DxSchedulerResourceMappings Class

Maps the resource’s properties to the data source fields.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor


public class DxSchedulerResourceMappings :

The following members return DxSchedulerResourceMappings objects:


Follow the steps below to add and assign resources to Scheduler appointments:

  1. Use the constructor without parameters to create a DxSchedulerDataStorage object. See the DxSchedulerAppointmentMappings class description for more information.
  2. Declare a class that stores resource options (for instance, ResourceObject).
  3. Create a collection of resource source objects (ResourceObject class instances) and define their options:
    • Id - Specifies the resource’s unique identifier.
    • Caption - Specifies the resource’s caption.
    • Color - Specifies the resource’s color. To apply this color to all appointments that correspond to the resource, remove appointment labels.
    • BackgroundCssClass - Specifies the CSS class applied to the resource’s background (the background color, background image, border color, and so on). Note that the Color property value overrides the background color specified in the CSS class.
    • TextCssClass - Specifies the CSS class applied to the text of appointments that correspond to the resource.
  4. Assign the newly created collection to the storage’s ResourcesSource property to fill the storage with a collection of data objects. The Scheduler generates a resource item (DxSchedulerResourceItem) for each item in this collection.
  5. Assign a new DxSchedulerResourceMappings object to the DxSchedulerDataStorage.ResourceMappings property. In this object, map the data source fields to appointment properties.
  6. Optional. Group appointments by resource. To do this, set the Scheduler’s GroupType property to SchedulerGroupType.Resource.
<DxScheduler StartDate="@DateTime.Today"
        <DxSchedulerDayView DayCount="3"
                            TimeScale="@(new TimeSpan(1,0,0))"
                            WorkTime="new DxSchedulerTimeSpanRange(TimeSpan.FromHours(9), TimeSpan.FromHours(18))"
                            VisibleTime="new DxSchedulerTimeSpanRange(TimeSpan.FromHours(8), TimeSpan.FromHours(19))"
        <DxSchedulerWeekView ShowWorkTimeOnly="true" />
        <DxSchedulerWorkWeekView ShowWorkTimeOnly="true" />
        <DxSchedulerTimelineView  />

@code {
    DxSchedulerDataStorage DataStorage = new DxSchedulerDataStorage() {
        AppointmentsSource = ResourceAppointmentCollection.GetAppointments(),
        AppointmentMappings = new DxSchedulerAppointmentMappings() {
            Type = "AppointmentType",
            Start = "StartDate",
            End = "EndDate",
            Subject = "Caption",
            AllDay = "AllDay",
            Location = "Location",
            Description = "Description",
            LabelId = "Label",
            StatusId = "Status",
            RecurrenceInfo = "Recurrence",
            ResourceId = "ResourceId"
        ResourcesSource = ResourceCollection.GetRecources(),
        ResourceMappings = new DxSchedulerResourceMappings() {
            Id = "Id",
            Caption = "Name",
            Color = "Color",
            BackgroundCssClass = "BackgroundCss",
            TextCssClass = "TextCss"

If you do not need to display all of the resources from the data source, use the VisibleResourcesDataSource property to specify visible resources.

Resource’s Custom Fields

You can add custom properties to a resource:

  1. Define custom fields in the resource’s source object.
  2. Add created fields to the CustomFieldMappings collection.

The code below adds the MyCustomField field to ResourceObject and maps this field to the resource’s MyCustomProperty property:

@code {
    public class ResourceObject {
        public int Id { get; set; }
        public string LabelName { get; set; }
        public System.Drawing.Color LabelColor { get; set; }
        public string MyCustomField { get; set; } // a custom field

    DxSchedulerDataStorage DataStorage = new DxSchedulerDataStorage() {
        ResourcesSource = new List<ResourceObject>() {
            new ResourceObject() { 
                Id = 1, 
                ResourceName = "Resource One", 
                ResourceColor = System.Drawing.Color.Aqua, 
                MyCustomField = "custom text for Resource One" 
            new ResourceObject() { 
                Id = 2, 
                ResourceName = "Resource Two", 
                ResourceColor = System.Drawing.Color.Beige, 
                MyCustomField = "custom text for Resource Two"
        ResourceMappings = new DxSchedulerResourceMappings() {
            Id = "Id",
            Caption = "ResourceName",
            Color = "ResourceColor",
            // Map the source object's custom field to the resource's custom property
            CustomFieldMappings = new List<DxSchedulerCustomFieldMapping> {
                new DxSchedulerCustomFieldMapping { Name = "MyCustomProperty", Mapping = "MyCustomField" }
