Remarks
Important
This overload of the CanRead
method may reduce performance and cause incorrect behavior in some usage scenarios. We recommend that you always use the CanRead
method’s overloads that accept an Object Space as a parameter to check permissions for a specific object.
The following example shows how to use this method.
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Security;
using System;
// ...
public class CheckReadPermissionController : ObjectViewController<ListView, Contact> {
SecurityStrategy securityStrategy;
protected override void OnActivated() {
base.OnActivated();
securityStrategy = Application.GetSecurityStrategy();
View.CurrentObjectChanged += View_CurrentObjectChanged;
}
private void View_CurrentObjectChanged(object sender, EventArgs e) {
Department department = ViewCurrentObject.Department;
if (department!= null && !securityStrategy.CanRead(department, nameof(Department.Office))) {
// ...
}
}
}
