refresh probelm in ASP.NET?

Hi,I am creating web application. This application contains LIVE streaming
data(i.e second by second). For that i want to refresh page, so i add html code


<metahttp-equiv="Refresh"content="2"/>. This will
refresh after 2 seconds.

If i refresh then only i will receive data. 

This data displays in GRIDVIEW. I wrote all the code in Page_Load.

I wrote a condition like comparing two columns, when this condition satisfied
display message in LABEL. When time of refresh this message also disappear. 

I want to display a message for 10 seconds.

How to display that. 

help me anyone.....

This is helpfull to me. Thanks

In my design page update panel control not moving, How to move.

And i am unable arrange all the controls properly, becus its not moving.

Give me the way to do this. . .

I'm sorry, I don't think I understand what you mean by moving the UpdatePanel.
It's drag and drop in design mode. Have you tried editing the layout in the
source code? This may be a good alternative if you can't arrange the layout how
you'd like it in design mode.

I think the best solution for this would be to use the asp.net Ajax Timer
control.

Once your condition is met, you could programmitically increase the timer
interval to 10 seconds (Timer1.Interval = 10) when you display your message in
the label.

try this in the code side.. 

// To Refresh the page automatically after every (10 seconds).

   Response.AppendHeader("Refresh", "10;URL=WebForm2.aspx");
 // ten seconds..
