  hi,

  you can see the AbpAuditActionFilter . This is a good example and entry point of how to implement an action filter. And you can add your filter here <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/blob/299b8f59e118c11425bc467d9e54ab4e1232918d/src/Abp.AspNetCore/AspNetCore/Mvc/AbpMvcOptionsExtensions.cs">https://github.com/aspnetboilerplate/as ... ensions.cs</a>

  Hey alper, thanks for the reply, we're using Asp.Net MVC 5 not Core.

  Can you please explain or provide an example for Asp.Net MVC 5?

  Thank you!

  Hey all, in case anyone needs, also for checking of best practices I did the following:

  [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]
      public class TestAttribute : ActionFilterAttribute, ITransientDependency
      {
          private ITestAppService _iTestAppService;
          private IAbpSession _session;
  
          public TestAttribute() : this(IocManager.Instance.Resolve<ITestAppService>(), IocManager.Instance.Resolve<IAbpSession>())
          {
          }
  
          public TestAttribute(ITestAppService service, IAbpSession session)
          {
              _iTestAppService = service;
              _session = session;
          }
  
          public override void OnActionExecuting(ActionExecutingContext filterContext)
          {
              if (filterContext.Controller.GetType() == typeof(SpecificController))
              {
                  if (_iTestAppService.GetTestItemByUserId(_session.UserId.Value).TestListCheck.Count == 0)
                  {
                      filterContext.Result = new RedirectResult("RedirectToSpecificPage");
                  }
                  base.OnActionExecuting(filterContext);
              }
          }
      }
  

  I added this Attribute Class to a Filters directory within the area it's being used.

  Then just added the attribute to the actions where restriction was required.

  Please advise if there's a better practice way of achieving the same result.

  Thank you!
