为TextBoxFor扩展Kendo HtmlHelpers
我正在寻找如何扩展Kendo HtmlHelpers来做类似的事情
@Html.Kendo().TextBoxFor(model => model.field)
这是我的建议
using System;
using System.Collections.Generic;
using System.Diagnostics.CodeAnalysis;
using System.Linq.Expressions;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using Kendo.Mvc.UI.Fluent;
namespace Kendo.Mvc.UI
{
public static class KendoExtensions
{
[SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures", Justification = "This is an appropriate nesting of generic types")]
public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression)
{
return htmlHelper.TextBoxFor(expression, format: null);
}
[SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures", Justification = "This is an appropriate nesting of generic types")]
public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, string format)
{
return htmlHelper.TextBoxFor(expression, format, null);
}
[SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures", Justification = "This is an appropriate nesting of generic types")]
public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
{
return htmlHelper.TextBoxFor(expression, null, htmlAttributes);
}
[SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures", Justification = "This is an appropriate nesting of generic types")]
public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, string format, object htmlAttributes)

}

public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, IDictionary<string, object> htmlAttributes)
{

}
[SuppressMessage("Microsoft.Design", "CA1006:DoNotNestGenericTypesInMemberSignatures", Justification = "This is an appropriate nesting of generic types")]
public static MvcHtmlString TextBoxFor<TModel, TProperty>(this WidgetFactory<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, string format, IDictionary<string, object> htmlAttributes)
{
var lKWidget = new TagBuilder("span");
lKWidget.AddCssClass("k-widget k-numerictextbox");
var lKExpanding = new TagBuilder("span");
lKExpanding.AddCssClass("k-numeric-wrap k-expand-padding k-state-disabled");
if (htmlAttributes == null) htmlAttributes = new Dictionary<string, object>();
if (htmlAttributes.ContainsKey("class"))
{
htmlAttributes["class"] += "k-formatted-value k-input";
} else
{
htmlAttributes.Add("class", "k-formatted-value k-input");
}
var lTextBoxFor = htmlHelper.HtmlHelper.TextBoxFor(expression, format, htmlAttributes).ToHtmlString();
lKExpanding.InnerHtml += lTextBoxFor;
lKWidget.InnerHtml += lKExpanding;
lKWidget.InnerHtml += htmlHelper.HtmlHelper.ValidationMessageFor(expression);
return MvcHtmlString.Create(lKWidget.ToString(TagRenderMode.Normal));
}
}
}
Kendo UI的新版本（2014.2.716）有这个扩展，还有更多......
