The following are some of the important things to know about the UniformGrid All the cells of a UniformGrid are always the same size as all the other cells regardless of whether the UniformGrid changes size or shape. Each cell contains a single element. Elements are added to the cells in the order in which they are listed in listing. You create the cells by specifying the number of rows and columns in the UniformGrid element. The following code creates a UniformGrid with two rows and two columns. It then populates each cell with a button.

The WrapPanel places its elements in rows or columns and wraps to a new row or column when the line reaches the end of the panel. The DockPanel allows its elements to select a side on which to adhere. The Grid comprises cells formed from rows and columns. This is the most powerful of the panels we covered. The Canvas allows you to associate elements with one of its corners. The UniformGrid produces a simple grid with cells that are all the same size. .
