Defines a flexible grid area that consists of columns and rows. Child elements of the Grid are measured and arranged according to their row/column assignments (set by using Grid.Row and Grid.Column attached properties) and other logic.

### Attached Properties

Grid is the host service class for several attached properties. These attached properties enable child elements to report how they should be positioned in their Grid parent.

|------------------------|---------|--------------------------------------------------------------------------------------------------------------|
| `Grid.Column`          | Integer | The column alignment of an element when child layout is processed by a parent Grid layout container.        |
| `Grid.ColumnSpan`      | Integer | A value that indicates the total number of columns that the element content spans within a parent Grid.     |
| `Grid.Row`             | Integer | The row alignment of an element when child layout is processed by a parent Grid layout container.           |
| `Grid.RowSpan`         | Integer | A value that indicates the total number of rows that the element content spans within a parent Grid.       |
