如何在DataTemplate中的WPF AutoCompleteBox容器中获取TextBlock的值？

下面是我的AutoCompleteBox XAML

    FilterMode="StartsWith"
    SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
    SelectionChanged='acLastName_SelectionChanged'
    ValueMemberPath="LastName">
        <my:AutoCompleteBox.ItemTemplate>
            <DataTemplate x:Name='UserDetails'>
                <StackPanel Orientation="Horizontal">
                    <TextBlock x:Name='UserId' Text="{Binding UserDetailsId}"/>
                    <TextBlock Text="{Binding LastName}" />
                    <TextBlock Text="{Binding FirstName}" />
                    <TextBlock Text="{Binding UserId}" />
                    <TextBlock Text="{Binding Comapany}" />
                </StackPanel>
           </DataTemplate>
        </my:AutoCompleteBox.ItemTemplate>
</my:AutoCompleteBox>

Answer 1

acLastName.SelectedItem将是您的UserDetails对象。

因此，通过以下方式投射该小狗并访问UserDetailsId：

((UserDetails)acLastName.SelectedItem).UserDetailsId
