When you are creating models, there are common scenarios that occur. You can create bits of models, called "patterns" to use in these scenarios. You can then re-use the model patterns whenever the scenario occurs. Patterns can be:
controls
groups of controls
portions of models.
A pattern is any solution that is useful and reusable, from very simple methods to more sophisticated model-fragments.
This topic contains pattern suggestions for some common modelling scenarios.
