    <p>I am trying to create my own custom data annotations. I created a new project and the data annotations work perfectly in this clean project but it doesn't seem to work with my Repository-Pattern project. </p> <p>I have created a MustBeTrue validation, meaning, the method checks to see if a given checkbox is checked (terms and conditions). </p> <pre><code>[Display(Name = "I accept the terms and conditions")] [MustBeTrue(ErrorMessage = "Please accept terms and conditions before public bool AcceptTerms { get; set; } //non-relevant properties follow //....method listed below [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)] public class MustBeTrueAttribute : ValidationAttribute { public override bool IsValid(object value) { return value != null &amp;&amp; value is bool &amp;&amp; (bool)value; } } </code></pre> <p>I have this exact same piece of code in a seperate project, created a view and used this model, validation works perfectly. However, when trying to replicate it in my other project, which uses a repository instead of having the model right in the web application, my custom validation does not run.</p> <p>EDIT: Another very important thing to add is that I have a helper to display the fields particular to that entity, eg, I'm using <code>MvcHtmlString</code> to return a string of the fields that need to be filled out.</p> <p>Are there any settings I must check before giving up on this? Is there anything by "default" that should hook up my custom annotations that I haven't done?</p> <p>NOTE: System.ComponentModel.DataAnnotations work fine in my repository project, it's only custom ones I can't get to work.</p> <p>Thanks for any help! Greatly appreciated.</p>

    1. COSOLVED: Problem lies in using HTML helpers to bring back the data inputs (where the MvcHtmlString was returned). Haven't figured out how to make them work on this scenario

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.

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