SelectCommand = sel;
}
}
NewsDisplay.aspx:
