SchedulerControl.QueryResourceColorSchema Event

Enables visible resources to be painted according to certain conditions.

Namespace:DevExpress.XtraScheduler
Assembly:DevExpress.XtraScheduler.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type QueryResourceColorSchemaEventArgs containing data related to this event.

Expanded Remarks

By default, if you change a set of visible resources (for example, by using resource filter controls) the collection of resource color schemas will remain unchanged (GetResourceColorSchemasCopy), i.e. the same color schemas in the same order will be used to paint resources newly selected for display in the scheduler.

However, you can assign a specific color schema to each resource to be displayed. To do this, handle the QueryResourceColorSchema event.

The QueryResourceColorSchema event is raised before a resource to be displayed in the scheduler is painted. The event parameter's DevExpress.XtraScheduler.QueryResourceColorSchemaEventArgs.Resource property provides information on a processed resource. To associate this resource with a required color schema, use the DevExpress.XtraScheduler.QueryResourceColorSchemaEventArgs.ResourceColorSchema property.

The QueryResourceColorSchema event can be helpful, if it is required to paint resources according to certain conditions (for example, to highlight a selected resource or specify a certain color schema for a resource, depending on its custom field value, etc.).

Expanded Example

This example demonstrates how to link a specific SchedulerColorSchema to each visible resource.

Call the GetResourceColorSchemasCopy method to obtain a collection of color schemas that are currently available for resource coloring (according to the currently active skin) and handle the QueryResourceColorSchema event to associate a specific color schema from the obtained collection to each resource displayed in the scheduler control.
