How can i create search text box for each coloumn in data gr

Question

This i my xaml code

<DataGrid Name="ExcelSheetView" Visibility="Hidden" HorizontalAlignment="Left" Margin="15,225,0,0" VerticalAlignment="Top" Height="155" Width="auto" BeginningEdit="DataCellEditing_Event" CellEditEnding="CellEditingEnd_Event" AutoGenerateColumns="False">

<TextBox Text="{Binding TamName}" BorderThickness="0" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

</DataGrid.Columns>

I am Using Observable Collection property to dyanmically bind the item source property of data grid

private ObservableCollection<MailingListStructure> ExcelSheetListDetails = new ObservableCollection<MailingListStructure>(DataList);

the above collections property i will set like datagrid.ItemsSource = ExcelSheetListDetails; In C# back End

But my Problem is I need to have empty text box(search Box) at the start of data rows (Below each coloumn header)

How to implement in this xaml or c#?Is it possible in wpf? i.e. the first row in the data rows must have empty text boxes() (only first row below coloumn header )

or i have create search box outside datagrid is the only way?Any help will be appreciated.
