本文实例为大家分享了WPF气泡提示框的具体代码，供大家参考，具体内容如下
直接上代码
<TextBox Name="account" GotFocus="account_GotFocus" LostFocus="account_LostFocus" Style="{StaticResource LabelTextBox}" xl:ControlAttachProperty.Label="用户名:" Foreground="Black" Margin="10,10,273,271" Width="Auto" />
先在前台创建一个TextBox,然后各种附加的属性加上去:如图所示
<Popup Name="pop3" AllowsTransparency="True" StaysOpen="True" PopupAnimation="Fade" IsOpen="False" PlacementTarget="{Binding ElementName=account}" Placement="Right" >
<Label Style="{StaticResource tipLable}">
<StackPanel Orientation="Horizontal">
<Label Content="请输入用户名"/>
</StackPanel>
</Label>
</Popup>

样式代码:
<Style TargetType="Label" x:Key="tipLable">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Label}">
<Grid>
<Border CornerRadius="4" BorderBrush="Black" BorderThickness="1" VerticalAlignment="Top" Margin="8.5,0,0,0" Background="Yellow" HorizontalAlignment="Left" Padding="5">
<ContentPresenter />
</Border>
<Canvas Width="10" Height="10" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,10,0,0" Background="Transparent">
<Path Stroke="Black" StrokeThickness="0.5" Fill="Yellow">
