Upload (Obsolete)

Hi,
I have an application that uses the RADprogress Manager. On my dev machine, it works fine, during the file upload the progress bar appears and updates. I move the application to my production server and the file uploads but no progress area. In reviewing the forums and other support, I've done/checked the following
- Ensure the two registrations are in web.config (the prod srv is the same - I just change the connection string after I load it)
- No Ajax
- tried setting trust level="Full"
- updated to latest assemblies

I did not try registering the assembly in the GAC, as I run several other website on the server and was uncertain of the effect on them.

The production server is windows 2003 with IE 6. It is a dedicated server, not shared. The browser is IE 8. My dev environment is Windows XP, Visual Studio 2008.

The only two differences I can see beyond the OS difference is that on the produciton server, the website runs as a Virtual Directory under a second website that does not have the appropriate registrations in the web.config. I didn't purse that further since upload works. I assume that wouldn't work if it wasn't seeing the registrations
The other difference is the production server is running dotDefender as an application firewall. That firewall has not caused any other code issues..

Thanks for you help,
Bob

Hi Robert O'Dell,

The registrations in the web.config have nothing to do with the actual file upload. They are only for the sake of the progress area. I have the following suggestions:

1) Can you try to disable the firewall and check whether the area will appear when uploading, say 20 mb file?
2) Check whether you have any HttpModules that are catching on the HttpContext.
3) Just for the purpose of testing, can you try to add the needed handler/module to the parent site web.config?
4) I have prepared very simple upload application that works on all common cases. Can you try to attach it in the same way as your real application and observe whether there is a progress bar visible. If there is no progress, this shall mean that the problem lays somewhere in the parent site.

Hi Genady,

I've got the same challenge.   Thanks for the demo. I did as you suggested and installed it on a fresh virtual directory, and also ensure there was no web.config at the root of the web.

Two things:
1) I've installed Telerik into the GAC, and had to add the full spec to all the references in web.config
<add path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"   validate="false" />

instead of:

<add path="Telerik.RadUploadProgressHandler.ashx" verb="*" type="Telerik.Web.UI.RadUploadProgressHandler, Telerik.Web.UI"   validate="false" />

..do I get around this via adding Telerik to machine.config?

and

2) file goes up, but still no progress manager visible.

Clues:

I know that RadUploadProgressHandler is working, as I use firefox/firebug, and I can see it returning this every few seconds:

var rawProgressData = {InProgress:true,ProgressCounters:true,CurrentOperationText:'testfile.zip',PrimaryTotal:'1.31MB',PrimaryValue:'455.39kB',PrimaryPercent:'34',SecondaryValue:'0',Speed:'41.02kB/s',TimeElapsed:'10921',TimeEstimated:'21761',OperationComplete:'false',RadUpload:{RequestSize:1372628,Bytes:466324,FilesCount:0,CurrentFileName:'testfile.zip',RequestLength:1372628}};

But no progress manager displayed? Seems like a client side visibility thing?

Hope you can help - love your products, and your friendly patient support. :-)

[edit] p.s. Can't find a PM button, or I would send you the link to test... :-)

Genady,
Thanks for the input. Here's what I tried
The registrations in the web.config have nothing to do with the actual file upload. They are only for the sake of the progress area. I have the following suggestions:

1) Can you try to disable the firewall and check whether the area will appear when uploading, say 20 mb file?
That I can't turn off. We are using a CISCO hardware firewall and there is really no practical way of taking that out of the loop. I did turn off dotDefender which was the web application firewall (after taking a Zantac) and tried it - no luck.

2) Check whether you have any HttpModules that are catching on the HttpContext.
Not sure what you suggesting here, can you enlighten me a little

3) Just for the purpose of testing, can you try to add the needed handler/module to the parent site web.config?
Tried that to no avail. I also went to another site and modified the base web.config and added the web page directly. Same result
As a third test, I went to a second server added the test you sent and had the exact same result

4) I have prepared very simple upload application that works on all common cases. Can you try to attach it in the same way as your real application and observe whether there is a progress bar visible. If there is no progress, this shall mean that the problem lays somewhere in the parent site.
Tried this at the same level, and modified a web site so it was not a virtual directory, still no luck.

Some observations from this round.
Uploading a 30MB file, the progress manager actually appears -- but when the upload is done!! The page actually never finishes loading, the green bar shows all the ways across, but the rotating circles - rotates and rotates. But as I said the files actually uploaded completely.

I tried uploading several very small files. In that case, the progress manager never appeared (but that might be correct in this case) and the page did fully complete providing the completion message (this was my program not your test). Other suggestions?
Thanks,
Bob

Hi Robert O'Dell,

I am a little bit confused, what do you mean by:

"The page actually never finishes loading, the green bar shows all the ways across, but the rotating circles - rotates and rotates"

Do you use any templates for the progress area? By default there are no circles, your description looks like the description of an ajax indicator. Is this what you see? In additon, the fact that the area appears after the file upload means that there is some process running in the background that keeps the progress context. Are you sure that you don't have any methods in the code-behind that interact with the progress area context? Something like the following:

RadProgressContext context = RadProgressContext.Current;

context.SecondaryTotal = 200;

for (int i = 0; i < 200; i++)

{

//Progress bar

int percentIncrement = Convert.ToInt32(i * 100 / rgCount);

context.SecondaryValue = (i + 1).ToString();

context.SecondaryPercent = percentIncrement.ToString();

context.CurrentOperationText = (i + 1).ToString();

}

All the best,

Genady,
Sorry, What I meant by the rotating circles was the small rotating circle that appears in the place of the IE log on the browser tab for the page. It's nothing in my code.

Now for your questions "is it something in my code behind" I'm pretty sure not. I've included the pertinent code below. The only other code is some logging and configuration which are not active during the load.

    
             #region Load and Save Data

                    {  
        
                        lblError.Text += " fcnt=" + RadUpload1.InvalidFiles.Count.ToString();  
        
                        foreach (UploadedFile invalidFile in RadUpload1.UploadedFiles)  
        
                        {

Hi Robert O'Dell,

I am starting to think that this is indeed client side visibility problem. Everything else looks normal and since the ProgressHandler is returning correct information there should be progress area visible. Which browser do you use? Here is an easy way to check whether this is a client side problem:

protected void Page_Load(object sender, EventArgs e)

{

UpdateProgressArea();

}

private void UpdateProgressArea()

{

//Set the RadProgressContext values which will be serialized on the client.

//The values set here are just as an example

RadProgressContext progress = RadProgressContext.Current;

progress["PrimaryTotal"] = string.Format("{0} bytes", 1000);

progress["PrimaryValue"] = string.Format("{0} bytes", 600);

progress["PrimaryPercent"] = "60";

progress["SecondaryPercent"] = "30";

progress["CurrentOperationText"] = "MyTestFileMyTestFileMyTestFileMyTe stFileMyTestFile MyTestFileMyTestFile.txt";

progress["SecondaryTotal"] = string.Format("{0} file(s)", 1);

progress["SecondaryValue"] = string.Format("{0} file(s)", 0);

progress["Speed"] = "30KB/s";

progress["TimeEstimated"] = "0:0:20s";

progress["TimeElapsed"] = "0:0:3s";

StringWriter writer = new StringWriter();

progress.Serialize(writer);

string script = string.Format(@"function displayProgressAreas() {{ {1};$find('{0}').update(rawProgressData);}}",

RadProgressArea1.ClientID, writer.GetStringBuilder().ToString());

string script1 = "Sys.Application.add_load(function(){ displayProgressAreas();});";

string script2 = String.Concat("<script type='text/javascript'> ", script, script1, " </script>");

ClientScript.RegisterStartupScript(this.GetType(), "DisplayProgressAreas", script2, false);

}

Copy and paste this code to your page. Then change RadProgressArea1 to the ID of your RadProgressArea. Is there progress area present on initial load of the page?

Hi Robert O'Dell,

This is really confusing, since the handler sends the upload data to the client there should be progress area visible. Have you tried to inspect your page with FireBug or IEToolBar and manually set display="block" to the RadProgressArea div? I have the following suggestions:

1) Add a button to your aspx page and the following code for its event handler:

protected void btnStart_Click(object sender, EventArgs e)

{

int rgCount = 200;

RadProgressContext context = RadProgressContext.Current;

context.SecondaryTotal = 200;

for (int i = 0; i < 200; i++)

{

//Progress bar

int percentIncrement = Convert.ToInt32(i * 100 / rgCount);

context.SecondaryValue = (i + 1).ToString();

context.SecondaryPercent = percentIncrement.ToString();

context.CurrentOperationText = (i + 1).ToString();

if (!Response.IsClientConnected)

{

//Cancel button was clicked or the browser was closed, so stop processing

break;

}

// simulate a long time performing the current step

System.Threading.Thread.Sleep(1000);

}

Is there progress area visible when you press the button?

2) Hook on the client side ProgressUpdating event of the RadProgressManger. Thena add the following as a handler:

<script type="text/javascript">

function ProgressUpdating(sender, args) {

alert(args.ProgressData.PrimaryPercent);

}

</script>

If there is correct result as a PrimaryPercent, the problem should sort of client side visibility thing. Do you have Live URL where we can observe the problem?

I'm experiencing this same issue where the progress area never turns visible and I'm able to see the requests piling up in Firebug or any other monitoring tool with this in the reponse "var rawProgressData = {InProgress:false,ProgressCounters:false};". Even when manually changing the display to "block" to get the progress area to show up it never displays any valid progress data (see attachment).

Genady,
The first test you asked me to try was adding the btnStart_Click and a button to call it. I Tried that and it came up fine on the production server. It would go from 1 to 200 perfectly. (I did change it 50 to shorten after the first test - and that continued to work fine).

The second test was attaching to the OnClientProgressUpdating event. That worked fine on my dev machine, On the production server it did not, I did not get any alert there. In all cases the test file I'm uploading was loaded correctly. I've been using a test file of approximately 13MB.

One interesting note. On my postback (the update button), I put a call to you btnStart_Click as the first statement. What happened there is the file uploaded (with no progress manager). After which the progress manager appeared from the btnStart_Click. When you go to the test page below, that link has been removed.

To reach the test page. The URL is:

Hi Robert O'Dell,

Can you please open a support ticket and send your web.config to us? After a lot of researching we are somewhat confused on what might be the cause of the area not appearing. Do you have global.asax file in your app? We have managed to reproduce a similar problem but when there is an HttpModule attached to an event of the HttpApplication object that is fired earlier than the event the area hooks on. The area's module hooks on PreRequestHandlerExecute. As far as I can see from the live URL you use IIS6.0. Do you have any ISAPI filters applied?

Good evening,

I am experiencing the same issues described in this post - has there been any resolution to this?

I implement the example as per the demo code (http://demos.telerik.com/aspnet-ajax/upload/examples/customprogress/defaultcs.aspx)
and implement the http handlers and httpRuntime sections in the web.config.

I have tested this on three seperate servers now (internal and discountasp) and they all come up with the same symptoms - the page hangs until the file has been posted fully without showing any progress / progress area - then it clicks in and the progress is shown.

FYI I'm developing my solution in .net 2.0

Hello drickey,

No, since we were not able to reproduce the problem on out side. Do you have sample project that reproduces the problem and can be test locally? If so, please open a support ticket and send it to use so that we can investigate on what is going wrong.

Despite that, there might be numerous of reasons for the area not appearing. Can you provide us with more information regarding your scenario. Which version of IIS do you use, do you upload large or small files, is the area inside UpdatePanel/AjaxPanel?
