Differences between DataContext and ItemsSource in WPF

In WPF, the DataContext and ItemsSource properties are commonly used for data binding. The key difference between DataContext and ItemsSource is how they are used to bind data to WPF controls.

DataContext

The DataContext property sets the data context for a WPF element, allowing all child elements to inherit this context. It is typically used to bind the entire data context for a given control or window.

ItemsSource

The ItemsSource property, on the other hand, is specifically used with items controls like ListBox, ComboBox, or ListView. It binds the collection of items that will be displayed in the control.

Therefore, the focus keyword in this context would be "DataContext" and "ItemsSource" in WPF.
