Wpf-conditional Binding with Trigger

/* by Dylan sun*/

WPF conditional binding enables the application to has different behaviors based on a pre-defined condition.

For example, you could use conditional binding to change the background color of your WPF application main window.

Suppose you has the following window declaration in your WPF application.

<Window x:class="MainWindow"        xmlns="Http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="Http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:views="Clr-namespace:views"        Xmlns:viewmodels="Clr-namespace:viewmodels"        Xmlns:controls="Clr-namespace:controls"        Title="Main Application"        Height=" the"        Width="1024x768"        DataContext="{Binding Main, Source={staticresource Locator}}">

You could add the following line in the window declaration:

Style="{DynamicResource ResourceKey=MainWindowStyle}"

and use the trigger to change the background color based on the Binded property ' s (environmentisselected) value.

<StyleTargettype="{x:type window}"x:key="Mainwindowstyle"><Style. Triggers><datatrigger binding="{Binding path=environmentisselected}" Value="False"><Setter  Property="Background" Value="Pink"/></datatrigger><datatrigger binding="{Binding path=environmentisselected}" Value="True"><Setter  Property="Background" Value="{Binding selectedenvironment.color}"/></datatrigger></Style. triggers></Style>
