How to download the GP executed result?

Question

Hi,

I want to build a GP service to allow the end user zip several selected shapefile on the fly and download the zip file afterwards. The problem is that what the Parameters should I reference the OutPut parameter to in the ArcToolBox property tab??a Record Set??Also, after GP service execution, the result in the code is a GPParameter object, but what will be the exact object type for the GP output in C# code?  How can I link the result object in C# to a hyperlink button or how to automatically popup a download dialog box when the zip file is ready?

Thanks,

Wei

Once the output is of type GPDataFile.

You can have the following XAML-code:
        <HyperlinkButton x:Name="link" Content="{Binding Name}" 
                         NavigateUri="{Binding Url}"
                         VerticalAlignment="Top" HorizontalAlignment="Center"/>

link.DataContext = gpParameter as GPDataFile;
