This Article explains how to create a CheckBoxList and how to get the Text and Value of a checked CheckBoxListItem in WPF.

First create a CheckBoxList using ListBox with DataTemplate as follows in XAML.

<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="CheckBoxLsit" Height="350" Width="525">
<
Grid>
<
StackPanel Width="250" Height="80">
<
ListBox Name="listBoxZone" ItemsSource="{Binding TheList}"
 Height="115" Background="Azure">
<
ListBox.ItemTemplate>
<
DataTemplate>
 <
CheckBox Name="CheckBoxZone" Content="{Binding TheText}
     Tag="{Binding TheValue}" Checked="CheckBoxZone_Checked"  
     Margin
="0,5,0,0"/>
</
DataTemplate
</
ListBox.ItemTemplate>
</
ListBox>
</
StackPanel>
<
TextBox Name="ZoneText" Width="160" Height="20" Margin="-80,140,0,0" Background="Bisque" />
<
TextBox Name="ZoneValue" Width="160" Height="20" Margin="-80,190,0,0" Background="Bisque" />
</
Grid>
</
Window>

Binding data to CheckBoxList in .XAML.Cs

Using System.Collections.ObjectModel;
namespace WpfApplication1
{
/// <summary>
///
Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public ObservableCollection<BoolStringClass> TheList {get; set ;}
public MainWindow()
{
InitializeComponent();
CreateCheckBoxList();
}
public class BoolStringClass
{
       public string TheText { get; set; }
       public int TheValue { get; set; }
}
public void CreateCheckBoxList()
{
TheList =
new ObservableCollection<BoolStringClass>();
TheList.Add(
new BoolStringClass { TheText = "EAST" ,TheValue =1});
TheList.Add(
new BoolStringClass { TheText ="WEST",TheValue =2});
TheList.Add(
new BoolStringClass { TheText ="NORTH", TheValue=3});
TheList.Add(
new BoolStringClass {TheText ="SOUTH", TheValue =4});
this.DataContext =this;
}


Get the Text and value of Checked CheckBoxList

Write the code below in the checkBox Checked Event.

private void CheckBoxZone_Checked(object sender, RoutedEventArgs e)
{
CheckBox chkZone = (CheckBox)sender;
ZoneText.Text =
"Selected Zone Name= "+ chkZone.Content.ToString();
ZoneValue.Text =
"Selected Zone Value= " + chkZone.Tag.ToString();
}
