Can I change the default preview drop down amount?
Using the API you are able to custom code the amount of records the default preview returns in both the Report Designer & Report Viewer screens.
Note: Izenda does not recommend setting
this to a large number such as 5000 or larger as the HTML report will
take a long time to generate. If you would like to view all the data we
recommend exporting the report which always provides the entire report.
public override void ConfigureSettings()
{
AdHocSettings.DefaultPreviewResults = 500;
AdHocSettings.ReportViewerDefaultPreviewResults = 500;
}
