网格.在控制器中使用过滤的结果

本文关键字:过滤 结果 控制器 网格 | 更新日期: 2023-09-27 18:04:32

我使用grid.mvc(http://gridmvc.codeplex.com/)进行过滤和排序。有人知道如何在动作控制器中处理过滤的结果吗。我试图通过FormCollection传递一个隐藏的字段,但由于只传递了可见的值。或者在mvc中有任何好的替代网格,在那里你可以过滤和排序,并使用过滤的结果在和mvc控制器中的动作?

_customersGrid.cshtml

    @using GridMvc.Html
@using GridMvc.Site.Models
@using GridMvc.Sorting
@model GridMvc.Site.Models.Grids.CustomersGrid
@{
    ViewBag.Title = "_CustomersGrid";
}
<h2>_PersonsGrid</h2>
@Html.Grid(Model).Named("customersGrid").Columns(columns =>
    {
        columns.Add(o => o.CustomerID)
            .Encoded(false)
        .Sanitized(false)
        .SetWidth(30)
             .RenderValueAs(o => Html.Hidden("CustomerID", o.CustomerID));
        columns.Add(o => o.CompanyName)
                .Titled("Name")
                .SetWidth(110);
        columns.Add(o => o.Phone)
               .Titled("Phone")
               .SetWidth(250);

    }).WithPaging(15).Sortable().Filterable().WithMultipleFilters()

Index.cshtml

@{
    ViewBag.Title = "Home";
}
    @using (Html.BeginForm(null, null, FormMethod.Post, new { @class = "form-horizontal" }))
{   
<fieldset>
<legend></legend>
        @Html.Action("Grid") @* grid in a partial view *@
          <p>
             @Html.ActionLink("Back", "Index",null,new { @class = "btn", @accesskey="b" }) 
       <button type="submit"  class="btn btn-primary" accesskey="s" ><u>S</u>ave</button>
        </p>

    </fieldset>
}
<<p> HomeController行动/strong>
 public ActionResult Index()
        {

            return View();
        }
        [HttpPost]
        public ActionResult Index(  FormCollection form)
        {
            var filterSettings = Session["grid-filters"] as IGridFilterSettings;
            var url = new UriBuilder(Url.Action(null, null, null, Request.Url.Scheme));
            if (filterSettings != null)
                url.Query = GetGridFilterQueryString(filterSettings); //restore grid filter settings

            /* How to get the filtered values from grid insteat from formcollection*/
           var chckedValues = form.GetValues("CustomerId");
            foreach (var id in chckedValues)
            {
                //Do something
                Debug.WriteLine(id);
            };

            ViewBag.ActiveMenuTitle = "Demo";
            return Redirect(url.ToString());
        }
        public ActionResult Grid()
        {
            var repository = new CustomersRepository();
            var grid = new CustomersGrid(repository.GetAll());

            Session["grid-filters"] = grid.Settings.FilterSettings;//store grid filters in the session
            return PartialView("_CustomersGrid", grid);
        }

网格.在控制器中使用过滤的结果

我终于找到了只向控制器发送过滤结果的方法。解决方案是将选择保存到"Shared/_Grid"上的会话。

@helper RenderGridBody()
{
if (!Model.ItemsToDisplay.Any())
{
<tr class="grid-empty-text">
    <td colspan="@Model.Columns.Count()">
        @Model.EmptyGridText
    </td>
</tr>
}
else
{
    Session["Items"]=Model.ItemsToDisplay;
    foreach (object item in Model.ItemsToDisplay)
    {
<tr class="grid-row @Model.GetRowCssClasses(item)">
    @foreach (IGridColumn column in Model.Columns)
    {
        @column.CellRenderer.Render(column, column.GetCell(item))
    }
</tr>
    }
}
} 

当网格。MVC中填充了数据,选择被保存到会话中,以后在控制器中执行动作时可以使用。

在控制器中,您只需要调用并将变量强制转换为正确的类型:

public ActionResult MyController()
    {
        var SelectedRows = (List<ModelType>)Session["Items"];
        List<ModelType> listStats = SelectedRows;
        // the rest of the controller code
}

我希望这对你有帮助。
