Introduction

In this blog I have taken on slider, one textbox and one textblock controls. this code example uses value of slider for setting the text of textbox and for increasing the font size value of textblock

to do the above task, I have use the Element Binding

XAML Code

<Window x:Class="Example02.Window1"

Title="Example 01" Height="300" Width="300">
<Grid>
<Grid.RowDefinitions >
<RowDefinition Height="60px" />
<RowDefinition Height="40px" />
<RowDefinition Height="40px" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ComboBox Name="FontNameList" ItemsSource="{Binding Source={x:Static Fonts.SystemFontFamilies}}" Height="22" SelectedIndex="22" Grid.Row="0"/>
<Slider Name="fontSizeSlider" Minimum="5" Maximum="100" Value="10" Grid.Row="1" />
<TextBox Name="SizeTextBox" Text="{Binding ElementName=fontSizeSlider, Path=Value}" Grid.Row="2"/>
<TextBlock Text="Example 01" FontFamily="{Binding ElementName=FontNameList, Path=Text}" FontSize="{Binding ElementName=SizeTextBox, Path=Text}" Grid.Row="3"/>
