Calendar.VisibleDate Property

Gets or sets the DateTime value that specifies the month to display on the Calendar control.

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

public DateTime VisibleDate { get; set; }
<asp:Calendar VisibleDate="DateTime" />

Property Value

Type: System.DateTime
A System.DateTime value that specifies the month to display on the Calendar. The default value is DateTime.MinValue, which displays the month that contains the date specified by TodaysDate.

Use the VisibleDate property to programmatically set the month to display on the Calendar control. The specified date can be any date in the month you want to display, although it is common to use the first date in the month. This property is set using a System.DateTime object.

The VisibleDate property is updated before the VisibleMonthChanged event is raised. You can provide a custom OnVisibleMonthChanged event handler to set the VisibleDate property and override the automatically generated value.

The following code example demonstrates how to use the VisibleDate property to programmatically set the value that determines the month that is displayed in the Calendar control.
