I also have a small question:
I add event handler to RenderBegin event to update my parameters when I render report:

private void ReportViewerCompaignRenderBegin(object sender, RenderBeginEventArgs args)
        {
            if (DateFrom > DateTo)
            {
                DateTo = DateFrom;
            }
            args.ParameterValues.Clear();
            args.ParameterValues.Add("TimeInterval", TimeInterval.ToString());
            args.ParameterValues.Add("DateFrom", DateFrom);
            args.ParameterValues.Add("DateTo", DateTo);
            args.ParameterValues.Add("Publication", Publication);
        }

When ReportViewer is initializing - it read this parameters well, but when I try refresh report with method:

public void Draw()
        {
            ((ReportViewerModel) (DataContext)).ApplyReportParametersCommand.Execute(null);
        }

It doen't update report parameters. Can you help me some way?
