We are evaluating your Silverlight upload control and are trying to add a text field to each file selected in order for the user to specify any comments.

Does this product support such a scenario?

Regards

Hi Sean,

This feature is not available for the time being. We will log it in our To-Do list for further consideration. If the demand for this feature increases we will definitely include it in the control.

I also have a need for this feature. Even though the upload functionality in itself seems really good, the component is rather limited if we cannot specify metadata for each file. Ideally I would like to be able to specify the DataTemplate for the selected files, so that I can show a dropdown list or some textboxes or whatever for each file.

Hi hwsoderlund,

Attached you can find an example application where such an modification was implemented.

Please review following files:
  • MyUploadHandler.ashx.cs - here we extract the custom data sent under a custom upload parameter;
  • Page.xaml - here we initialize the RadUpload's ItemContainerStyle property with a new template for RadUploadItem. Please note the included TextBox with x:Name="CustomTag" - this is the place where you will enter your custom data for each one of uploaded files.
  • Page.xaml.cs - here we actually do some dirty jobs, especially:
    • uploaderTest_UploadStarted() - here we change all TextBoxes to look read-only;
    • uploaderTest_FileUploadStarting() - here we get the custom data under the uploaded file and send it as a custom upload parameter;
    • uploaderTest_FileUploaded() - here we change the foreground color of the TextBox to reflect the upload result - green for success and red if fail;
    • GetCustomTagControl() - very important - here we get access to the TextBox with custom data.
Please give it a try and let me know if more questions arise.

Best wishes,
Ivan

Please, notice this does not work with RadUpload latest build....

The code sample you have given here is a important. Actually I also needed to add text boxes when the files are selected. This example full fills that requirement. But we need to save the file with the name which will be given within the text box.
I was able to manage that thing within the "FileUploadStarting" event as below.

private

 

void uploaderTest_FileUploadStarting(object sender, Telerik.Windows.Controls.FileUploadStartingEventArgs e)

 

{

e.UploadData.FileName = "SampleName.pdf";
}


Problem: When a different name is given, the progress bar is not working in that solution. :(. Can you please give a solution for that ASAP. (Did yo notice it?????????????)

I love this, and can definitely use it, but I downloaded it today, and tried to run it.  It works fine for 1 file, but errors in FileUploadStarting if you upload 2 files with a cross-thread error.

Any chance of getting a new build of this, that works with the latest release and VS2010, and .Net 4 ?

Thanks,
Mark

Hi Mark,

Currently, this is a known issue for us. The RadUpload is handling the uploading of different files async and this event is being raised on different threads. We are still working on resolving this. This is logged in our PITS and you can check its progress from here.
