Silverlight Rendering

[ankit]

How can i render new report, on a click command. Like a refresh button.

Which function in the Silverlight ReportViewer can be used to request new report, I was not able to find any render Function.

Hello ankit,

You can use the Report property of the Silverlight viewer to specify a new report i.e.:

private void button1_Click(object sender, RoutedEventArgs e)
        {
            this.ReportViewer1.Report = "Telerik.Reporting.Examples.CSharp.BarcodesReport, CSharp.ReportLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null";
        }

Kind regards,

I have already assigned the ReportViewer.Report.

I just want it to reload or fetch the new data from the database..

Isn't re-fetch or reload command in the ReportViewer of silverlight

Hello ankit,

Here is a sample snippet that illustrates how to invoke RefreshReport :

Copy Code

Copy Code

public partial class MainPage : UserControl
{
    public MainPage()
    {
        InitializeComponent();
    }

    void button1_Click(object sender, RoutedEventArgs e)
    {
        this.ReportViewer1.RefreshReport();
    }
}

static class ReportViewerExtensions
{
    public static void RefreshReport(this ReportViewer reportViewer)
    {
        var layoutRoot = (FrameworkElement)VisualTreeHelper.GetChild(reportViewer, 0);
        var viewerModel = (ReportViewerModel)layoutRoot.DataContext;
        var refreshCommand = viewerModel.RefreshReportCommand;
        if (refreshCommand.CanExecute(null))
        {
            refreshCommand.Execute(null);
        }
    }
}
