ASPxScheduler.HtmlTimeCellPrepared Event
Occurs when the HTML code representing the time cell is prepared for display.
Namespace: DevExpress.Web.ASPxScheduler
Assembly: DevExpress.Web.ASPxScheduler.v19.2.dll
Declaration
Event Data
The HtmlTimeCellPrepared event's data class is ASPxSchedulerTimeCellPreparedEventArgs. The following properties provide information specific to this event:
Property | Description |
---|---|
Cell | Provides access to the HTML table cell which represents the current time cell of the Scheduler. |
Interval | Gets the time interval which characterizes the current time cell. |
Resource | Gets the resource of a cell related to the ASPxScheduler.HtmlTimeCellPrepared event. |
View | Provides access to the Scheduler View. |
Remarks
The HtmlTimeCellPrepared event occurs before a time cell is rendered. Handling this event enables you to specify the style and color of a particular time cell, and even insert a Literal control to display text.
Note
Subscribing to the HtmlTimeCellPrepared event automatically disables client-side rendering of view elements.
The following code snippet uses the HtmlTimeCellPrepared event to highlight dinner time.
