Hi Ankita,\
You can use the following code:

```
using System;using System.Drawing;using System.Windows.Forms;namespace WindowsFormsApplication1{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void Form1_Load(object sender, EventArgs e)        {            checkedListBox1.Items.Add("Sunday", CheckState.Checked);            checkedListBox1.Items.Add("Monday", CheckState.Unchecked);            checkedListBox1.Items.Add("Tuesday", CheckState.Indeterminate);            checkedListBox1.Items.Add("Wednesday", CheckState.Checked);            checkedListBox1.Items.Add("Thursday", CheckState.Unchecked);            checkedListBox1.Items.Add("Friday", CheckState.Indeterminate);            checkedListBox1.Items.Add("Saturday", CheckState.Indeterminate);        }    }}
```
