= List of Available Converters =
The following list contains all currently available converters for UBIK Xamarin customizing. '''Two-way''' converters can be used with two-way bindings, e.g. a text-box displaying an editable value. If the value updates in the model, the text-box text changes. If the user edits the value, the value in the model behind also gets updated.
