DXCommand
The DXCommand allows you to bind a command property with methods and functions.
<Button Content="OK" Command="{DXCommand Execute='Save(); Close()', CanExecute='CanSave() and CanClose()'}"/>
The Execute and CanExecute expressions are specified with a special language that is described in the following topic: Language Specification.
You can pass any parameters to calling methods and functions.
<TextBlock x:Name="tb" Text="text"/>
<Button Content="OK" Command="{DXCommand Execute='Save(@e(tb).Text)', CanExecute='CanSave(@e(tb).Text)'}"/>
To access the CommandParameter value, use the @parameter reserved word.
<TextBlock x:Name="tb" Text="text"/>
<Button Content="OK" Command="{DXCommand Execute='Save(@parameter)', CanExecute='CanSave(@parameter)'}" CommandParameter="{DXBinding @e(tb).Text}"/>
The DXCommand extension supports the “=“ operator.
<Button Command="{DXCommand '@e(checkBox).IsChecked=true'}"/>
