FirstDateOfGroup Property

Returns a Nullable that represents the first item of the group. Note, this will not be the first item displayed within the group if the group displays leading dates.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property FirstDateOfGroup As Nullable(Of Date)

C#

public Nullable<DateTime> FirstDateOfGroup {get;}

Remarks

The FirstDateOfGroup and LastDateOfGroup identify the range of dates that make up the group. These dates do not include any dates that would represent leading or trailing items. The values are calculated based on the ReferenceDate, ReferenceGroupOffset and the CurrentMode.

The property is nullable because it is possible that the group will not be able to display any dates. For example, if the MinDate and MaxDate were such that you could only see a year, if the Dimensions was 2,2 so that the control displayed 4 groups, not all the groups would be able to display items when you start zooming out.
