If you want the full control, you can use the Explicit value and then do the updates manually, but this does take a bit of the fun out of working with data bindings.
So far, we worked with styles by setting a static value for a specific property.
However, using triggers, you can change the value of a given property, once a certain condition changes.
Triggers come in multiple flavors: Property triggers, event triggers and data triggers.
Data triggers, represented by the element, are used for properties that are not necessarily dependency properties.We then supply a default style, where the text is "No" and the foreground color is red, and then, using a Data Trigger, we supply a style for when the Is Checked property of the Check Box is changed to True, in which case we make it green with a text saying "Yes! element, are mostly used to trigger an animation, in response to an event being called.We haven't discussed animations yet, but to demonstrate how an event trigger works, we'll use them anyway.The second Text Box uses the Lost Focus value, which is actually the default for a Text binding.It means that the source value will be updated each time the destination control loses focus.
