如何使用enter键提交登录详细信息

Question

我有一个基本的登录页面,

    <TextBox x:Name="UsernameInput" HorizontalAlignment="Left" TextWrapping="Wrap" Text="{Binding Username, Mode=TwoWay}" VerticalAlignment="Center" Grid.Row="0" Grid.Column="2" Width="400" />
    <PasswordBox HorizontalAlignment="Left" VerticalAlignment="Center" Password="{Binding Password, Mode=TwoWay}" Grid.Row="1" Grid.Column="2" Width="400"/>
    <TextBlock HorizontalAlignment="Right" TextWrapping="Wrap" Text="Username: " VerticalAlignment="Center" Margin="0,0,0,15" Grid.Row="0" Grid.Column="0" Style="{StaticResource SubheaderTextStyle}"/>
    <TextBlock HorizontalAlignment="Right" TextWrapping="Wrap" Text="Password: " VerticalAlignment="Center" Margin="0,0,0,15" Grid.Row="1" Grid.Column="0" Style="{StaticResource SubheaderTextStyle}"/>

    <Button Content="Login" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Row="2" Grid.Column="2" Height="50" Width="300" Command="{Binding LoginCommand}"/>

如果用户从密码字段中按Enter键,如何模拟按下的"登录"按钮？

谢谢!

Answer 1

你可以使用的KeyDown事件PasswordBox.

<PasswordBox KeyDown="txtPassword_KeyDown"/>

private void txtPassword_KeyDown(object sender, KeyRoutedEventArgs e)
{
    if (e.Key == Windows.System.VirtualKey.Enter)
        //TODO: do login
}
