    In This Topic

    This topic describes how to add a FlexGrid control to your MVC application and populate data in it. The below example demonstrates local model binding in FlexGrid control. Refer to Remote Data Binding for detailed explanation on how to do remote binding in FlexGrid.

    To accomplish this, follow these steps:

    Create a Datasource for FlexGrid

    1. Add a new class to the folder Models (for example: Sale.cs). See Adding controls to know how to add a new model.
    2. Replace the following code in the new model to define the classes that serve as a datasource for the FlexGrid control.
      Sale.cs
      Copy Code
          public class Sale
          {        
              public int ID { get; set; }
              public DateTime Start { get; set; }
              public DateTime End { get; set; }
              public string Country { get; set; }
              public string Product { get; set; }
              public string Color { get; set; }
              public double Amount { get; set; }
              public double Amount2 { get; set; }
              public double Discount { get; set; }
              public bool Active { get; set; }
      
              public MonthData[] Trends { get; set; }
              public int Rank { get; set; }
      
              /// <summary>
              /// Get the data.
              /// </summary>
              /// <param name="total"></param>
              /// <returns></returns>
              public static IEnumerable<Sale> GetData(int total)
              {
                  var countries = new[] { "US", "UK", "Canada", "Japan", "China", "France", "German", "Italy", "Korea", "Australia" };
                  var products = new[] { "Widget", "Gadget", "Doohickey" };
                  var colors = new[] { "Black", "White", "Red", "Green", "Blue" };
                  var rand = new Random(0);
                  var dt = DateTime.Now;
                  var list = Enumerable.Range(0, total).Select(i =>
                  {
                      var country = countries[rand.Next(0, countries.Length - 1)];
                      var product = products[rand.Next(0, products.Length - 1)];
                      var color = colors[rand.Next(0, colors.Length - 1)];
                      var date = new DateTime(dt.Year, i % 12 + 1, 25, i % 24, i % 60, i % 60);
      
                      return new Sale
                      {
                          ID = i + 1,
                          Start = date,
                          End = date,
                          Country = country,
                          Product = product,
                          Color = color,
                          Amount = rand.NextDouble() * 10000 - 5000,
                          Amount2 = rand.NextDouble() * 10000 - 5000,
                          Discount = rand.NextDouble() / 4,
                          Active = (i % 4 == 0),
                          Trends = Enumerable.Range(0, 12).Select(x => new MonthData { Month = x + 1, Data = rand.Next(0, 100) }).ToArray(),
                          Rank = rand.Next(1, 6)
                      };
                  });
                  return list;
              }
          }
      
          public class MonthData
          {
              public int Month { get; set; }
              public double Data { get; set; }
          }
      }

    Add a FlexGrid control

    Complete the following steps to initialize a FlexGrid control.

    Add a new Controller

    1. In the Solution Explorer, right click the folder Controllers.
    2. From the context menu, select Add | Controller. The Add Scaffold dialog appears.
    3. Complete the following steps in the Add Scaffold dialog:
      1. Select Empty MVC Controller template.
      2. Set name of the controller (for example: Default1Controller).
      3. Click Add.
    4. Include the MVC references as shown below.
      C#
      Copy Code
      using System.Collections;
      using System.Globalization;
      using System.Linq;
      using System.Web.Mvc;
      using C1.Web.Mvc;
      using MVCFlexGrid.Models;
      using System.Collections.Generic;
      using System;
      

      Note: Replace MVCFlexGrid.Models; with <YourMVCApplicationName>.Models; in the references.
    5. Replace the method Index() with the following method.

      IndexController.cs

      C#
      Copy Code
      public ActionResult Index()
      {
          return View(Sale.GetData(15));
      }
      

    Add a View for the controller:

    1. From the Solution Explorer, expand the folder Controllers and double click the controller (for example: Default1Controller) to open it.
    2. Place the cursor inside the method Index().
    3. Right click and select Add View. The Add View dialog appears.
    4. In the Add View dialog, verify that the View name is Index and View engine is Razor (CSHTML).
    5. Click Add. A view has been added for the controller.
    6. In the Solution Explorer, double click Index.cshtml to open it.
    7. Replace the default code of the Views\Index.cshtml file with the one given below to initialize a FlexGrid control.
      Razor (Index.cshtml)
      Copy Code
      @using FlexGrid_QS.Models
      @using C1.Web.Mvc.Grid
      @model IEnumerable<Sale>
      
      <style type="text/css">
          .grid {
              height: 500px;
              border: 2px solid #e0e0e0;
              font-family: Cambria;
              font-weight: bold;
          }
      </style>
      
      @*Instantiate FlexGrid and set its properties*@
      @(Html.C1().FlexGrid<Sale>()
                          .AutoGenerateColumns(false)
                          .Width(700)
                          .AllowAddNew(true)
                          .SelectionMode(C1.Web.Mvc.Grid.SelectionMode.Cell)
                          .CssClass("grid")
                          .Bind(Model)
      
                           //Binding columns data to FlexGrid
                           .Columns(bl =>
                           {
                               bl.Add(cb => cb.Binding("ID"));
                               bl.Add(cb => cb.Binding("Start"));
                               bl.Add(cb => cb.Binding("Product"));
                               bl.Add(cb => cb.Binding("Amount").Format("c"));
                               bl.Add(cb => cb.Binding("Discount").Format("p0"));
                               bl.Add(cb => cb.Binding("Active"));
                           }))
