To accomplish a variable grid, the VariableSizedWrapGrid.ColSpan and RowSpan properties must be set on the GridViewItem. Unfortunately, it is impossible to bind to the GridViewItem directly. As a result, it is necessary to create a custom GridView inheriting from GridView and implementing PrepareContainerForItemOverride. The resulting control behaves like a standard GridView with the exception that it sets the GridViewItem ColSpan and RowSpan attached properties.
Look: WrapGrid implementation
Look: VariableSizedWrapGrid implementation
Implementing the Variable grid includes three important steps: 1) inheriting GridView and implementing the PrepareContainerForItemOverride method, 2) changing the ItemPanelTemplate to be a VariableSizedWrapGrid, and 3) include custom ColSpan and RowSpan properties in the models you bind to the repeater. That last one is important.

A unique UI is important to make your application stand out. Changing up the grid from the standard, vanilla, boring grid is a great start. Use these techniques to implement the variable grid into your app and start making a splash!
Best of luck!
