Hi,
I have implemented a custom IComand class for one of my buttons. The
button is placed in a page 'MyPage.xaml' but its custom ICommand class is placed in another class, not in the MyPage code behind. Then from XAML I want to bind the
button with its custom command class and then I do:
MyPage.xaml:
<Page ...>
<Page.CommandBindings>
<CommandBinding Command="RemoveAllCommand"
CanExecute="CanExecute"
Executed="Execute" />
</Page.CommandBindings>
<Page.InputBindings>
<MouseBinding Command="RemoveAllCommand" MouseAction="LeftClick" />
</Page.InputBindings>
<...>
<Button x:Name="MyButton" Command="RemoveAllCommand" .../>
<...>
</Page>
and the custom command
button class:
// Here I derive from MyPage class because I want to access some objects from
// Execute method
public class RemoveAllCommand : MyPage, ICommand
{
public void Execute(Object parameter)
{
<...>
}
public bool CanExecute(Object parameter)
{
<...>
}
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
}
My problem is how to say MyPage.xaml that Execute and CanExecute methods for the
button is in another class and not the code behind where is placed the
button. How to say these methods are in RemoveAllCommand Class in XAML page.
Also I want to fire this command when click mouse event is produced in the
button so I do an input binding, is it correct?
Thanks
