      RadControls for ASP.NET AJAX RadScheduler has two properties for maintaining information about custom resources: ResourceTypes is a collection of ResourceType
objects. Each ResourceType object holds the information needed to define a resource type,
including the Name of the resource type, the DataSource or
DataSourceID, KeyField, and TextField
values needed to fetch a list of possible values for the resource type, and the ForeignKeyField
needed to store resource values with an appointment. ResourceType also includes an
AllowMultipleValues property, which a provider uses to indicate that multiple values
of that resource type can be assigned to a single appointment. Resources is a collection of Resource objects.
Resources has a method, GetResourcesByType, that you can use to
filter the collection to list only those resources of a specific resource type. Each Resource
object represents a possible value of a resource type. The Resource objects have a Key
property, which is stored with the appointment, a Text property, which is the text
representation of the resource value, and a Type property, which is the name of the
resource type for which it is a value. Resource objects also have an Available
property, which determines whether the edit form includes the resource value in the list of possible values that it displays to the user.
Each Appointment object also has a Resources property, which is a
collection of Resource objects that is assigned to the appointment. When working with the
Resources property of an appointment, use the GetResourceByType
method to obtain a reference to the single value of that resource type that is assigned to the appointment. If the
resource supports multiple values for a single resource type, you can use the GetResourcesByType method instead. ExampleThis example shows how to use the Available property to control the availability of a resource.
This property is cleared on each data binding, so the list of available resources must be maintained separately from the scheduler.  CopyC#
private const string UsedResourcesSessionKey = "Telerik.Web.Examples.Scheduler.ResourceAvailability.DefaultCS";
private List<Resource> UsedResources
{
get
{
List<Resource> resources = Session[UsedResourcesSessionKey] as List<Resource>;
if (resources == null)
{
resources = new List<Resource>();
Session[UsedResourcesSessionKey] = resources;
}
return resources;
}
}
private void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
UsedResources.Clear();
}
}
private void ReserveResources(ResourceCollection resources)
{
foreach (Resource res in resources)
{
if (!UsedResources.Contains(res))
{
UsedResources.Add(res);
}
}
}
private void FreeResources(ResourceCollection resources)
{
foreach (Resource res in resources)
{
if (UsedResources.Contains(res))
{
UsedResources.Remove(res);
}
}
}

{
foreach (Resource res in RadScheduler1.Resources)
{
res.Available = !UsedResources.Contains(res);
