Всем добрый день! Произвожу биндинг из бд через CollectionViewSource и BindingListCollectionView к ListView через ItemsSource, но получается так, что при начальном отображении элементы все одинаковые, а при выборе(фокусе) другого Item'а, значения всех строк меняются на выбранный Item, странно очень. Вот C# код: | Код |
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;
namespace WpfApplicationDiplom
{
/// <summary>
/// Interaction logic for PersonListWindow.xaml
/// </summary>
///
public partial class PersonListWindow : Window
{
private CollectionViewSource MasterViewSource;
private BindingListCollectionView MasterView;
public PersonListWindow()
{
InitializeComponent();
}
void GetData<T>(T query)
{
this.MasterViewSource = (CollectionViewSource)this.FindResource("MasterView");
this.MasterViewSource.Source = query;
this.MasterView = (BindingListCollectionView)this.MasterViewSource.View;
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
ListView1.Items.Clear();
MasterViewSource = null;
MasterView = null;
var q = (from p in App.db.workers
select new { fio = p.first_name + ' ' + p.last_name + ' ' + p.patronymic, profession = p.profession });
GetData(q);
}
private void button2_Click(object sender, RoutedEventArgs e)
{
this.Close();
PersonInfoWindow piw = new PersonInfoWindow();
piw.Show();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
if (this.MasterView.CurrentPosition > -1)
{
worker s = App.db.workers.ToList()[this.MasterView.CurrentPosition];
App.db.workers.DeleteOnSubmit(s);
this.MasterView.RemoveAt(this.MasterView.CurrentPosition);
App.db.SubmitChanges();
}
}
private void Item_GotFocus(object sender, RoutedEventArgs e)
{
ListViewItem item = ((ListViewItem)(sender));
this.ListView1.SelectedItem = item.DataContext;
//ListView1.Items.Refresh();
}
private void button3_Click(object sender, RoutedEventArgs e)
{
this.MasterView.MoveCurrentToPrevious();
}
private void button4_Click(object sender, RoutedEventArgs e)
{
this.MasterView.MoveCurrentToNext();
}
}
}

А вот XAML код: | Код |

Событие Item_GotFocus никак не влияет. Есть у меня привязка данных к комбобоксу и там вот как раз такого повторения нет и все отлично. |
