    Create an MVC Application

    Create a new MVC application using the ComponentOne or VisualStudio templates. For more information about creating an MVC application, see Configuring your MVC Application topic.

    Create a Data Source for FlexPie

    1. Add a new class to the folder Models (for example: FlexPieDataSource.cs). See Adding controls to know how to add a new model.
    2. Add the following code to the new model to define the classes that serve as a datasource for the FlexPie control.
      C#
      Copy Code 
      public class FlexPieDataSource
 {
   public string Country { get; set; }
   public int Sales { get; set; }

 public static IEnumerable<FlexPieDataSource> GetData()
  {
    var countries = new[] { "US", "UK",   "China", "France", "German", "Italy" };
    var rand = new Random(0);
    List<FlexPieDataSource> list = new List<FlexPieDataSource>();
     for (int i = 0; i < 6; i++)
      {
        var sales = rand.Next(1, 5);
        list.Add(new FlexPieDataSource {  Sales = sales, Country = countries[i] });
            }
            return list;
        }
    }
      VB
      Copy Code 
      Public Class FlexPieDataSource
    Public Property Country() As String
        Get
            Return m_Country
        End Get
        Set
            m_Country = Value
        End Set
    End Property
    Private m_Country As String
    Public Property Sales() As Integer
        Get
            Return m_Sales
        End Get
        Set
            m_Sales = Value
        End Set
    End Property
    Private m_Sales As Integer

    Public Shared Function GetData() As IEnumerable(Of FlexPieDataSource)
        Dim countries = New String() {"US", "UK", "China", "France", "German", "Italy"}
        Dim rand = New Random(0)
        Dim list As New List(Of FlexPieDataSource)()
        For i As Integer = 0 To 5
            Dim sales = rand.[Next](1, 5)
            list.Add(New FlexPieDataSource() With {
                Key.Sales = sales,
                Key.Country = countries(i)
            })
        Next
        Return list
    End Function
End Class

    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:

      2. Set name of the controller (for example: Default1Controller).
      3. Click Add.
    4. Include the MVC references as shown below.
      C#
      Copy Code 
      using C1.Web.Mvc;
using C1.Web.Mvc.Serializition;
using C1.Web.Mvc.Chart;
    5. Replace the method Index() with the following method.
      C#
      Copy Code 
      public ActionResult QuickStart()
{
    return View(FlexPieDataSource.GetData());
}
      VB
      Copy Code 
      Public Function QuickStart() As ActionResult
Return View(FlexPieDataSource.GetData())
End Function

    Add a View for the Controller

    1. From the Solution Explorer, expand the folder Controllers and double click the controller QuickStartController to open it.
    2. Place the cursor inside the method QuickStart().
    3. Right click and select Add View. The Add View dialog appears.
    4. In the Add View dialog, verify that the view name is QuickStart and View engine is Razor (CSHTML).
    5. Click Add. A view is added for the controller.
    6. Instantiate a FlexPie control in the view QuickStart as shown below.
      Index.cshtml
      Copy Code 
      @using MvcApplication1.Models
@model IEnumerable<FlexPieDataSource>
@(Html.C1().FlexPie<FlexPieDataSource>()
.Bind("Country", "Sales", Model)
)
      Index.vbhtml
      Copy Code 
      @ModelType IEnumerable(Of FlexPieDataSource)

@(Html.C1().FlexPie(Of FlexPieDataSource) _
.Bind("Country", "Sales", Model) _
.Height("300px"))
