How to Bind Data from DataBase to Pie Chart control in Windows using C#.Net

To implement this concept you need to follow the below steps : 

Step1 :
First you need to design a table in Sql Database to retrieve the records from database.

Step2:
On the File menu, click New Project. Select Windows Forms Application as your project type.
Design the Form using controls from Toolbox.

Step3:
Now open the Form.cs page and write the following source code.

Form.CS Code :

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Collections;

namespace Pie_Charts_Sample

{

    public partial class Form1 : Form

    {

        SqlHelper sql = new SqlHelper();

        public Form1()

        {

            InitializeComponent();

            ShowPieChart();

         

        }

        private void ShowPieChart()

        {

            Hashtable ht = new Hashtable();

            DataSet ds = sql.ExecuteProcudere("Student_Marks ", ht);

            DataTable dt = ds.Tables[0];

            PieChart.DataSource = dt;

            PieChart.Series["Series1"].XValueMember = "Name";

            PieChart.Series["Series1"].YValueMembers = "Percentage";

            PieChart.DataBind();

        }

    }

}

Step4:
Now build the Solution and Debug it for the output.
