Remarks

IMPORTANT

Bootstrap Controls for ASP.NET Core are in maintenance mode. We don’t add new controls or develop new functionality for this product line. Our recommendation is to use the ASP.NET Core Controls suite.

$1 Grid View provides you with three main routing types:

• updating the control markup;
• implementing the CRUD (create, update and delete) functionality;
• implementing a custom server-side logic.

The example below demonstrates how to implement a custom server-side logic using the Routes method.

View

@(Html.DevExpress()
    .BootstrapButton("groupByCountryButton")
    .Text("Group by Country column")
    .ClientSideEvents(events => events.Click("onGroupByCountryButtonClick")))

@Html.Partial("GridViewPartial", Model)

View (GridViewPartial)

@model IEnumerable

@(Html.DevExpress()
    .BootstrapGridView<Customer>("gridView")
    .Routes(routes => routes
        .MapRoute(route => route
            .Controller("GridView")
            .Action("GridViewPartial"))
        .MapRoute(route => route
            .RouteType(GridViewRouteType.Custom)
            .Controller("GridView")
            .Action("GroupBy")))
    .Settings(settings => settings.ShowGroupPanel(true))
    .Columns(columns => {
        columns.Add(m => m.ContactName);
        columns.Add(m => m.CompanyName);
        columns.Add(m => m.Country).GroupIndex(1);
        columns.Add(m => m.City);
        columns.Add(m => m.Region);
    })
    .Bind(Model))

Controller

using System;
using DevExpress.AspNetCore.DemoModels;
using Microsoft.AspNetCore.Mvc;

namespace DevExpress.AspNetCore.Demos {
    public class GridViewController : Controller {
        public GridViewController(IDevExpressControlAccessor devExpress, NorthwindContext northwindContext){
            DevExpress = devExpress;
            NorthwindContext = northwindContext;
        }

        protected IDevExpressControlAccessor DevExpress { get; }
        protected NorthwindContext NorthwindContext { get; }

        public IActionResult Index() {
            return View(NorthwindContext.Customers);
        }
        public IActionResult GridViewPartial() {
            return PartialView(NorthwindContext.Customers);
        }
        public IActionResult GroupBy() {
            var grid = DevExpress.GridView("GridViewPartial", NorthwindContext.Customers);
            grid.ClearSort();
            grid.DataColumns["Country"].GroupBy();
            grid.ExpandAll();
            return grid.GetActionResult();
        }
    }
}

Script

function onGroupByCountryButtonClick(args) {
    grid.performCallback();
}
