    <p>I made a validation method for business rules that are not verified from my rules in the model, but I'm having a problem to make it work. Since there are two possible scenarios(customer or seller registration), they need to be treated separately in their own views and models. The seller registration inherits from customer registration for the basic info, so all fields in customer are also in seller. But since I'm working with 2 different models, even though both have the same fields that I'm doing the validation upon, I needed to use <code>Object</code> to use the same validation method. But unfortunately I'm having trouble to do so.</p> <pre><code>[CustomHandleError] private bool ValidateRegistrationForm (Object registerViewModelObject) { if (registerViewModelObject is RegisterViewModel) { RegisterViewModel registerViewModel = (RegisterViewModel)registerViewModelObject; } else { RegisterSellerViewModel registerViewModel = (RegisterSellerViewModel)registerViewModelObject; } if (ModelState.IsValid) { string [] names = registerViewModel.Name.Split ( new string [] {" "}, StringSplitOptions.RemoveEmptyEntries); if (names.Length == 1) ModelState.AddModelError ("Name", "Fill your full name"); if (CustomerUtilities.IsCpf (registerViewModel.Identity) == false) ModelState.AddModelError ("Identity", "Invalid CPF value"); if (this.AuthenticatorService.IsExistentUser (registerViewModel.Email)) ModelState.AddModelError ("Email", "Email already registered"); } } </code></pre> <p>As you can see, after the <code>if (ModelState.IsValid)</code> the IntelliSense doesn't find registerViewModel in the current context. I wonder why this happens, since that variable is defined inside the if AND the else above, so there is no way to reach that code without it being defined. </p> <p>Is there any workaround for this(other than creating a new method or passing 2 variables)?</p>

    1. COPaste your code here as a text, not as an image.

    2. COPasting the code as a code block will allow you to get better answers, since it will be easier to produce a correct example for you.

    3. COThe quick fix is to copy and paste the code in the if and else blocks. The issue is that there is no common base class for the registrations or that inheritance is not being used properly (a seller registration does not seem to be a kind of customer registration so inheritance will be awkward). You've got to do some design work to fix this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
