If SelectionUnit="Cell" try this:

    string cellValue = GetSelectedCellValue();

Where:

    public string GetSelectedCellValue()
    {
        DataGridCellInfo cellInfo = MyDataGrid.SelectedCells[0];
        if (cellInfo == null) return null;

        DataGridBoundColumn column = cellInfo.Column as DataGridBoundColumn;
        if (column == null) return null;

        FrameworkElement element = new FrameworkElement() { DataContext = cellInfo.Item };
        BindingOperations.SetBinding(element, TagProperty, column.Binding);

        return element.Tag.ToString();
    }

Seems like it shouldn't be that complicated, I know...

Edit: This doesn't seem to work on DataGridTemplateColumn type columns. You could also try this if your rows are made up of a custom class and you've assigned a sort member path:

    public string GetSelectedCellValue()
    {
        DataGridCellInfo cells = MyDataGrid.SelectedCells[0];

        YourRowClass item = cells.Item as YourRowClass;
        string columnName = cells.Column.SortMemberPath;

        if (item == null || columnName == null) return null;

        object result = item.GetType().GetProperty(columnName).GetValue(item, null);

        if (result == null) return null;

        return result.ToString();
    }
