Window1的后台代码：：

using System;using c;using ;using ;using s;using ls;using ;using nts;using ;using ;using g;using tion;using ;using entModel;namespace ComboBoxBindings{ ///

public partial class Window1 : Window { private int index;

public Window1() { InitializeComponent(); ( new Dog( " Dog1 " )); ( new Dog( " Dog2 " )); ( new Dog( " Dog3 " )); ( " EducationGrade1 " ); ( " EducationGrade2 " ); ( " EducationGrade3 " ); this .ource = persons; } public List < String > types = new List < String > (); public List < String > EducationTypes { get

代码

{ return types; } } public BindingList < Dog > dogs = new BindingList < Dog > (); public BindingList < Dog > Dogs { get

{ return dogs; } } public BindingList < Person > persons = new BindingList < Person > (); public BindingList < Person > Persons { get

{ return persons; } } private void comboBoxInListView_Loaded( object sender, RoutedEventArgs e) { ComboBox box = sender as ComboBox; ource = null ; ource = dogs; } private void btnAdd_Click( object sender, RoutedEventArgs e) { ( new Person( ++ index)); } private void btnDel_Click( object sender, RoutedEventArgs e) { while ( this . > 0 ) { ((Person) this .edItems[ 0 ]); } } private void comboBoxInWnd_SelectionChanged( object sender, SelectionChangedEventArgs e) { ComboBox box = sender as ComboBox; this .ntext = null ; this .ntext = edItem; } }}
