property PropertiesList.ShowNonBrowsable as Boolean

Retrieves or sets a value that indicates whether the control displays the non browseable members.

TypeDescription
Boolean A boolean expression indicating whether the control displays the non browseable members.

Use the ShowNonBrowsable property to include non browseable members. Changing the ShowNonBrowsable property at runtime invokes refreshing the control. 

Here's a sample that shows how to include only hidden members:

Private Sub PropertiesList1_IncludeProperty(ByVal Property As EXPROPERTIESLISTLibCtl.IProperty, Cancel As Boolean)
    Cancel = Not (Property.Flags And &H40) = &H40
End Sub
