C# Class Habanero.Faces.VWG.DateRangeComboBoxVWG

Provides a selection of common date range options which a user can select from, modifying a start date and end date depending on the selection. The options to choose from, such as "Yesterday", "Last Week" or "This Year", can be modified by the developer. When adding this control, add an event handler on the SelectionChangeCommitted event, and obtain the StartDate and EndDate properties at this time.
NOTE: The start and end dates are the two boundaries of a potential range. Whether they should be inclusive or exclusive depends on the developer and how they are implemented. For instance, if today is Nov 13, Yesterday would provide a start date of Nov 12, 12am and an end date of Nov 13, 12am.
To add additional menu options that aren't available, simply add the new text item to the ComboBox, using Items.Add. When you pick up the SelectionChangeCommitted event, check if the new text string is selected in the Text property and use your own calculations instead of fetching the StartDate and EndDate.
