hi..
I am working on stocks manageent.I want updated price of shares.I am using rss feed.I have use grid view to make rss.But problem is i am not able to decode thhis xml rss.
Plz help how i cause rss to show updated stocks price.
here is code that i try-
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
XmlTextReader reader = new XmlTextReader("http://blogs.ibibo.com/sharetipsfree/feed/rss");
DataSet dataset = new DataSet();
dataset.ReadXml(reader);
GridView1.DataSource = dataset.Tables[2];
GridView1.DataBind();
}
|

The RSS that you have mentioned is about some definations.
However the above code is to read the XML and display same on the page.
But if you want your code to display the updated pricing, then the rss xml must be updated after some interval of time.
If you can do the same, only then report will display the updated values

Hi
The above link is not providing any rss.
If the same is rss then the link should be giving some xml file.
The link is accepting some query string arguments, reading and displaying the same on scree.
You cannot do any thing with this.
Search for RSS for the same

CommandArgument='<%# Bind("ID")>' is it possible to send id&name within the same command argument

Why dont you use the Client itself to do the redirection instead of coming back to the server and doing Response.Redirect.
In short you need to write a Javascript function which will execute on click of OK button.
function RedirectAfterMessage()
{
var message = "do you wanna redirect?";
if(confirm(message))
window.location = "www.google.com";
}
