ExtJs 4 Grid filter in asp.net mvc action表格 查询与过滤的最佳解析解决方案

 public class ExtFilterInfo
    {
        public string Field { get; set; }
        public ExtFilterData Data { get; set; }
    }

    public class ExtFilterData
    {
        public string Type { get; set; }
        public string Value { get; set; }
        public string Comparison{ get; set; }
    }Action中方法
  public ActionResult OrderData(int start, int limit, string sort, ExtFilterInfo[] filter)
        {
            return View();
        }



模型数据绑定解析

 public class ExtFilterInfoModelBinder : DefaultModelBinder
    {
        public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
        {
            var filter = (ExtFilterInfo)base.BindModel(controllerContext, bindingContext);

            var field = bindingContext.ValueProvider.GetValue(bindingContext.ModelName + "[field]");
            if (field != null)
            {
                filter.Field = field.AttemptedValue;
            }
            var type = bindingContext.ValueProvider.GetValue(bindingContext.ModelName + "[data][type]");
            var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName + "[data][value]");
            var comparison = bindingContext.ValueProvider.GetValue(bindingContext.ModelName + "[data][comparison]");
            if (filter.Data == null)
            {
                filter.Data = new ExtFilterData();
            }
            if (type != null)
            {
                filter.Data.Type = type.AttemptedValue;
            }
            if (value != null)
            {
                filter.Data.Value = value.AttemptedValue;
            }
            if (comparison != null)
            {
                filter.Data.Comparison = comparison.AttemptedValue;
            }
            return filter;
        }
    }注册registered in Application_Start方法中protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RegisterRoutes(RouteTable.Routes);
            ModelBinders.Binders.Add(typeof(ExtFilterInfo), new ExtFilterInfoModelBinder());
        }
一切OK!!!
