How can I bind another DependencyProperty to the IsChecked Property of a CheckBox?
- by speedmetal
Here's an example of what I'm trying to accomplish:
<Window x:Class="CheckBoxBinding.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">
<StackPanel>
<CheckBox Name="myCheckBox">this</CheckBox>
<Grid>
<Grid.Resources>
<Style TargetType="ListBox">
<Style.Triggers>
<Trigger Property="{Binding ElementName=myCheckBox, Path=IsChecked}" Value="True">
<Setter Property="Background" Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
</Grid.Resources>
<ListBox>
<ListBoxItem>item</ListBoxItem>
<ListBoxItem>another</ListBoxItem>
</ListBox>
</Grid>
</StackPanel>
</Window>
When I try to run it, I get this XamlParseException:
A 'Binding' cannot be set on the 'Property' property of type 'Trigger'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject.
So how can I bind a property on the ListBox to the IsChecked property of a CheckBox?
