1613585 - Why does my Crystal Report preview show the days of the week and names of colours?


  • Previewing a Crystal Report in the embedded report designer in Visual Studio 2010.
  • Instead of showing the correct report data, random numbers or days of the week or names of colours are displayed?
  • Why does the random data get displayed?



  • Visual Studio 2010
  • Crystal Reports for Visual Studio 2010


  • The random data is displayed because there is no valid data available for the preview.
  • This is most often done when the ADO.NET (XML) driver is used because the embedded designer has no way of getting data from the DataSet.
  • The random data is used intentionally written so the report designer can get an idea of how their report will look.
  • This is not an issue at runtime in the application.


  • Preview the report in the application using the CrystalReportViewer - Winform, webform or WPF viewer.
    • This will use live data from the SetDataSource method.
  • Design your report on a .xml file which includes data and a schema. The .xsd file contains no data, so random data is used instead.
