Confirmation mvc.net supports ValidationGroup concept

Question

Based on the asp.net background, I really appreciated the concept of "validationGroup" when adding validation to the page. I was looking for the appropriate concept in mvc.net and didn't have much luck.

Is this concept available in mvc.net? If not, what are my alternatives?

Answer 1

Unfortunately, no, he has nothing of the kind.

I wrote about a workaround when he returned.

ASP.NET MVC - Validation Summary with 2 Forms and 1 View

The essence of the blog post:

namespace System.Web.Mvc { public static class HtmlExtensions { public static string ActionValidationSummary(this HtmlHelper html, string action) { string currentAction = html.ViewContext.RouteData.Values["action"].ToString(); if (currentAction.ToLower() == action.ToLower()) return html.ValidationSummary(); return string.Empty; } } } 

and

 <h2>Register</h2> <%= Html.ActionValidationSummary("Register") %> <form method="post" id="register-form" action="<%= Html.AttributeEncode(Url.Action("Register")) %>"> ... blah ... </form> <h2>User Login</h2> <%= Html.ActionValidationSummary("LogIn") %> <form method="post" id="login-form" action="<%= Html.AttributeEncode(Url.Action("LogIn")) %>"> ... blah ... </form>

Charlino response extension, including HtmlAttributes and other ValidationSummary properties:

  public static MvcHtmlString ActionValidationSummary(this HtmlHelper html, string action, bool excludePropertyErrors, string message, object htmlAttributes = null) { var currentAction = html.ViewContext.RouteData.Values["action"].ToString(); if (currentAction.ToLower() == action.ToLower()) { return html.ValidationSummary(excludePropertyErrors, message, htmlAttributes); } return new MvcHtmlString(string.Empty); }

Charles's method was the only approach I could find that really worked for my purposes! (T.E. Two forms on the same MVC page → without executing forms inside partial and ajax loads for partial numbers. This did not help me, since I wanted to return different result sets that would be displayed outside the div form, depending on what form was submitted)

I would advise making a small modification to the Html extension because you still want the validation summary to be displayed for an inconsistent check summary so that client-side validation works:

 namespace System.Web.Mvc { public static class HtmlExtensions { public static MvcHtmlString ActionValidationSummary(this HtmlHelper html, string action) { string currentAction = html.ViewContext.RouteData.Values["action"].ToString(); if (currentAction.ToLower() == action.ToLower()) return html.ValidationSummary(); return new MvcHtmlString("<div class=\"validation-summary-valid\" data-valmsg-summary=\"true\"><ul><li style=\"display:none\"></li></ul></div>"); } } }
