Initializes a new instance of the DateTimeGroupDescription class.
public DateTimeGroupDescription()Properties
Gets or sets the step of the grouping. Items will be put in an IGroup with a Name based on the DateTimeStep. DayGroup. MonthGroup. QuarterGroup. YearGroup. WeekGroup. HourGroup - not auto generated by default. MinuteGroup - not auto generated by default. SecondGroup - not auto generated by default.
[DataMember]
public DateTimeStep Step { get; set; }Methods
When overridden in derived classes, performs type-specific cloning operations for the derived class properties. This method is called by CloneCore(Cloneable) after base properties have been copied.
protected override void CloneOverride(Cloneable source)The source object to clone from.
Overrides:
Notes to Inheritors: If you derive from Cloneable, you need to override this method to copy all properties. It is essential that all implementations call the base implementation of this method (if you don't call base you should manually copy all needed properties including base properties).
When implemented in a derived class, creates a new instance of the Cloneable derived class.
protected override Cloneable CreateInstanceCore()New instance for cloning.
Overrides:
Do not call this method directly (except when calling base in an implementation). This method is called internally by the Clone() method whenever a new instance of the Cloneable is created. Notes to Inheritors. Every Cloneable derived class must implement this method. A typical implementation is to simply call the default constructor and return the result.
Gets all possible group names by combining unique names from the data with calculated items. This method merges the actual data group names with any defined calculated items to provide a complete list of available groups.
protected override IEnumerable<object> GetAllNames(IEnumerable<object> uniqueNames, IEnumerable<object> parentGroupNames)The unique group names found in the actual data.
parentGroupNamesIEnumerable<object>The parent group names in the hierarchy.
Returns:IEnumerable<object>
A combined enumerable of unique names and calculated items.
Overrides:
Gets the unique name for this group description, which is the property name used for grouping. This unique name is used to identify and distinguish this group description from others.
public override string GetUniqueName()The property name that serves as the unique identifier for this group description.
Overrides:
Names a group that would contain the item.
DayGroup.
MonthGroup.
QuarterGroup.
YearGroup.
protected override object GroupNameFromItem(object item, int level)The item to group.
levelintThe level of grouping for this GroupDescription.
Returns:A name for the group that would contain the item.
