Commented Issue: Unhandled exception [6146]

TomGiam — Wed, 25 Apr 2012 02:30:57 GMT

In FileUpload.cs there is an unhandled exception that I am now seeing. BTW, I did not see this until I upgraded from IE7 to IE8.
In IE7 the problem would manifest by occasionally a file not being uploaded and the progress bar would not move.
I would just stop the upload and try again, but now it gives an exception when the server eventually responds with a "Not found" message code 4004

I tried catching it using this in the method; private void ReadCallback(IAsyncResult asynchronousResult):
try
{
response = (HttpWebResponse)webrequest.EndGetResponse(asynchronousResult);
}
catch (Exception ex) //also tried catch (WebException)
{

if (resizeStream != null)
resizeStream.Close();
Helper.dispMessage("Network error: " + ex.ToString());
}

but it doesn't catch it, and the debugger display the offending line.
BTW, I am using the PHP server side code.

Thanks
Tom

I commented out the code from "try" until reader.close and it didn't affect the main functionality much.

Created Issue: Restarting doesn't? [12069]

Eric6eyser — Tue, 24 Apr 2012 22:11:18 GMT

If i close the connection/browser during an upload, then go back and select the same file, it correctly says the file exists, i elect to CONTINUE but it appears to restart anyway. particularly evident with large files.
anyone else tried this?

Hi Tom, I'm having the same problem. Did you managed to find any resolution to your issue?

Created Issue: rounded corners do not use transparent underlying corner [11842]

mkamoski — Mon, 05 Mar 2012 15:04:54 GMT

Dear Silverlight File Upload Developer(s) -- This is a "minor bug" report. The rounded corners do not use transparent underlying corner, which means that if the corners appear as "white" if, for instance the control is on a gray background. I tried setting "backcolor" on the control; but, that did not help. I have attached a screenshot to help illustrate the issue. This could be fixed, probably, by using transparency, I guess. Anyway, it is a small "bug" but a bug nonetheless. HTH. Thanks. -- Mark Kamoski

Commented Issue: MaxNumberToUpload is set only once. Count for the same is not updated if user deletes the file [5643]

belarussianby — Tue, 25 Oct 2011 14:00:21 GMT

MaxNumberToUpload specifies the no. of files that can be allowed for the user to upload. If I set it to 1 and then try and upload a file, it allows me to do so. Now, if I remove the added file and then try to upload some other file, the control gives me a pop-up saying: "You have exceeded the total allowable number of files to upload.". This is because, when we click on the cross button "x" in the FileUploadRowControl, the count of files currently present in the control to upload is not updated accordingly, which gives rise to this issue. This can be modified to track the actual no. of files being uploaded during a single operation.
Comments: ** Comment from web user: belarussianby **

Oups!!!

Update:

easiest way to modify single file delete is just to put counter++ in the end of "Add files" button click event after file was added to the array:

files.Add(upload);

// File was added -> counter update
count++;

Before check if number of files added more allowed to upload add this line:

// Check if added file exceeds total number of allowed files.
count = files.Count + 1;

Do not need to create public property or variable in FileUpload class!!!!

Found a source of probleme:

FileUploadControl has variable called counter which is declared as global variable for the current FileUploadControl class - private int count = 0;
This variable is never reset when click on "Clear" button or "Remove file" image in the grid. To fix this just add counter=0 to "Clear" button event.

For removing single file we need to decriment variable. A problem is that event is in the FileUpload class. So to fix this issue we need to :

1) Create public property or variable in FileUpload class.
2) On "Remove" button click event decriment created variable
3)

Created Issue: webrequest content type and potentially dangerous request [10138]

rekna — Wed, 19 Jan 2011 15:09:12 GMT

In my opinion webrequest.contenttype should be "multipart/form-data"
inside StartUpload method of Vci.Silverlight.FileUploader

otherwise, with MVC3 and .NET 4 you get the error about a potentially dangerous request.

Commented Issue: Not working in opera browser [9335]

Eshva — Mon, 22 Nov 2010 13:14:30 GMT

When i use the control in opera, it gets stuck while uploading the first image.(it never shows the completed icon).
Comments: ** Comment from web user: Eshva **

I tried to recompile projects for SL 4.0 and .NET 4.0 to try to solve this problem (sometimes it helps 'couse SL 4.0 supports Opera better), but with no luck. SL control reports about 3 MB is uploaded, the file on server is 4 MB in size.

Created Issue: ByteConverter doesn't work correctly [5592]

oivoodoo — Fri, 18 Sep 2009 12:28:13 GMT

Hi, Guys.
I am using your component in sharepoint portal and it's great. I am very thankfull to you.

But I found some defect, please review it:

Please add double cast for byteCount because default cast for this step is integer and user can't see float part of byteCount.

Correct code:

(double) byteCount / ...

if (byteCount >= 1073741824)
size = String.Format("{0:##.##}", (double) byteCount / 1073741824) + " GB";
else if (byteCount >= 1048576)
size = String.Format("{0:##.##}", (double) byteCount / 1048576) + " MB";
else if (byteCount >= 1024)
size = String.Format("{0:##.##}", (double) byteCount / 1024) + " KB";
else if (byteCount > 0 && byteCount < 1024)
size = "1 KB"; //Bytes are unimportant ;)

With The Best Regards,
Alexander

Created Issue: Image resizing behaviour [5571]

andyste1 — Thu, 10 Sep 2009 14:37:58 GMT

Hi

I'm after a SL control to resize jpeg images before uploading to the server, so SilverlightFileUpload seems to fit the bill. I am setting ImageSize="48" and ResizeImage="True", but the resulting image is 48x48 pixels. It would have been nicer if the aspect ratio could be maintained, i.e. the ImageSize value is applied to the image's longest side (rather than both sides).

Just a suggestion for a future version (unless I'm missing some way of doing this).

Thanks in advance
Andy

Commented Issue: Cancelling the Upload Leaves Partly-Uploaded File

pcongdon — Mon, 31 Aug 2009 15:17:28 GMT

I must admit that I'm using the APIs of the FileUpload directly and not the control but I'm guessing this behavior exists for both.

If I cancel a file upload part way through then I'm left with a half-baked file on the server. Is there a simple way to know that the connection was broken (on the server) so that the file can be deleted? I'm also not sure how resume works (maybe this is why files are left behind?).

Thanks!
Kevin
Comments: ** Comment from web user: pcongdon **

In testing this solution, I selected a large file (about 2.5 G) for upload. I then cancelled the upload at about 380k. When I came back later and uploaded the same file I was prompted with "File Exists" message and allowed to continue the upload. However, what was uploaded to the web site was, in size, only about 1.4 G, not the complete file.

Then I removed the uploaded partial file and tried again with the same file and let it finish. This time it completed the upload and the file sizes matched.

Anyone else seen this behavior in testing the solution? I thought at first it only uploaded the size difference but the math doesn't work out ... :)

I hope that remained file chunks means resuming enabled. If not, the component works bad. :(
