How to Access control inside datagrid ColumnHeaderStyle?

in this sample:

   <Style x:Key="DataGridColumnHeaderStyle1" TargetType="{x:Type DataGridColumnHeader}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
                    <Grid Name="grdPeresenter" VerticalAlignment="Center" HorizontalAlignment="Stretch">
                       <TextBox x:Name="txtSearch" Grid.Row="1" BorderThickness="2"  PreviewMouseLeftButtonUp="grid1_PreviewMouseLeftButtonUp"  HorizontalAlignment="Stretch" TextChanged="TextBox_TextChanged" >
                           </TextBox>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

According to this answer : 

 var res = FindVisualChildren<TextBox>(grd).Where(t => t.Name == "txtSearch");

here yo can find all "txtSearch" headers textBox.

I'm sure it can get more direct way, but until then ..
