WPF controls can be categorized in to four categories:-

• Control: -This is the basic control with which you will work most of time. For example
  textbox, buttons etc. Now controls which are standalone control like button , text box ,
  labels etc are termed as content control. Now there are other controls which can hold
  other controls, for instance itemscontrols. Itemscontrol can have multiple textbox
  controls, label controls etc.
• Shape: – These controls help us to create simple graphic controls like Ellipse, line,
  rectangle etc.
• Panel: – These controls help to align and position the controls. For instance grid helps us
  to align in a table manner, stack panel helps for horizontal and vertical alignment.
• Content presenter: – This control helps to place any XAML content inside it. Used when
  we want to add dynamic controls on a WPF screen.

All the above four types of WPF controls finally inherit from the frameworkelement class of
WPF.
