UniformGrid has a namespace System.Windows.Controls.Primitives. Good thing is in UniformGrid is it displays child elements in columns and rows of the same size. The order of the elements is given by it is order they have been added.

Here is a simple example a UniformGrid has two rows and two columns with four Image controls.

Result looks like this.

If I add _disibledevent="Verdana, Arial, Helvetica, sans-serif">Cool control.
