This is a crazy, crazy annoying bug. Basically, when the Crystal Windows Form Viewer is added, the auto-generated code adds two lines that will overwrite the selection formula!!!

Resolution

To resolve the issue, follow these steps:

Expand Form1.vb|cs to show Form1.Designer.vb|cs. (form1 denotes the form that contains your viewer)

Double-click on Form1.Designer.vb|cs to show its code.

In the InitializeComponent method, you will find code where the CrystalReportViewer1 properties are set.

Comment out or delete the following two lines:

me.crystalReportViewer.SelectionFormula = ""

me.crystalReportViewer.ViewTimeSelectionFormula = ""
