PermissionSettingHelper.AddObjectPermission<T>(IPermissionPolicyRole, String, String, Nullable<SecurityPermissionState>) Method

Finds the first type permission for the specified type in the role and adds the object permission to it. If the appropriate type permission is not found, this method creates it.

Namespace: DevExpress.ExpressApp.Security

Assembly: DevExpress.ExpressApp.Security.v24.2.dll

#Declaration

public static IPermissionPolicyObjectPermissionsObject AddObjectPermission<T>(
    this IPermissionPolicyRole role,
    string operations,
    string criteria,
    SecurityPermissionState? state
)
    where T : class

#Parameters

role IPermissionPolicyRole

The target role for a new object permission.

operations String

The semicolon-separated list of security operations. The static SecurityOperations class defines operation names and their delimiter.

criteria String

The criteria expression that specifies the target object(s).

state Nullable<SecurityPermissionState>

A SecurityPermissionState enumeration value that specifies if access is granted or denied.

#Type Parameters

Name Description
T

This method finds the type permission for this type in the role.

#Returns

Alternatively, you can use the AddObjectPermissionFromLambda<T>(IPermissionPolicyRole, String, Expression<Func<T, Boolean>>, Nullable<SecurityPermissionState>) method, which takes a lambda expression instead of a criteria expression.
