SchedulerResourceHeaderCellInfo Class

Stores information about a resource header cell in the Scheduler.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public class SchedulerResourceHeaderCellInfo

Remarks

A SchedulerResourceHeaderCellInfo object is passed as the context parameter to resource header templates. Use the Intervals property to get intervals a resource header cell belongs. The Resource property specifies the resource associated with the resource header cell or contains an empty resource item if no resource is assigned.

The following example adds images to resource header cells:
