WPF Simple Data Binding Example

Binding property value from one control to property of another:

In the example below, we will bind value of Text property of first TextBox named textBox1 to the Text property of the last TextBox. 

<Window x:Class="BindingExample.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow" Height="350" Width="525">

    <Grid>

        <TextBox Height="23" HorizontalAlignment="Left" Margin="182,81,0,0" Name="textBox1" VerticalAlignment="Top" Width="239" />

        <TextBlock Height="23" HorizontalAlignment="Left" Margin="88,81,0,0" Name="textBlock1" Text="Enter Something" VerticalAlignment="Top" />

        <TextBox Height="141" HorizontalAlignment="Left" Margin="88,110,0,0" Name="textBox2" VerticalAlignment="Top" Width="333"

              Text="{Binding ElementName=textBox1, Path=Text}"   />

    </Grid>

</Window>
