从一个文本框获取值到另一个文本框 XAML

Question

我创建了一个文本框，聚焦时会弹出一个弹出框，其中包含其他文本框的选项。按下时会关闭弹出框。但我希望从任何文本中获取值我选择并添加到原始文本框中的框。这可能吗？我是 wpf 的新手所以请原谅我！

到目前为止，这是我的代码。

 <Grid>

    <StackPanel Margin="0,51,0,-51">
        <TextBox  x:Name="text" GotKeyboardFocus="text_GotKeyboardFocus" Margin="158,0,169,0" Height="24" Text="Select Your Time..." />

        <Popup x:Name="popup" Width="282" Height="300" PlacementTarget="{Binding ElementName=text}">
            <Grid>
                <StackPanel>
                    <TextBox  x:Name="text2" Background="White" Margin="10" GotKeyboardFocus="text_GotKeyboardFocus2" Cursor="Arrow" Height="24" Text="1 second" />
                    <TextBox  x:Name="text3" Background="White" Margin="10" GotKeyboardFocus="text_GotKeyboardFocus2" Cursor="Arrow" Height="24" Text="2 second" />
                    <TextBox  x:Name="text4" Background="White" Margin="10" GotKeyboardFocus="text_GotKeyboardFocus2" Cursor="Arrow" Height="24" Text="3 second" />
                    <TextBox  x:Name="text5" Background="White" Margin="10" GotKeyboardFocus="text_GotKeyboardFocus2" Cursor="Arrow" Height="24" Text="4 second" />
                    <TextBox  x:Name="text6" Background="White" Margin="10" GotKeyboardFocus="text_GotKeyboardFocus2" Cursor="Arrow" Height="24" Text="5 second" />
                </StackPanel>
            </Grid>
        </Popup>

    </StackPanel>




</Grid>




 private void text_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
    {
        popup.IsOpen = true;
    }

    private void text_GotKeyboardFocus2(object sender, RoutedEventArgs e)
    {
        popup.IsOpen = false;
    }

Answer 1

希望我明白你的意思。
只需将 text.Text = (sender as TextBox).Text; 添加到您的第二个事件处理程序，如下所示：

private void text_GotKeyboardFocus2(object sender, RoutedEventArgs e)
{
     popup.IsOpen = false;
     text.Text = (sender as TextBox).Text;
}

祝你好运。
