在ASP.NET Core中使用WebGrid [英] Using WebGrid in ASP.NET Core

问题描述

我在ASP.NET Core应用程序中使用System.Web.Helpers.WebGrid控件， 渲染网格时出现以下错误

I am using System.Web.Helpers.WebGrid control in ASP.NET Core application, I am getting the below error while rendering the grid

An unhandled exception occurred while processing the request.

ArgumentNullException: Value cannot be null.
 Parameter name: httpContext

System.Web.HttpContextWrapper..ctor(HttpContext httpContext)

在线

System.Web.Helpers.WebGrid objWebGrid = new System.Web.Helpers.WebGrid(Model.MeetingsObj);

型号:

public class Meeting
    {

        public int MeetingId { get; set; }
        public string MeetingName { get; set; }
        public string Format { get; set; }
        public string Location { get; set; }
    }

    public class MeetingVM
    {
        public Meeting MeetingObj { get; set; }
        public List<Meeting> MeetingsObj { get; set; }
        public Boolean ShowGridHeader { get; set; }
    }

任何人都可以为上述错误提供解决方案吗?

推荐答案

您可以尝试使用其他组件，我建议使用MVC6网格 http://mvc6-grid.azurewebsites.net/

基本上使用几乎相同的语法，因此您当前的代码将有少量更改，请检查下面的示例代码

basically it use almost same syntax ,so there will be minor changes to your current code ,please check the below sample code

@model IEnumerable<PersonModel>

@(Html
.Grid(Model)
.Build(columns =>
{
    columns.Add(model => model.Name).Titled("Name");
    columns.Add(model => model.Surname).Titled("Surname");

    columns.Add(model => model.Age).Titled("Age");
    columns.Add(model => model.Birthday).Titled("Birth date");
    columns.Add(model => model.IsWorking).Titled("Employed");

//popup part
columns.Add(model => $"<a  data-modal='' data-id=\"{model.Id}\"     href='PasswordRestUser/{model.Id}'      id=\"ss\"  asp-    action=\"PR\" asp-route-id=\"@item.Id\" class=\"btn     btn-info\" '> PR <span class='glyphicon      glyphicon-user'> </span> </a>").Encoded(false);

})
.Filterable()
.Sortable()
.Pageable()
)

<div id='myModal' class='modal fade in'>
    <div class="modal-dialog">
        <div class="modal-content">
            <div id='myModalContent'></div>
        </div>
    </div>
</div>

它还具有许多其他功能，这些功能使.netcore变得更容易
