DayRenderEventArgs Class

Provides data for the DayRender event of the Calendar control. This class cannot be inherited.

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

public sealed class DayRenderEventArgs
public final class DayRenderEventArgs
public final class DayRenderEventArgs
Not applicable.

Although data binding is not supported for the Calendar control, it is possible to modify the content and formatting of the individual date cells. Before the Calendar control is displayed on the Web page, it creates and assembles the components that make up the control. The DayRender event is raised when each date cell in the Calendar control is created. You can control the contents and formatting of a date cell when it is created by providing code in the event handler for the DayRender event.

The event handler receives a DayRenderEventArgs object that contains event data. Use the Cell property to access the cell being rendered. To access the properties of the day being rendered, use the Day property. When customizing the content for a cell, you might want to preserve the postback behavior when the user selects the date being rendered. This is typically done by rendering the script used to post the page as part of the custom content. To retrieve the script used to post the page back to the server, use the SelectUrl property.

For a list of initial property values for an instance of DayRenderEventArgs, see the DayRenderEventArgs constructor.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to specify and code a handler for the DayRender event to make the background color yellow for the days in the displayed month. It also demonstrates how to customize the contents of a cell by adding a System.Web.UI.LiteralControl control to the cell.
