Get selected row column values in AngularJS-UI-Grid in MVC

If you want to know how to get started with UI-Grid and how to set up a project in AngularJS and Web API, read the articles given below first.

• UI-Grid With AngularJS And WebAPI
• Export Data In Angular-UI-Grid Using WebAPI
• Filtering In UI-Grid With AngularJS And WebAPI
• Custom Scroll In AngularJS-UI-Grid With Web API
• Expandable grid in AngularJS-UI-Grid with Web API

Angular-UI-Grid has selection row changed feature which gives you all column value from selected row.

Again in this sample I am using NORTHWND sample database and Employee table data.

Entity Model

Web API

Here, my Web API class code is given below.

using ng_ui_grid_sample.Models;
using System.Collections.Generic;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.Description;
namespace ng_ui_grid_sample.Controllers
{
[RoutePrefix("api/employeeapi")]
public class EmployeesAPIController : ApiController
{
private NORTHWNDEntities3 db = new NORTHWNDEntities3();
// GET: api/Employees
[Route("get")]
public IQueryable<Employee> GetEmployees()
{
return db.Employees;
}
// GET: api/Employees/5
[Route("detail")]
[ResponseType(typeof(Employee))]
public async Task<IHttpActionResult> GetEmployees(int id)
{
Employee employees = await db.Employees.FindAsync(id);
if (employees == null)
{
return NotFound();
}
return Ok(employees);
}
// PUT: api/Employees/5
[ResponseType(typeof(void))]
public async Task<IHttpActionResult> PutEmployees(int id, Employee employees)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
if (id != employees.EmployeeID)
{
return BadRequest();
}
db.Entry(employees).State = EntityState.Modified;
try
{
await db.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
if (!EmployeesExists(id))
{
return NotFound();
}
else
{
throw;
}
}
return StatusCode(HttpStatusCode.NoContent);
}
// POST: api/Employees
[ResponseType(typeof(Employee))]
public async Task<IHttpActionResult> PostEmployees(Employee employees)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
db.Employees.Add(employees);
await db.SaveChangesAsync();
return CreatedAtRoute("DefaultApi", new { id = employees.EmployeeID }, employees);
}
// DELETE: api/Employees/5
[ResponseType(typeof(Employee))]
public async Task<IHttpActionResult> DeleteEmployees(int id)
{
Employee employees = await db.Employees.FindAsync(id);
if (employees == null)
{
return NotFound();
}
db.Employees.Remove(employees);
await db.SaveChangesAsync();
return Ok(employees);
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
private bool EmployeesExists(int id)
{
return db.Employees.Count(e => e.EmployeeID == id) > 0;
}
[Route("getterritoriesbyid")]
public IEnumerable<EmployeeTerritory> GetEmployeeTerritoriesByEmployee(int id)
{
return (from et in db.EmployeeTerritories.AsEnumerable()
join t in db.Territories.AsEnumerable() on et.TerritoryID equals t.TerritoryID
where et.EmployeeID == id
orderby et.TerritoryID
select new EmployeeTerritory
{
EmployeeID = et.EmployeeID,
TerritoryID = et.TerritoryID,
TerritoryDescription = t.TerritoryDescription
});
}
}
}

 

Module

//Module
var employeeapp = angular.module('employeeapp', ['ui.grid', 'ui.grid.pagination',
'ui.grid.selection', 'ui.grid.exporter',
'ui.grid.grouping', 'ui.grid.expandable']);

 

Service

//Service
employeeapp.service("employeeservice", function ($http, $timeout) {
//Function to call get employee web api call
this.GetEmployee = function () {
var req = $http.get('api/employeeapi/get');
return req;
}
//function to get territories based on employeeid
this.GetTerritories = function (employeeId) {
var req = $http.get('api/employeeapi/getterritoriesbyid?id=' + employeeId);
return req;
}
});

Controller

//Controller
employeeapp.controller("empcontroller", function ($scope, employeeservice, $filter, $window, $interval, uiGridGroupingConstants, $timeout) {
GetEmployee();
function GetEmployee() {
employeeservice.GetEmployee().then(function (result) {
$scope.Employees = result.data;
console.log($scope.Employees);
}, function (error) {
$window.alert('Oops! Something went wrong while fetching employee data.');
})
}
//Columns
$scope.columnDefs = [
{ name: '', field: 'EmployeeID', enableColumnMenu: false },
{ name: 'photo', enableSorting: false, field: 'PhotoPath', cellTemplate: "<img width=\"50px\" ng-src=\"{{grid.getCellValue(row, col)}}\" lazy-src>", enableCellEdit: false, enableFiltering: false, enableGrouping:false },
{ name: 'First Name', field: 'FirstName', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: true, enableGrouping:false },
{ name: 'Last Name', field: 'LastName', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: true, enableGrouping:false },
{ name: 'Title', field: 'Title', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: false, enableGrouping:false },
{ name: 'City', field: 'City', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: true, enableGrouping:false },
{ name: 'Country', field: 'Country', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: true, enableGrouping:false },
{ name: 'Notes', field: 'Notes', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: false, enableGrouping:false },
{ name: 'Salary', field: 'Salary', headerCellClass: 'tablesorter-header-inner', enableCellEdit: true, enableFiltering: false, enableGrouping:true }
];
//Used to bind ui-grid
//$scope.selectedItem = null;
$scope.gridOptions = {
//For inline filter
enableGridMenu: false,
enableRowSelection: true,
enableRowHeaderSelection: false,
paginationPageSizes: [5, 10, 20, 30, 40],
paginationPageSize: 10,
enableSorting: true,
exporterMenuPdf: false,
enableFiltering: false,
treeRowHeaderAlwaysVisible: false,
multiSelect: false,
onRegisterApi: function (gridApi) {
$scope.gridApi = gridApi;
$scope.name = undefined;
$scope.title = undefined;
$scope.city = undefined;
$scope.country = undefined;
$scope.notes = undefined;
$scope.salary = undefined;
gridApi.selection.on.rowSelectionChanged($scope,function(row){
var msg = 'row selected ' + row.isSelected;
$scope.name = row.entity.FirstName +' '+ row.entity.LastName;
$scope.title = row.entity.Title;
$scope.city = row.entity.City;
$scope.country = row.entity.Country;
$scope.notes = row.entity.Notes;
$scope.salary = row.entity.Salary;
});
},
//end here
columnDefs: $scope.columnDefs,
//data for grid
data: 'Employees'
};
});

As you can see in my controller code I have defined few variables which are having values on row selection changed event. We will bind these values to some html labels next. But before that let’s give references of module, services and controllers.

Global

Now, add a few lines in Global.asax in Application_Start event.

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);

Now, add the mandatory packages given below, using NuGet Package Manager.

Bundling

Bundle the required styles and scripts.

Add the bundles given below in BundleConfig.cs

bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css",
"~/Content/ui-grid.css"));
bundles.Add(new ScriptBundle("~/bundles/uigrid").Include(
"~/Scripts/ui-grid.min.js"));
bundles.Add(new ScriptBundle("~/bundles/angular").Include(
"~/Scripts/angular.min.js",
"~/Angular/Controller/employeecontroller.js",
"~/Angular/Controller/employeegroupingcontroller.js",
"~/Angular/Controller/empcontroller.js"));

Render all the scripts and styles in _Loyout.cshtml

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
@Scripts.Render("~/bundles/angular")
@Scripts.Render("~/bundles/uigrid")
@RenderSection("scripts", required: false)

View

@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>UI-Grid Selected Row Sample</h2>
<div ng-app="employeeapp" ng-controller="empcontroller">
<div ui-grid="gridOptions"
class="grid"
ui-grid-pagination
ui-grid-selection
ui-grid-auto-resize
ng-cloak>
</div>
<div><br /></div>
<div>
Name: <b><label>{{name}}</label></b>
</div>
<div>
Title: <b><label>{{title}}</label></b>
</div>
<div>
City: <b><label>{{city}}</label></b>
</div>
<div>
Country: <b><label>{{country}}</label></b>
</div>
<div>
Notes: <b><label>{{notes}}</label></b>
</div>
<div>
Salary: <b><label>{{salary}}</label></b>
</div>
</div>

That’s it. We are all done here with all now time to run the application.

Output

Now click on any row.

As you can see in screenshot 4, all values from selected row is displaying in labels. You can select any row.

Conclusion
