# CheckedListBox Control in C#.net

CheckedListBox is a combination of a ListBox and a [CheckBox](https://www.mindstick.com/articles/291/how-should-use-checkbox-control-in-vb-dot-net). CheckedListBox can have items added using the String [Collection](https://www.mindstick.com/articles/1718/collections-in-java) Editor or their items can add dynamically from a collection at run time, using the Items [property](https://www.mindstick.com/articles/198559/an-ownership-of-property-in-hua-hin).\

## How to use CheckedListBox Control

[Drag and drop](https://www.mindstick.com/forum/454/how-to-drag-and-drop-multiple-image-from-one-canvas-to-onther-canvas-in-html5) a CheckedListBox from toolbox on the windowForm.

CheckOnClick property should be true in CheckedListBox so that when you click on the Text then references checkbox is checked.

**Code:**

```
using System;using System.Text;using System.Windows.Forms; namespace WindowsFormsApplication1{     public partial class Form5 : Form    {         public Form5()         {            InitializeComponent();         }         private void Form5_Load(object sender, EventArgs e)         {            // add item in checkedListBox            checkedListBox1.Items.Add("C#");            checkedListBox1.Items.Add("VB");            checkedListBox1.Items.Add("Java");         }         private void checkedListBox1_SelectedIndexChanged(object sender, EventArgs e)         {            // Show selected Item in Label            label1.Text = "Selected Language is  " + checkedListBox1.SelectedItem.ToString();         }    }}
```

In above code Item is added dynamically so all Items in CheckedListBox1 will show at run time.

## Run the [application](https://www.mindstick.com/articles/12824/calculator-application-in-android)

When you select the given option then SelectedIndexChanged event will fire and [selected value](https://www.mindstick.com/forum/525/get-selected-value-of-datagridviewcomboboxcolumn) will show in the Label.
