Resize columns not working in wpf DataGrid

I want to make data grid columns re-sizable based on it's content. I have tried setting CanUserResizeColumns to true but it's not working. If i put this in new wpf project then it would work perfectly but in my exisiting wpf project it's not working.

Here's what I am doing :

<UserControl>
 <Grid>
   <ScrollViewer
    <DataGrid Name="dgAllJob" CanUserResizeColumns="True"
                                  Width="{Binding RelativeSource={RelativeSource Self}, Path=Parent.ActualWidth}"                                    
                                    ScrollViewer.HorizontalScrollBarVisibility="Auto"                                   
                                    ScrollViewer.VerticalScrollBarVisibility="Auto"   
                                    ScrollViewer.CanContentScroll="False"
                                    ColumnWidth="*"                                    
                                    HorizontalAlignment="Stretch"          
                                    CanUserAddRows="False"                 
                                    AutoGenerateColumns="False"
                                  CanUserSortColumns="False">
                            <DataGrid.Columns>
                                <DataGridTextColumn Header="Job No"  Binding="{Binding JobNumber,Mode=OneTime}"/>
                                <DataGridTextColumn Visibility="Collapsed" Header="Start Date" Width="80" Binding="{Binding ActualStartDate,StringFormat=dd/MM/yyyy,Mode=OneTime}"/>
                                <DataGridTextColumn Header="Client Name" Binding="{Binding BillName,Mode=OneTime}" CanUserResize="True"/>
                                <DataGridTextColumn Header="Postal Address"  Binding="{Binding BillAddress,Mode=OneTime}" CanUserResize="True"/>
                                <DataGridTextColumn Header="Suburb"  CanUserResize="True" Binding="{Binding BillSuburb,Mode=OneTime}"/>
                                <DataGridTextColumn Header="Site Suburb" CanUserResize="True" Binding="{Binding SiteSuburb,Mode=OneTime}" />
                                <DataGridTextColumn Header="Contact Name" Binding="{Binding ContactName,Mode=OneTime}" CanUserResize="True"/>
                                <DataGridTextColumn Header="Estimator"  Binding="{Binding Estimator,Mode=OneTime}" CanUserResize="True"/>
                                <DataGridTextColumn Header="Installer" Binding="{Binding Installer,Mode=OneTime}" CanUserResize="True"/>
                            </DataGrid.Columns>
      </DataGrid>
     </ScrollViewer>
   </Grid>
</UserControl>

can anyone tell what I am missing or what is wrong here ???

Since you are putting your DataGrid in a ScrollViewer, the DataGrid will be sized to the minimum. Try disabling the HorizontalScrollBarVisibility or take it out of the ScrollViewer.

Any custom styles in your exisiting project may disable the resize functionality.

You could try to for example set the ColumnHeaderStyle property to x:Null or simply remove the custom Style.
