how to get TotalPages count after rendering ?

[Stephan]

Hi,

how can I extract the number of rendered pages from a Telerik.Reporting.Report ?
The idea is to check via a unit test if no empty pages are generated by a report.
(E.g. report with known data has 2 pages. Changing the layout later on causes an empty page. Report has now 3 pages, unit test detects this problem.)

Hello Marco,

In order to test for empty pages our suggestion is to use the ReportProcessor to render the report in image format with device info setting - StartPage set to 3. This way the RenderReport method will throw an exception if page 3 is unavailable. Thus you can fail the test if no exception is thrown as shown in the falling sample:

try
{
    var processor = new ReportProcessor();
    var reportSource = new InstanceReportSource();
    reportSource.ReportDocument = new ReportCatalog();
    var deviceInfo = new Hashtable();
    deviceInfo.Add("StartPage", 3);
    processor.RenderReport("Image", reportSource, deviceInfo);
    Assert.Fail("Empty page is rendered.");
}
catch
{
}
