In my previous post, I discussed the three modes of DataBinding for Windows 8. Today we’ll take a brief look at binding not to data, but rather binding one UI element to the value of another. In this example, we’ll bind the IsActive property of the ProgressRing to the IsChecked property’s value in a CheckBox.
<StackPanel>
<StackPanel
Orientation="Horizontal"
HorizontalAlignment="Left"
>
<TextBlock
Text="ProgressRing:"
VerticalAlignment="Center"
Margin="0,0,20,0" />
<Border
BorderThickness="1"
BorderBrush="#44000000"
Padding="10">
<ProgressRing
x:Name="ProgressRing1"
IsActive="{Binding IsChecked,
ElementName=ActiveCB}" />
</Border>
</StackPanel>
<CheckBox
Name="ActiveCB"
Content="Active?" />
</StackPanel>
Notice that the IsActive property is bound to the IsChecked property and the ElementName (ActiveCB) is the Name of the CheckBox with that property.
That’s it, there is no code associated with this example; just the XAML.
