Answer 1

Set the TextAlignment property to Center :

<DataGridTextColumn Header="Id" Binding="{Binding Id, Mode=TwoWay}" IsReadOnly="True" Width="100">
    <DataGridTextColumn.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="TextBlock.TextAlignment" Value="Center" />
        </Style>
    </DataGridTextColumn.CellStyle>
</DataGridTextColumn>
...

Try this:

 <DataGrid>
        <DataGrid.Columns>
            <DataGridTextColumn>
                <DataGridTextColumn.ElementStyle>
                    <Style TargetType="TextBlock">
                        <Setter Property="TextAlignment" Value="Center" />
                    </Style>
                </DataGridTextColumn.ElementStyle>
            </DataGridTextColumn>
        </DataGrid.Columns>
    </DataGrid>
