    <p>I am trying to get my MVC3 application to display the validation messages of RequiredIfs, using the attribute from here: <a href="http://blogs.msdn.com/b/simonince/archive/2011/02/04/conditional-validation-in-asp-net-mvc-3.aspx" rel="nofollow">http://blogs.msdn.com/b/simonince/archive/2011/02/04/conditional-validation-in-asp-net-mvc-3.aspx</a> Now it works fine if there are no child entities, but I have a user, and that users address object needs to be validated. Well actually even one address would work, but there are 3 addesses, each has a checkbox that indicates whether it is active or not.</p> <p>I tried changing the jQuery of the validator.unobtrustive.js as following to get the correct value on validation (address is either 'Address_' or 'BillingAddress_':</p> <pre><code>$.each(this.params, function () { var address = element.name.split('.')[0] + '_'; paramValues[this] = this.toString() == 'dependentproperty' ? address + $element.attr(prefix + this) : $element.attr(prefix + this); }); </code></pre> <p>This only works when all possible checkboxes that a RequiredIf depends on is checked. The following validates all addesses and gives outputs the messages on the view:</p> <pre><code>$.each(this.params, function () { paramValues[this] = this.toString() == 'dependentproperty' ? 'Address_' + $element.attr(prefix + this) : $element.attr(prefix + this); }); </code></pre> <p>Any help or ideas why it is behaving this way are welcome =) Other approches to solve the problem I'll happily accept. Thanks for your help.</p> <hr> <p>Edit</p> <p>I realized that the javascript stuff doesn't work anyways and am now already getting the correct ID from the model. But I still have the error that it only validates when all the checkboxes are checked. Any ideas why that is?</p> <p>The Model for an Address is built as following:</p> <pre><code>[RequiredIf("IsActive", true)] [Display(Name = UserManagementResources.sdAddressText, ResourceType = typeof(UserManagementResources))] public string Street { get { return _address["sdAddress"]; } set { _address["sdAddress"] = value; } } [RequiredIf("IsActive", true)] [Display(Name = UserManagementResources.sdCityText, ResourceType = typeof(UserManagementResources))] public string City { get { return _address["sdCity"]; } set { _address["sdCity"] = value; } } </code></pre> <p>The ViewModel contains the different addresses.</p> <pre><code> public Address Address { get { return _address ?? (_address = new Address(Customer.Name, _domain, "Address") { IsActive = true }); } } public Address BillingAddress { get { return _billingAddress ?? (_billingAddress = new Address(Customer.Name, _domain, "BillingAddress")); } } </code></pre> <p>The controller simply creates a new Empty Model. The view displays the different addresses using a Html.EditorFor().</p> <hr>

    1. COCan you post your (or a simplified) Model and Controller? I'm guessing the validation is preventing the child objects from being created and therefore conditionally validated, but we're working a little blind.

    2. COI posted the main parts of the model as an edit. The controller really doesn't do anything except pass on the ViewModel...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
