InitializeVisibleDay Event

Event fired before a VisibleDay object is added to the VisibleDays collection.
Syntax
'Declaration
 
Public Event InitializeVisibleDay As InitializeVisibleDayEventHandler
public event InitializeVisibleDayEventHandler InitializeVisibleDay
Event Data

The event handler receives an argument of type VisibleDayEventArgs containing data related to this event. The following VisibleDayEventArgs properties provide information specific to this event.

PropertyDescription
VisibleDay Returns the VisibleDay object for which the event has occurred.
Remarks

A reference to the VisibleDay that is about to be added is passed in the event args.

Example
This code sample demonstrates how to use the UltraDayView control's DayTextFormat and the VisibleDay object's Text property, in conjunction with the InitializeVisibleDay event, to customize the text that is displayed by the DayHeaderUIElement.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
