Is there a way to allow a user to submit html content while still enabling model validation?

阅读更多关于 Is there a way to allow a user to submit html content while still enabling model validation?

问题 I need to allow users to submit a form value containing html in their text inputs. This is an internally-facing application so it's reasonably safe to do so.

Like so: public class Entry { [Required] public Person Subscriber { get;

问题 I have a registration form on which I use client side validation (Required, StringLength etc. specified on my view model). The form is currently pretty much how the scaffolder creates it: @using (Html.BeginForm("Index", "Registration")) { @Html.ValidationSummary(true) <fieldset> <legend>Registration details</legend> @Html.ValidationSummary(false, "Please correct these errors:") @Html.ValidationMessageFor(model => model.Username) <div class="editor-label"> @Html.LabelFor(model => model
