Wpf datagrid column size is not adjusted according to the width of the content present in rows

We have one datagrid in wpf application.

<DataGrid x:Name="dgvOrders" BorderThickness="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Visibility="Visible" Cursor="Hand"
       CanUserAddRows="False"
       ColumnWidth="Auto"
       FontWeight="Normal" 
       Margin="5,5,5,0" 
       AlternationCount="2" 
       DragOver="dgvOrders_DragOver" 
       Drop="dgvOrders_Drop"
       DragEnter="dgvOrders_DragEnter"
       AllowDrop="True"
       Height="Auto"
       MaxHeight="380"
       PreviewMouseLeftButtonDown="dgvOrders_PreviewMouseLeftButtonDown"
       SelectionMode="Extended" GridLinesVisibility="Horizontal" 
       HorizontalGridLinesBrush="#FFD8D8D8" VerticalGridLinesBrush="#FFD8D8D8"
       PreviewKeyDown="dgvOrders_PreviewKeyDown" 
       AutoGenerateColumns="False">
       <DataGrid.RowStyle>
           <Style TargetType="DataGridRow">
            <Style.Triggers>
                  <DataTrigger Binding="{Binding IsDisposed}" Value="False">
                       <Setter Property="Background" Value="LightGreen" />
                  </DataTrigger>
            </Style.Triggers>
           </Style>
        </DataGrid.RowStyle>
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="dgcRouteIndex" Binding="{Binding RouteOrderIndex, Mode=OneWay}" Header="Tour Reihenfolge" Width="Auto" Visibility="Hidden" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding FullName, Mode=OneWay}" Header="Name" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding Address.Zip, Mode=OneWay}" Header="PLZ" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding Address.City, Mode=OneWay}" Header="ORT" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding Address.Street, Mode=OneWay}" Header="Straße" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding BirthDate, StringFormat=\{0:dd.MM.yyyy\}, Mode=OneWay}" Header="Geburtsdatum" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding IsChild, Converter={StaticResource BooleanToJaNeinConverter},Mode=OneWay}" Header="Kind" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding IsSecondVisit, Converter={StaticResource BooleanToJaNeinConverter},Mode=OneWay}" Header="Verzögerung" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding DeadlineDate, StringFormat=\{0:dd.MM.yyyy\}, Mode=OneWay}" Header="Fristdatum" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding IsNoCurePossible, Converter={StaticResource BooleanToJaNeinConverter},Mode=OneWay}" Header="Anlass" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding IsSecondVisit, Converter={StaticResource BooleanToJaNeinConverter},Mode=OneWay}" Header="Gutachtenart" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding OpinionDate, StringFormat=\{0:dd.MM.yyyy\}, Mode=OneWay}" Header="Begutachtungsdatum" Width="Auto" CanUserResize="False"/>
            <DataGridTextColumn Binding="{Binding Info, Mode=OneWay}" Header="Info" Width="Auto"/>
            <DataGridTextColumn x:Name="dgcRouteDistance" Binding="{Binding RoutingDistance,Mode=OneWay}" Header="Kilometers" Width="Auto" Visibility="Hidden" CanUserResize="False"/>
           </DataGrid.Columns>
  </DataGrid>

We have functionality that on scrolling the mouse wheel by pressing control key, font size of text present in the application increases (Scroll Up : increase, Scroll Down : decrease).

When we scrolls up then font size of text present in the data grid row increases, and also the width of that respective columns increases.

But when we scrolls down, font size of text present in the data grid row decreases, but column width does not decrease.

Can anybody have the solution ?

I'm using this loop

foreach (ColumnHeader c in table.Columns)
{
    c.Width = -2;
}

Width -2 is adjusting width to content of header and cells.
