Hello,

i got a not exspected behavior while using the Radupload Control for Silverlight.

I configured RadUpload control with these settings:

IsAutomaticUpload="True"
IsMultiselect="False"
OverwriteExistingFiles="True"
IsAppendFilesEnabled="False"
MaxFileCount="1"

therefore it should be possible to upload one single file only . If I selected the file via the OpenFileDialog uploading starts as exspected.
The problem is now: the Upload Button occurs and I can start uploading the selected file again.
The result of this action is: Progressbars (File and Overall) does not match anymore and is flickering. Progressbar is beyond 100%. File is uploaded and will be overwritten by the same file again.


I use Radupload Version: 2010.3.1110.1040
Telerik.Windows.Controls Version: 2010.3.1110.1040
and Telerik.Windows.Controls.Input Version: 2010.3.1110.1040

with RadUploadHandler Version: 2010.3.1110.35

I tried a previos version of the RadUpload Control (Ver. 2010.2.924.1040)  that works as exspected (not beeing able to start upload 2 times, cause Pause Button and not Upload Buttons is shown).

See attachment with a VS2010 demo solution to reproduce the error and some pictures which shows the errors:
Step 1 to 4 Pictures.
Rename .png to .rar to unzip Files.

Update:  File Upload failed, therefore i will upload pictures only.

Merry Christmas and kind regards

Hi Akiono Wan,

Thank you for reporting this. I was able to reproduce this issue. We have made some changes around the UI related code of the RadUpload and this was a side product of this. The state was incorrectly updated when automatic upload was enabled. I have already resolved this and updated your Telerik points accordingly. The resolution will be available with the next internal build.

Using the RadUpload for the first time. I have set MaxFileCount="1", and I am not seeing an error when I attempt to upload a second file. The documentation indictaes I should see a "  a notification icon and a tooltip with an error message " . 

Hi Nathaniel,

 Are you uploading two files separately or you are uploading them in a bundle at once? The MaxFileCount property only relates to the number of files that can be uploaded at once, not generally.
