ASP.NET Code
protected void Page_Load(object sender, EventArgs e)
{
raporcek();
}
protected void drplist_SelectedIndexChanged(object sender, EventArgs e)
{
raporcek();
}
private void raporcek()
{
try
{
string deger = drplist.SelectedValue.ToString();
XmlTextReader txt = new XmlTextReader("http://weather.yahooapis.com/forecastrss?w=" + deger + "&u=c");
while (txt.Read())
{
if (txt.Name == "yweather:condition")
{
string a = txt.GetAttribute("temp");
ltrderece.Text = a;
}
}
string RSS = "http://weather.yahooapis.com/forecastrss?w=" + deger + "&u=c";
//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;
string[] resim = Description.Split('"');
imgsrc.Src = resim[1].ToString();
}
catch
{
}
}
So our page not postback,only "update panel" division change...
