There's no @Html.Button !

Question

I see references out there for @Html.Button(), but when I type that, IntelliSense doesn't find such a helper... there's dropdownlist, hidden, editors, et cetera, but no button!

Why is that?

Answer 1

public static class HtmlButtonExtension  {    public static MvcHtmlString Button(this HtmlHelper helper,                                       string innerHtml,                                       object htmlAttributes)    {      return Button(helper, innerHtml,                   HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes)     );    }    public static MvcHtmlString Button(this HtmlHelper helper,                                       string innerHtml,                                      IDictionary<string, object> htmlAttributes)   {       var builder = new TagBuilder("button");       builder.InnerHtml = innerHtml;       builder.MergeAttributes(htmlAttributes);       return MvcHtmlString.Create(builder.ToString());   } }

There is no button helper as of mvc preview 3 (not mvc3)

it was mentioned a bunch in the past for example: http://blog.wekeroad.com/blog/aspnet-mvc-preview-using-the-mvc-ui-helpers/ however rolling your own is trivial - I have a basis for it somewhere around here I'll have to dig it up, but essentially just create a new Html.ButtonFor and copy the source code from Html.LabelFor and change the output to create an input type="button" tag.

To expand on the accepted answer, so you can bind a submit button to a model property but have different text:

@Html.ButtonFor(m => m.Action, Model.LabelForCurrentAction(), new { @class = "btn btn-primary btn-large", type = "submit" })

Using the following slightly modified Button helper class:

/// <summary>
/// Via https://stackoverflow.com/questions/5955571/theres-no-html-button
/// </summary>
public static class HtmlButtonExtension
{

    public static MvcHtmlString Button(this HtmlHelper helper, object innerHtml, object htmlAttributes)
    {
        return helper.Button(innerHtml, HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes));
    }

    public static MvcHtmlString Button(this HtmlHelper helper, object innerHtml, IDictionary<string, object> htmlAttributes)
    {
        var builder = new TagBuilder("button") { InnerHtml = innerHtml.ToString() };
        builder.MergeAttributes(htmlAttributes);
        return MvcHtmlString.Create(builder.ToString());
    }

    public static MvcHtmlString ButtonFor<TModel, TField>(this HtmlHelper<TModel> html,
                                                        Expression<Func<TModel, TField>> property,
                                                        object innerHtml,
                                                        object htmlAttributes)
    {
        // lazily based on TextAreaFor

        var attrs = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);

        var name = ExpressionHelper.GetExpressionText(property);
        var metadata = ModelMetadata.FromLambdaExpression(property, html.ViewData);

        string fullName = html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name);

        ModelState modelState;
        if (html.ViewData.ModelState.TryGetValue(fullName, out modelState) && modelState.Errors.Count > 0)
        {
            if( !attrs.ContainsKey("class") ) attrs["class"] = string.Empty;
            attrs["class"] += " " + HtmlHelper.ValidationInputCssClassName;
            attrs["class"] = attrs["class"].ToString().Trim();
        }
        var validation = html.GetUnobtrusiveValidationAttributes(name, metadata);
        if(null != validation) foreach(var v in validation) attrs.Add(v.Key, v.Value);

        string value;
        if (modelState != null && modelState.Value != null)
        {
            value = modelState.Value.AttemptedValue;
        }
        else if (metadata.Model != null)
        {
            value = metadata.Model.ToString();
        }
        else
        {
            value = String.Empty;
        }

        attrs["name"] = name;
        attrs["Value"] = value;
        return html.Button(innerHtml, attrs);
    }
}

Answer 4

MVC5 , Bootstrap ver 3.2.0

@Html.ActionLink
(
    linkText: " Remove", 
    actionName: "Index", 
    routeValues: null, // or to pass some value -> routeValues: new { id = 1 },
    htmlAttributes: new { @class = "btn btn-success btn-sm glyphicon glyphicon-remove" }
)

This will generate a link that looks like a button.
