Windows Phone using Grid

I have a grid with 7 rows and 7 columns. I want to put in each cell a control dynamically.

To add the controls I use this code

Rectangle newRectangle = new Rectangle();

newRectangle.Tap += new EventHandler<GestureEventArgs>(Rectangle_KeyDown);
newRectangle.Fill = HighlightColor;

Grid.SetColumn(newRectangle, i);
Grid.SetRow(newRectangle, ii);

grid1.Children.Add(newRectangle);

How can I get one of those controls from position x,y?

I thought something like 

Grid.GetColumn( ?? );
Grid.GetRow( ?? );

But I don't know how to continue.

I realy hope someone can help me.

I am not sure what you are trying to accomplish there but I might suggest a different, cleaner approach that might work for you.

It involves using a ListBox with a UniformGrid as the ItemsPanelTemplate. You would then create a Collection and set it as the ItemsSource for this List. You can now populate your list with your Controls using a simple transformation from a bi dimensional perspective (col, row) to a single dimension list (your list). Setting and retrieving the controls is now as simple as that transformation.

There is no built in function for that so you should do the searching manually. But you can easily write such search function e.g with Linq:

var rectangleAtXy = grid.Children.OfType<Rectangle>()
    .SingleOrDefault(c => Grid.GetColumn(c) == x && Grid.GetRow(c) == y);

There is no function for this. You have to read the attached properties Row amd Column of the grid's children to determine in which cell they are in.
