Some Controls in depth
Controls make the visual elements of your app.
An app will have one or more forms. Each form will have a collection of controls on it, customized by you with different sizes and appearances.
In this section, we will see how to add controls and forms to an app.
Add controls to your app by dragging and dropping them into place. Then, resize and set the properties.
