How to get the object of specified row and colum in WPF's Grid?

The row and column properties for a WPF Grid are really attached dependency properties. So, certain static methods must be included inorder for those properties to be usable in XAML. You only need to loop through the children of the Grid to make sure you're going through the objects in the grid, and then you use those same methods to get the column and row of the object.

The following code is a simple example of how to do this. Please keep in mind that it runs under the assumption that each item has a column and row span of 1. In order to be on the safe side, you will also to have grab the spans of the objects' columns and rows, and do a little math to be sure an object overlaps the position you want.

foreach (UIElement item in someGrid.Children)
{
   int column = Grid.GetColumn(item);
   int row = Grid.GetRow(item);

   if (column == expectedColumn && row == expectedRow)
   {
      // Do something.
   }
}
