Доброго времени суток,Уважаемые. Вопрос такой: Имеется ListView со своим стилем. При добавлении ListViewItem в окно View событие IsSelected отрабатывает верно, т.е. в фокусе тот элемент которые нужно. При Binding'e же Select'ится только первый элемент по триггеру и не "отлипает" при всякических уговорах). Binding пробовал организовать как на ObservableCollection<string> так и на CollectionViewSource,но видимо это только на некоторую производительность может влиять. СобсТвенно как выглядит ListView во View | Код |
<ListView Margin="10" Width="Auto" ItemsSource="{Binding Names,UpdateSourceTrigger=PropertyChanged}">
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn DisplayMemberBinding="{Binding}" Header="Дата" Width="auto"/>
<GridViewColumn DisplayMemberBinding="{Binding}" Header="Номер" Width="50"/>
<GridViewColumn Header="Стадия" Width="75">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Grid DataContext="{Binding}" HorizontalAlignment="Center" Height="50">
<TextBlock Text="{Binding}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding}" Header="Статус" Width="auto" />
<GridViewColumn DisplayMemberBinding="{Binding}" Header="Дата и время последней отправки на сервер" Width="auto" />
</GridView>
</ListView.View>
<!--<i:Interaction.Triggers>
<i:EventTrigger EventName="SourceUpdated">
<ei:CallMethodAction TargetObject="{Binding}" MethodName="Submit"/>
</i:EventTrigger>
</i:Interaction.Triggers>-->
</ListView>

Сам Байндинг проходит успешно. И Hover отрабатывает на TextBlock'e верно. Вопрос такой почему UIElement.Opacity ставится в соответствие первый элемент. Ведь каждый Item обернут в grid. Вопрос снимаю) Беда как раз была в баиндинге)) Я ссылку на один и тот же объект передавал. Будьте внимательны при работе с коллекциями) И я тоже буду внимателен)) Всем спасибо) Это сообщение отредактировал(а) qwerty123456 - 2.2.2013, 18:16 |
ListView, Отработка триггера выделения в MVVM, Неверно отрабатывает событие IsSelected
