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>

效果图:

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"> <Path.Data> <PathGeometry Figures="M 10,0 L 10,0,0,5 L 0,5,10,10"/> </Path.Data> </Path> </Canvas> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>
