Show Yahoo weather using ASP.Net
Step 1)Open a AJAX enable ASP.NET page in Visual Studio.
Step 2) Add following code in your ASP.Net page.
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Yahoo_weather.aspx.cs"
Inherits="Yahoo_weather"
%>
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"

</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1"
runat="server"
/>
<asp:UpdatePanel ID="UpdatePanel1"
runat="server">
<ContentTemplate>
<asp:Timer ID="Timer" runat="server" OnTick="Tick" Interval="1000" />
<asp:Panel ID="WeatherUpdatePanel"
runat="server"
/>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Step 3) Add below code
in code behind of your ASP.Net page
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;
using System.Collections.Generic;
using System.Data;
using System.Xml;
public partial class Yahoo_weather :
System.Web.UI.Page
{
protected void Tick(object sender, EventArgs
e)
{
string RSS = "http://weather.yahooapis.com/forecastrss?w=2502265";
//Change w value to get your location ...
XmlDocument xDoc = new
XmlDocument();
xDoc.Load(RSS);
XmlNodeList ItemList = xDoc.GetElementsByTagName("item");
string Title = ItemList[0].SelectSingleNode("title").InnerText;
string Description = ItemList[0].SelectSingleNode("description").InnerText;
WeatherUpdatePanel.Controls.Add(new LiteralControl("<p>"
+ Title + "</p>"));
WeatherUpdatePanel.Controls.Add(new LiteralControl("<p>"
+ Description + "</p>"));
}
}
I tried this, but error returned: "WeatherUpdatePanel is not found in the current context". How would you fix that?
ReplyDeleteThank you
this error occurred because you didn't place a panel control with id 'WeatherUpdatePanel'.
