A Simple Silverlight Data Binding

Published on Monday, August 22, 2011

Data binding in Silverlight is accomplished by using Binding class. There are 2 components in Binding class: the source and the target, and binding mode which indicates the binding way is one way or two way.

MainPage.xaml:

<UserControl x:Class="SLDataBind.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" Loaded="UserControl_Loaded" d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>
        <TextBlock Text="Full Name" VerticalAlignment="Center" Margin="5" Grid.Row="0" />
        <TextBlock Text="Phone Number" VerticalAlignment="Center" Margin="5" Grid.Row="1" />
        <TextBox Text="{Binding FullName}" Height="24" Margin="5" Grid.Column="1" Grid.Row="0" />
        <TextBox Text="{Binding PhoneNo}" Height="24" Margin="5" Grid.Column="1" Grid.Row="1" />
    </Grid>
</UserControl>

MainPage.xaml.cs:

    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void UserControl_Loaded(object sender, RoutedEventArgs e)
        {
            Person p = new Person { FullName = "Jason", PhoneNo = "416-123-4567" };
            this.LayoutRoot.DataContext = p;
        }
    }

    public class Person
    {
        public string FullName
        {
            get;
            set;
        }

        public string PhoneNo
        {
            get;
            set;
        }
    }
