Question

I am developing one chart application on .net framework by using Silverlight and Visifire, Its a silverlight application and I am running it on localhost.
I have connected through SQL server database to my application and it is running fine, The main thing that i am looking for is that, when i change data inside the database, It should dynamically change my application’s chart values.

What I tried is, I set the page refreshing parameter in my web page and its updating the values also, but whole application is re-appearing.

So, Is there any way to change the chart value parallely as I change my values in database.

Looking forward for response,

Thanks.

You can use “DispatcherTimer” in Silverlight application and call UpdateChart() on each tick event of the timer. Checkout the sample code below.

public Page()
{
    System.Windows.Threading.DispatcherTimer timer = new DispatcherTimer();
    timer.Interval = new TimeSpan(0, 0, 10); // 10 sec
    timer.Tick += new EventHandler(timer_Tick);
    timer.Start();
}

void timer_Tick(object sender, EventArgs e)
{
    UpdateChart();
}

Hope this helps!
