Hi Ted Bielenda,

You can hook on the OnClientFilesUploadStarted event provided by the Silverlight upload and then use a plug-in like jquery block to block the page. Then you can use the OnClientUploadFilesUploadFinished event to enable the page.

You can add handlers for the upper-mentioned events the following way:

uploadConfig.Add("OnClientFilesUploadStarted=" + "onClientUploadStarted");

uploadConfig.Add("OnClientFilesUploadFinished=" + "onClientUploadFinished");

Where the left param is the name of the event and the right is the name of the client-side handler.

Microsoft JScript runtime error: Unhandled Error in Silverlight 2 Application [Arg_NullReferenceException]

Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=4.0.50524.0&File=mscorlib.dll&Key=Arg_NullReferenceException   at Upload.Page.InvokeScriptObject(String functionName, Object[] args)

   at System.Windows.Controls.Primitives.ButtonBase.OnClick()
   at System.Windows.Controls.Button.OnClick()

Hi Genady Sergeev,

                         Thanks for sample,It is working, But I need same functionality with delete file options as mentioned in the attached image. And if i am using delete file option code like this javascript function, It is giving me java script error in IE and saying for debugging.
    
// Fired when a file is uploaded
           function onClientFileUploaded(json) {
               
               $get("<%=btnUpload.ClientID %>").disabled = "disabled";           
               var uploadedFile = Sys.Serialization.JavaScriptSerializer.deserialize(json);
               var downloadFile = $("<a class='download-file'></a>")
                .attr("href", '<%= ResolveUrl(TargetFolder) %>' + uploadedFile.FileName)
                .text(uploadedFile.FileName);
              
               var deleteFile = $("<a class='delete-file'>Delete</a>")
                .attr("href", "#")
                .click(function(e) {
                    e.preventDefault();
                                  
                    Array.remove(uploadedFiles, uploadedFile);
                  
                    updateHiddenField();
                    
                    
                    PageMethods.DeleteFile(uploadedFile.FileName);
                    $(this)
                        .parent()
                        .animate({ width: 0, opacity: 0 }, function() {
                            $(this).remove()
                        });
                }
                );
                
               $("<span class='uploaded-file'></span>")
                .append(downloadFile)
                .append(deleteFile)
                .appendTo($("div.uploaded-files"));

               Array.add(uploadedFiles, uploadedFile);
             
           }

Hello Ted Bielenda,

Thank you for the sample project. On my machine, it failed at this line:

updateHiddenField();

After I've added that function everything worked as expected. Could you please adding the following to your aspx page:

function updateHiddenField() {
                var json = Sys.Serialization.JavaScriptSerializer.serialize(uploadedFiles);
                $get('UploadedFilesJson').value = json;
            }
