Answer 1

Add SelectedItem, SelectedValue in your DataGrid.

And in your view model

private string _selectedValue;
public string SelectedValue
{
    get
    {
        return _selectedValue;
    }
    set
    {
        _selectedValue = value;
        NotifyPropertyChanged("SelectedValue");
    }
}

private DataTable sizeQuantityTable;
public DataTable SizeQuantityTable
{
    get
    {
        return sizeQuantityTable;
    }
    set
    {
        sizeQuantityTable = value;
        NotifyPropertyChanged("SizeQuantityTable");
    }
}

You can use SelectedItem as well, that is preferred.
