MonthChangedEventArgs.PreviousDate Property

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

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

public DateTime PreviousDate { get; }
/** @property */
public DateTime get_PreviousDate ()

public function get PreviousDate () : DateTime

Property Value

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

Use this property to determine the previously displayed month on the Calendar control. You can restore the Calendar control to the previously displayed month by setting the VisibleDate property to PreviousDate.

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

The VisibleDate property is updated to the date in this property before the VisibleMonthChanged event is raised.

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.

   <script runat="server">

      void MonthChange(Object sender, MonthChangedEventArgs e) 

         if (e.NewDate.Month > e.PreviousDate.Month)
            Message.Text = "You moved forward one month.";
            Message.Text = "You moved backwards one month.";

   <form runat="server">
