how to edit listview row with a combo - wpf

Question

I have a ListView with rows on it. When I click on a particular cell, I want that selected cell to be editable with a combo box and the thing is I have done it, but the combox box still remains even after editing. I want the combo box to change back to textblock.
<Style TargetType="{x:Type FrameworkElement}"
x:Key="GridEditStyle">
<Setter Property="VerticalAlignment" Value="Center" />
<Setter Property="Visibility"
Value="{Binding Path=IsSelected,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type ListViewItem}},
Converter={StaticResource boolToVis},
ConverterParameter=True}" />
</Style>
<ComboBox SelectedItem="Present"
ItemsSource="{Binding ElementName=This,
Path=AvailablePublishers}"
Style="{StaticResource GridEditStyle}" />
code behind is
private ObservableCollection<string> _AvailablePublishers =
new ObservableCollection<string>();
public Student_Attendance()
{
InitializeComponent();
_AvailablePublishers.Add("Present");
_AvailablePublishers.Add("Absent");
_AvailablePublishers.Add("Late");
}
public ObservableCollection<string> AvailablePublishers
{ get { return _AvailablePublishers; } }
public class BoolToVisibilityConverter : IValueConverter
{
public object Convert(object value, Type targetType,
object parameter, System.Globalization.CultureInfo culture)
{
bool param = bool.Parse(parameter as string);
bool val = (bool)value;
return val == param ? Visibility.Visible : Visibility.Hidden;
}
public object ConvertBack(object value, Type targetType,
object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
plz help me out
thank you

You know if you used a DataGrid, you would't have to do anything for switching the viewing and editing templates, it's done automatically ... here's a sample to get you started:
<DataGrid ItemsSource="{Binding ...}">
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock DataContext="{Binding ...}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<ComboBox ItemsSource="{Binding ElementName=This, Path=AvailablePublishers}" SelectedItem="{Binding ...}"/>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>
