Uploading mp3 files in Lightswitch HTML client

Question

Hello,

I'm trying to upload async a mp3 file in  lightswitch HTML with kind of progress bar.

I've seen some examples of how to upload files, but the files are like images that are fast to upload. Because this I'd like a progress bar to show the customer how long it will take.

Someone know how can I do it ?

Thank you ADefwebserver, I used an ashx files in a asynchronous methods, that return progress.

But I have one more question of your time.

I know you know  many things about Lightswitch, I have to rename this mp3 files with ID identity of database, is there any event after save or after commit ?

After you call SaveChanges() you can then get the ID of the record that was just saved. See:

Integrating PayPal With Visual Studio LightSwitch

 

                          // Associate the Picture to the PayPalTransaction
                            objPayPalTransaction.Picture = objPicture;

                            // Save the record so we get a Id to use in the PayPal request
                            serverContext.DataWorkspace.ApplicationData.SaveChanges();

                            // set PayPalPurchaseTransactionId
                            PayPalPurchaseTransactionId = objPayPalTransaction.Id;
