Namespace: DevExpress.Persistent.BaseImpl.PermissionPolicy

Assembly: DevExpress.Persistent.BaseImpl.Xpo.v24.2.dll

NuGet Package: DevExpress.Persistent.BaseImpl.Xpo

Declaration

C#

[Association]
public XPCollection<PermissionPolicyRole> Roles { get; }

Public ReadOnly Property Roles As XPCollection(Of PermissionPolicyRole)

Property Value

Type	Description
XPCollection<PermissionPolicyRole>	An XPCollection<PermissionPolicyRole> collection which is the list of roles associated with the current user.

Remarks

In XAF applications, permissions are not assigned to a user directly. Users have roles, which in turn are characterized by a permission set. So, each user has one or more roles that determine what actions can be performed.

An example of using this property is provided in the Client-Side Security (2-Tier Architecture) topic.
