Resizable

Resizable

If you want to enable live resize operations for a UI element, wrap that element into a Resizable widget. In this demo, you can resize the DataGrid. Try to drag the handles on the grid's edges.

Configure the following properties to specify resize operation constraints:

You can display resize handles on edges or corners. Use the following keywords to set up the handles property: top, bottom, left, and right. If you specify two adjacent sides (for example, "bottom right"), the control displays a handle in the corner.

The keepAspectRatio property specifies whether a corner handle resizes content proportionally. Set this property to false to allow free-form resize operations.
