Error Handling in MVC View

Sri Ram

I would like to know the right way of handling technical errors caused due to the in-line code in MVC Views. It could be due to ignorance of null check for an object before usage or some other reasons.

We use a BaseController class to handle all the errors related to each controller action method.

However, as we write in-line c# codes in views, how to appropriate handle these errors? what are the options available?

Simply add the [HandleError] attribute to the top of your Controller class. This way, any exception generated by your Controller will be handled and the user will be presented /Views/Shared/Error.aspx. The model passed to that view is a System.Web.Mvc.HandleErrorInfo object.
The controller:
[HandleError]
public class MyController : Controller
{
  public ActionResult Default()
  {
    MyClass thing = MyClassFactory.Create();
    return View(thing);
  }
}
This is a for "last resort" exception handling. David's answer is best for those cases you can think of ahead of time.
OR use this code
[HandleError]
public ProductsController
{
    public ActionResult Show(int id)
    {
        Product p = //e.g. get product from db

        if (p == null)
        {
            return RedirectToAction("Error");
            //return RedirectToAction("InvalidProduct");
        }

        return View(p);
    }
