Columns and rows that are defined within a can take advantage of Star sizing to distribute remaining space proportionally. When Star is selected as the height or width of a row or column, that column or row receives a weighted proportion of the remaining available space. This is in contrast to Auto, which distributes space evenly based on the size of the content that is within a column or row. This value is expressed as * or 2* when you use Extensible Application Markup Language (XAML). In the first case, the row or column would receive one times the available space, while in the second case, the row or column would receive two times the available space, and so on. For additional information about star sizing, see the Use Star Sizing Sample sample. By combining this technique to proportionally distribute space with a HorizontalAlignment and VerticalAlignment value of Stretch, it is possible to partition layout space by percentage of screen space. is the only layout panel that can distribute space in this manner.
By default, rows and columns take up the least amount of space necessary to accommodate the largest content within any cell contained in a given row or column. For example, if a column has one cell with a long word like "hippopotamus" contained within it but all the other cells in the column have smaller words like "dog", the width of the column will be the width of the largest word (hippopotamus).
You can precisely position child elements of a by using a combination of the Margin property and alignment properties.
Child elements of a are drawn in the order in which they appear in markup or code. As a consequence, layered order (also known as z-order) can be achieved when elements share the same coordinates.
and Table share some common functionality, but each can be applied in appropriate scenarios to better use its built-in features. adds elements based on a row and column index; Table does not. The element allows layering of content, where more than one element can exist within a single cell. Table does not support layering. Child elements of a can be absolutely positioned relative to the upper-left corner of their "cell" boundaries. Table does not support this feature. also offers more flexible resizing behavior than Table.
If a child element is added to a column within a , and the column has its Width property set to Auto, the child will be measured without restrictions. This behavior can prevent horizontal scroll bars from displaying if a ScrollViewer is being used, as the child element is measured as unbounded. For purposes of display, the child is clipped rather than scrolled.
Panel elements do not receive focus by default. To compel a panel element to receive focus, set the Focusable property to true.

|How to: Create a Grid Element||The following example shows how to create and use an instance of by using either Extensible Application Markup Language (XAML) or code. This example uses three ColumnDefinitions and three RowDefinitions to create a grid that has nine cells, such as in a worksheet. Each cell contains a TextBlock element that represents data, and the top row contains a TextBlock with the ColumnSpan property applied. To show the boundaries of each cell, the ShowGridLines property is enabled.|
