Need Help on RadProgressArea

[Han]

Hi,

Can you show me how to use RadProgressArea while loading data from a sql server?  Here is my scenario:

I have a RadButton.  when a user click on this button, I have a function call RetrieveData() and this function will connect to a sql database and query about 100,000 records and performing a lot of data manipulation so it will take awhile to produce desire data.

while processing the data, I would like to display like a progress bar so user can see what's going on and wait.  I found the demo here:
http://demos.telerik.com/aspnet-ajax/upload/examples/customprogress/defaultcs.aspx and really like it, but I don't know how to apply it to my scenario.  From the example, it sets the total process = 100, but in my case, my query run can take up to 3 minutes.  Please provide code as possible.  Here is my code behind page:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            //Do not display SelectedFilesCount progress indicator.
            RadProgressArea1.ProgressIndicators &= ~ProgressIndicators.SelectedFilesCount;
        }

        RadProgressArea1.Localization.Uploaded = "Total Progress";
        RadProgressArea1.Localization.UploadedFiles = "Progress";
        RadProgressArea1.Localization.CurrentFileName = "Please wait while updating database... ";
    }

protected void RetrieveData()
{
        //using LINQ to SQL to select data
}

private void UpdateProgressContext()
    {

        RadProgressContext progress = RadProgressContext.Current;

        const int total = 100;

        progress.Speed = "N/A";
        for (int i = 0; i < total; i++)
        {
            progress.PrimaryTotal = 1;
            progress.PrimaryValue = 1;
            progress.PrimaryPercent = 100;

            progress.SecondaryTotal = total;
            progress.SecondaryValue = i;
            progress.SecondaryPercent = i;

            progress.CurrentOperationText = "Step " + i.ToString();

            if (!Response.IsClientConnected)
            {
                //Cancel button was clicked or the browser was closed, so stop processing
                break;
            }

            progress.TimeEstimated = (total - i) * 100;

            //Stall the current thread for 0.1 seconds
            System.Threading.Thread.Sleep(50);
        }
    }

protected void RadButton1_Click(object sender, EventArgs e)
   {
       UpdateProgressContext(); //I assume this is how it call
       RetrieveData();
   }

Please help, thanks in advance!
