SL Viewer error handling

[Jon]

Hi..
Can you provide a sample or direction of how to implement error handing on a report - rendered in the SL viewer.
thx again!

Hi Jon,

You can do it similar to the following code snippet:

public partial class MainPage : UserControl, IReportServiceClientFactory
{
    public MainPage()
    {
        InitializeComponent();
        this.ReportViewer1.ReportServiceClientFactory = this;
    }

    #region IReportServiceClientFactory Members

    ReportServiceClient IReportServiceClientFactory.Create(Uri remoteAddress)
    {
        ReportServiceClient client = new ReportServiceClient(remoteAddress);
        client.RenderAndCacheCompleted += new EventHandler<RenderAndCacheEventArgs>(client_RenderAndCacheCompleted);
        return client;
    }

    void client_RenderAndCacheCompleted(object sender, RenderAndCacheEventArgs e)
    {
        if (e.RenderingResult.HasError)
        {
            e.RenderingResult.Error = "My custom error message";
        }
    }

    #endregion
}

As you can see the MainPage contains a Silverlight ReportViewer. On other hand, the viewer uses IReportServiceClientFactory to get a reference to the proxy of the WCF Report service. In the example we simply return the default implementation which is the ReportServiceClient. ReportViewer uses the RenderAndCacheAsync method to render the report. You can hook to the RenderAndCacheComplete event in order to implement a custom error handing for a report.


All the best,
