[英]Open WPF Popup on TextBox focus
當焦點在文本框上時,我想打開一個彈出窗口這是我寫的代碼:
<Window x:Class="Testpopup.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<StackPanel>
<TextBox x:Name="text" GotKeyboardFocus="text_GotKeyboardFocus" />
<Button Click="Button_Click" Content="but"/>
<Popup x:Name="popup" Width="100" Height="100" PlacementTarget="{Binding ElementName=text}"
StaysOpen="False">
<Grid>
<StackPanel>
<DatePicker />
<TextBox />
</StackPanel>
</Grid>
</Popup>
</StackPanel>
</Grid>
private void Button_Click(object sender, RoutedEventArgs e)
{
popup.IsOpen = true;
}
private void text_GotKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
popup.IsOpen = true;
}
如果我單擊按鈕一切正常如果我單擊文本框彈出打開和關閉
如果我刪除StaysOpen =“False”彈出窗口打開但從不關閉
我嘗試在打開它之前將重點放在彈出窗口上,但它也不起作用
你有什么主意嗎 ?
非常感謝,Nidal。
將以下綁定添加到Popup聲明:
StaysOpen="{Binding ElementName=text,Path=IsKeyboardFocused}"
這應該可以解決問題。
