KATAMINO PROJECT

I'm building a game called KATAMINO following a course project and I'm currently having a problem displaying my parts in XAML. I can display a part in a grid with an X :NAME My parts are broken down into lists of cells, which are themselves items with an x, y attribute and a string value. My goal is already to redo my grids in a cleaner way, but also to be able to display my parts in 55 grids in a 250auto grid. So if you can give me a way of browsing my grid with all my piece grids: ( <Grid ColumnDefinitions=“,,,,,,,,,,,” RowDefinitions=“250” Grid.Row=“2” > ) Or give me an equivalent way please If attached some screenshots to give you some context
