Converters

Most of the time, when data is shown to the user, there are aspects or values, which are not clear or intuitive enough for them. A way to solve this problem is by changing the format or making a conversion before binding. To do so, Silverlight offers an interface which allows us to perform this action.

Note

If you need to make simple formatting (for example, displaying a Date or Time), StringFormat can be directly used on the XAML (this was introduced in Silverlight 4). For more information, please visit http://bit.ly/jMBtDp.

  • Convert: This function prepares the data, obtained from the DataSource, to display it in the view.

  • ConvertBack: This one is in charge of making the opposite change, it gets the data ready from the view to store in the source.

We will generate an instance to convert the numerical value provided by a property, to an image. The final result will appear similar to the following...
