Posted on 2013-01-08
i have silverlight page, it has a datagrid. I have created a WCF service which generates data for that datagrid. In my silverlight page, i call that service as shown below
MyService.MyServiceClient mysvcclient1;
mysvcclient1= new MyService.MyServiceClient(
mysvcclient1.GetDataGridDa
mysvcclient1.GetDataGridDa
mysvcclient1.CloseAsync();
}
now i want to refresh that data every 30 seconds... what is the best way to do that?
thanks....

now i want to refresh that data every 30 seconds... what is the best way to do that?

Have a Timer in silverlight and refresh your datagrid.
1. When making call , stop the timer.
2. When the async call comes back , start the timer.
