Вопрос:

Вот код TabControl

Я добавил другой пользовательский элемент управления в connectionspage в качестве первого элемента tabitem
public ConnectionsPage(PMPResponse response)
{
this.response = response;
InitializeComponent();
tabItems.Add(new TabItem { Header = "Connections", Content = new ResourceAccountDisplayUserControlCopy(response), TabIndex = 0 });
ConnectionsTab.ItemsSource = tabItems;
ConnectionsTab.SelectedIndex = 0;
LoadResourceUserControl();
}
У меня есть еще одно всплывающее окно внутри внутреннего usercontrol
<Grid>
<ToggleButton Name="OpenPopupButtonUserProfile" Background="Transparent" BorderBrush="Transparent" Height="20" VerticalAlignment="Center" Width="20">
<ToggleButton.Style>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="BorderThickness" Value="0"/>

<Button Height="20" Padding="0" Name="SortAscending" Click="SortAscending_Click" Background="Transparent" BorderBrush="Transparent" Foreground="Gray">Ascending</Button>
</ListBoxItem>
<Separator Height="0.5" Margin="-8,2,-7.6,2"/>
<ListBoxItem Height="25" Padding="5,0,5,0">
<Button Height="20" Padding="0" Name="SortDescending" Click="SortDescending_Click" Background="Transparent" BorderBrush="Transparent" Foreground="Gray">Descending</Button>
</ListBoxItem>
</ListBox>
</Popup>
</Grid>
Когда я нажимаю кнопку переключения внутреннего usercontrol, появляется всплывающее окно, когда я нажимаю внешнюю кнопку переключения, появляется всплывающее окно.
Но как только нажата внешняя кнопка переключения. при нажатии на внутреннюю кнопку переключения всплывающее окно внутри внутреннего usercontrol не отображается. но внутренняя кнопка переключения возвращает true . Кнопка переключения проверяется при нажатии на внешнюю кнопку переключения, оба всплывающих окна отображаются одновременно.
Я не знаю, что я делаю не так.
Комментарии:
1. Дважды проверьте опубликованный вами код. Первый раздел не имеет смысла, так как у вас есть
Setterнепосредственно внутриTabControl.Resources.2. @KeithStein Извини братан, что я пропустил строку при вставке <Style TargetType=»{x:Type TabControl}»> Now i have edited the question.
