Great answer. My implementation (Generating array of Buttons in code then want indexed array thereof):

            Button[,] Buttons = new Button[8, endTimePlus1 - startTime];

        var buttons = controlGrid.Children.Cast<Button>();
        for (int i = 0; i < 8; i++)
        {
            for (int j = 0; j < endTimePlus1 - startTime; j++)
            {
                Buttons[i,j] =  buttons.Where(x => Grid.GetRow(x) == j && Grid.GetColumn(x) == i).FirstOrDefault();
            }
        }

UIElement FindByCell1(Grid g, int row, int col)
{
    var childs = g.Children.Cast<UIElement>()
    return childs.Where(x => Grid.GetRow(x) == row && Grid.GetColumn(x) == col).FirstOrDefault();
}

If there may be some elements in the same cell:

IEnumerable<UIElement> FindByCell(Grid g, int row, int col)
{
    var childs = g.Children.Cast<UIElement>()
    return childs.Where(x => Grid.GetRow(x) == row && Grid.GetColumn(x) == col);
}

In your case, This way - working directly with the elements in the UI - its very very not recommended, and its the extreme opposite of MVVM.
