# ScrollViewer

The `ScrollViewer` control scrolls its content if the content is bigger than the space available. A `ScrollViewer` cannot be contained in a control that has infinite height or width (depending on scrolling direction) such as a `StackPanel`. To avoid it, you can either set fixed Height/Width or MaxHeight/MaxWidth or choose another container panel.

## ScrollChaining

If you have one `ScrollViewer` nested inside another `ScrollViewer` and the user hits any limit of the inner `ScrollViewer`, you can specify if the parent `ScrollViewer` should continue with the scroll event or not. You can enable or disable this behavior with the attached property `ScrollViewer.IsScrollChainingEnabled=[true|false]`. The default value is `true`.

This property is available from these Controls:

* ScrollViewer
* DataGrid
* ListBox
* TextBox
* TreeView
