Все, что вам нужно сделать, добавить атрибут контейнера к каждому элементу сетки и применить alignItem, чтобы сделать его центром.
Ваш код должен выглядеть примерно так:
<Grid container direction="row" spacing={24}>
<Grid item xs={6}
container
direction="column"
justify="center"
alignItems="center"
className="abc">
<label>h</label>
</Grid>
<Grid item xs={6}
container
direction="column"
justify="center"
alignItems="center"
className="pqr">
<label>hnnn</label>
</Grid>
</Grid>

An SDF file is a Sql Server Mobile file. It is also referred to as Sql Server compact. It is predominantly used in mobile development but recently more and more common in single user desktop developments as well.
Visual Studio 2008 does not support Linq to Sql for Sql Server Mobile but the Framework does. You can find out more on implementing this here
You can find more on Sql Server Mobile here. The link will also help explain the differences between this and Mdf's, used by Sql Server.
There is also an article on building a Linq to Sql model for Wpf using Sql Mobile/Compact here
One of the main differences between a Sdf and Mdf is that until recently an Mdf could not be opened and treated like a normal file, whereas an Sdf is accessed as a file. However in Visual Studio this concept was reproduced by allowing Sql Server Data files which dynamically attaches the Mdf to a Sql Server Express session.
