WPF: beginner question ... remember values in textbox

Hi,

With c# V2 in windows apps, I used to bind textboxes in configuration
screens to a settings in the app configuration file using the property grid
and its databindings category. I also save the settings each time the focus
leave the textbox. The idea was to remember the latest values in the
textbox.

Is there any easy way to do the same using WPF ?

Thanks in advance,
Steve

Hi,

You could bind your TextBox's Text property to a .NET object's
property. This property's get and set accessors would in turn deal
with your AppSettings.

Something like:

<TextBox DataContext=myConfigurationObject Text="{Binding
Path=MyProperty}"/>
(Actually, I'd set DataContext higher up so that multiple TextBoxes
can use it without explicitely specifying DataContext over and over
again)
