Hi Han,
I don't think you understood me. I'll try to be more specific.
The progress that you see on the screen in the ProgressArea, is only updated inside the for loop. There you set explicitly the number of "transferred items", the number of "remaining items", the remaining time etc. Any actions or methods outside the loop won't register in the ProgressArea. To update it, you have to set all the properties
manually at equal (if possible) intervals.
I'll try to explain it with an example. Say you have a method that goes through a list of integer numbers and adds their sum. Here's how you can monitor the process of this method:
aspx.
cs.
private static Random rand = new Random();
List<int> numbers = new List<int>();
protected void Page_Load(object sender, System.EventArgs e)
{
for (int i = 0; i < 400; i++)
{
numbers.Add(rand.Next(0, 400));
}
RadProgressArea1.Localization.Uploaded = "Total Progress";
RadProgressArea1.Localization.UploadedFiles = "Progress";
RadProgressArea1.Localization.CurrentFileName = "Custom progress in action: ";
}
protected void buttonSubmit_Click(object sender, System.EventArgs e)
{
Label2.Text = SumNumbers(numbers).ToString();
}
private int SumNumbers(List<int> numbers)
{
int total = numbers.Count;
int sum = 0;
RadProgressContext progress = RadProgressContext.Current;
progress.Speed = "N/A";
for (int i = 0; i < total; i++)
{
sum += numbers[i];
progress.PrimaryTotal = 1;
progress.PrimaryValue = 1;
progress.PrimaryPercent = 100;
progress.SecondaryTotal = total;
progress.SecondaryValue = i;
progress.SecondaryPercent = (i*100)/total;
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(30);
}
return sum;
}
Please note that the updating of the process happens inside the monitored method itself.
