    <p>I have created the following custom RegularExpressionAttribute</p> <pre><code>[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = false)] public class AlphaNumericAttribute: RegularExpressionAttribute, IClientValidatable { public AlphaNumericAttribute() : base("^[-A-Za-z0-9]+$") { } public IEnumerable&lt;ModelClientValidationRule&gt; GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { yield return new ModelClientValidationRule { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "alphanumeric" }; } } </code></pre> <p>The field in the ViewModel is decorated with my AlphaNumeric attribute:</p> <pre><code>[AlphaNumeric(ErrorMessageResourceType = typeof(Resources), ErrorMessageResourceName = Resources.DriverLicenseNumber_RegexError_)] public string DriverLicenseNumber { get; set; } </code></pre> <p>The field is built in the view:</p> <pre><code>@using (Html.BeginForm("Index", "Application", FormMethod.Post, new { id = "applicationDataForm", autocomplete = "off" })) { @Html.LabelFor(m =&gt; m.DriverLicenseNumber) @Html.ValidationMessageFor(m =&gt; m.DriverLicenseNumber) @Html.TextBoxFor(m =&gt; m.DriverLicenseNumber) } </code></pre> <p>This should yield the proper <em>"data-"</em> validation attributes on my html input tag. However, the rendered tag looks like this:</p> <pre><code>&lt;input data-val="true" data-val-alphanumeric="Please enter a valid driver's license number." id="DriverLicenseNumber" name="DriverLicenseNumber" type="text" value="" maxlength="20" class="valid"&gt; </code></pre> <p>Conspicuously absent are the <em>data-val-regex</em> and <em>data-val-regex-pattern</em> attributes that are supposed be rendered. </p> <p>I have built other validators with the exact same structure, and they work correctly, like this SSN validation which handles masked spaces for a masked input using jquery masking:</p> <pre><code>public class SsnAttribute : RegularExpressionAttribute, IClientValidatable { public SsnAttribute() : base("^([0-9]{3}–[0-9]{2}–[0-9]{4})|([ ]{3}–[ ]{2}–[ ]{4})|([0-9]{9,9})$") { } public IEnumerable&lt;ModelClientValidationRule&gt; GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { yield return new ModelClientValidationRule { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "ssn" }; } </code></pre> <p>}</p> <p>With the accompanying application on the ViewModel:</p> <pre><code>[Ssn(ErrorMessageResourceType = typeof(Resources), ErrorMessageResourceName = Resources.SocialSecurity_RegexError_)] public new string SocialSecurityNumber { get; set; } </code></pre> <p>The field is built in the view:</p> <pre><code>@using (Html.BeginForm("Index", "Application", FormMethod.Post, new { id = "applicationDataForm", autocomplete = "off" })) { @Html.LabelFor(m =&gt; m.SocialSecurityNumber) @Html.ValidationMessageFor(m =&gt; m.SocialSecurityNumber) @Html.TextBoxFor(m =&gt; m.SocialSecurityNumber) } </code></pre> <p>This validation attribute correctly renders the data-val-regex and data-val-regex-pattern attributes:</p> <pre><code>&lt;input class="SSNMask valid" data-val="true" data-val-regex="Please enter a valid social security number." data-val-regex-pattern="^([0-9]{3}–[0-9]{2}–[0-9]{4})|([ ]{3}–[ ]{2}–[ ]{4})|([0-9]{9,9})$" id="SocialSecurityNumber" name="SocialSecurityNumber" type="text" value="" maxlength="22"&gt; </code></pre> <p><br/><br/> I cannot figure out what I am missing with the AlphaNumeric attribute that it does not render the appropriate html attributes.</p>

    1. COHow/where in your view you are generating the corresponding input field? Are you using `Html.TextBoxFor`? Or `Html.EditorFor`? Is this call inside an `Html.BeginForm`? Could you please show your view?

    2. CO@Darin. I have updated my question to show the code from the view. I am using TextBoxFor with both the functional SSN validator and the non-functional AlphaNumeric validator

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).
