    Dear all,

    I am using a RadUpload to display a lengthy operation that collecting data, it is performing well.
    I need to execute another lengthy process after that using the same upload control, but it doesn't ... it just postback with nothing displayed.
    Here is my scenario:
    RadProgressContext context = RadProgressContext.Current;  
    context.PrimaryTotal = mm.Count.ToString();  
    context.SecondaryTotal = mm.Count.ToString();  
     
    for (int i = 0; i < mm.Count; i++)  
    {  
        context.PrimaryValue = i.ToString();context.PrimaryPercent = i.ToString();  
        context.SecondaryValue = i.ToString();context.SecondaryPercent = i.ToString();  
          
        context.CurrentOperationText = "Generating : " + mm[i].Name;  
        if (!Response.IsClientConnected) break;  
        // My processing goes here ...  
    }  
     
    I need to do another loop to perform additional processing using the same concept as the above but it doesn't

    How can I achieve that ..

    Best regards,
    Waleed

    Hi Waleed Seada,

    I have prepared sample project that demonstrates how to monitor two subsequent progresses. You can find the sample as an attachment.

    Hello Genady,

    Appreciate your reply indeed.

    I review the aspx script and I found few differences; you have a hidden input that is not used and a empty method for the onload of the progressArea also the script manager has the EnablePageMethods="true", EnablePartialRendering="true", these are the only differences in the aspx script I can see, please confirm which is affecting the scenario.

    I try to do this:
    RadProgressContext context = RadProgressContext.Current;     
    context.PrimaryTotal = mm.Count.ToString();     
    context.SecondaryTotal = mm.Count.ToString();     
        
    for (int i = 0; i < mm.Count; i++)     
    {     
        context.PrimaryValue = i.ToString();context.PrimaryPercent = i.ToString();     
        context.SecondaryValue = i.ToString();context.SecondaryPercent = i.ToString();     
             
        context.CurrentOperationText = "Generating : " + mm[i].Name;     
        if (!Response.IsClientConnected) break;     
        // My processing goes here ...     
    }     
    context.PrimaryTotal = array1.length + array2.length + array3.length ;  
    context.SecondaryTotal = array1.Length.ToString();  
    for (int i = 0; i < array1.Length; i++)  
    {  
        context.PrimaryValue = i;context.PrimaryPercent = i;  
        context.SecondaryValue = i;context.SecondaryPercent = i;  
     
        context.CurrentOperationText = "Saving array1 : " + i;  
        if (!Response.IsClientConnected) break;  
        // additional processing  
    } 
    I set the PrimaryTotal equal to be the total length of all business objects (I have 25 of them) I am using (aray1, array2, ....) and then I construct a for loops for each object (array) in which I increment the PrimaryValue and the SecondaryValue while processing.

    It doesn't show unless I put I breakpoint then I can see it all okay, without the breakpoint it just flash and nothing shows on.

    I forgot to add that your progress doesn't reset between loops, while it should to reflect the actual process.

    Hello Waleed Seada,

    The reason why you don't see the area is that the progress that you monitor is executed as fast as a second or even less by the CPU. In order to see the area appearing you will need to slow down the custom progress. You can do this using the following call:

    System.Threading.Thread.Sleep(100);

    Put that line in the body of your for cycles and the area will appear. As for the context not resetting, I have noticed that only for the time elapsed value. Unfortunately, due to a bug in the current implementation of the area it is not possible to reset that value. I am currently searching for a workaround.

    All the best,

    Hello Genady Sergeev,

    Appreciate your time you r spending to resolve the issue.

    I notice that the process is too fast and I manage to slow it down a little bit to be noticeable to the user.

    If you manage to find a workaround for resetting the context will be great !!

    Best regards
    Waleed
