How to Insert Line Break using LabelFor in MVC

Question

I have in my Model:

[Display(Name = "Check to enter <break> the Quantity of items")]
public bool IsLimitedQuantity { get; set; }

and I am using

@Html.LabelFor(shop => shop.IsLimitedQuantity)

in my view.

Please suggest how I can fix this, because the label is just showing <break> as it is, instead of breaking to a new line.

is being rendered as it is...how to give line break...please help !!! — Umesh K., May 07 '12 at 07:46
If this is because the label is display too side, then you should be using CSS to fix this, not HTML. — Rob Cooper, May 07 '12 at 07:55

You could write a custom LabelFor helper which doesn't HTML encode the text as does the standard LabelFor helper:

public static class LabelExtensions
{
    public static IHtmlString UnencodedLabelFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
        var htmlFieldName = ExpressionHelper.GetExpressionText(expression);
        var text = (metadata.DisplayName ?? (metadata.PropertyName ?? htmlFieldName.Split(new char[] { '.' }).Last<string>()));
        if (string.IsNullOrEmpty(text))
        {
            return MvcHtmlString.Empty;
        }
        var tagBuilder = new TagBuilder("label");
        tagBuilder.Attributes.Add("for", TagBuilder.CreateSanitizedId(html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(htmlFieldName)));
        tagBuilder.InnerHtml = text;
        return new HtmlString(tagBuilder.ToString(TagRenderMode.Normal));
    }
}

and then use this custom helper in the view:

@Html.UnencodedLabelFor(x => x.IsLimitedQuantity)

Now the HTML tags in the display name will be rendered without encoding:

[Display(Name = "Check to enter <br/> the Quantity of items")]
public bool IsLimitedQuantity { get; set; }

Totally valid solution (and +1 for it), but allowing DSL/markup in metadata makes me feel barfy. — moribvndvs, May 07 '12 at 07:58
Perfect :) and I were to put it in Resources instead of metadata. — Wahid Bitar, May 07 '12 at 09:54

Using Html decode may help. MVC for security reasons encode all the values.

so you mean something like this? @Server.HtmlDecode(Html.LabelFor(m=>m.Val1).ToHtmlString()) – McGarnagle May 07 '12 at 07:53
even you can try @Darin solution as well – Deepesh May 07 '12 at 07:59
