MonthChangedEventArgs.NewDate Property

Gets the date that determines the currently displayed month in the Calendar control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public DateTime NewDate { get; }
/** @property */
public DateTime get_NewDate ()

public function get NewDate () : DateTime

Not applicable.

Property Value

The date that determines the month currently displayed by the Calendar.

Use this property to get the month currently displayed by the Calendar control and to compare the currently displayed month with another month. For example, you can use this property to calculate the number of months until or since a certain date.

This date is normally the first date of the currently displayed month; however, it can be programmatically changed to any date within the month.

The VisibleDate property can be assigned to this property programmatically to override the month change when the user clicks the navigation controls for the Calendar control.

The following code example demonstrates how to compare the months of the NewDate property and the PreviousDate property to determine whether the Calendar control moved forward one month or backward one month.
