Box
Documentation
The Box widget allows you to arrange various elements within it. Separate and adaptive, the Box widget acts as a building block for the layout. In this demo, you can see how the widget is used to layout different elements on a page.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
