WPF主動隱蔽的新聞框的實例代碼。本站提示廣大學習愛好者：（WPF主動隱蔽的新聞框的實例代碼）文章只能為提供參考，不一定能成為您想要的結果。以下是WPF主動隱蔽的新聞框的實例代碼正文
(鼠標放上去將一向顯示，移開動畫持續)，供給normal和error兩種邊框。
引見：傳統切實其實定，撤消,OK,CANCAL之類的對話框太繁瑣了，因為項目須要而出生的仿手機式提醒對話框。固然傳統的對話框項目中也有，這裡就不做引見了。
進場和登場動畫做得很簡略，就用Blend隨意鼓搗了一番，遷就用吧。
預覽後果以下：
思緒其實很簡略：將窗體通明化->結構和款式設計->後台傳值挪用。
預備任務：Microsoft.Expression.Interactions.dll和System.Windows.Interactivity.dll的援用。Blend中年夜多半行動須要須要這2個dll，必備啊！
1，將窗體通明化，無邊框化：（在.net 4.5中 拖動和縮放窗體不再用本身寫代碼了，集成的 <WindowChrome/>便可以完成拖動縮放窗體等諸多功效。）
症結設置以下：
AllowsTransparency="True" HorizontalAlignment="Center" Background="Transparent" xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions" Window
2，結構，重要包含初始結構和動畫過渡2個方面：
靜態界面結構：
<Grid HorizontalAlignment="Center" VerticalAlignment="Top" x:Name="back">
<Border Padding="38 0" x:Name="br" HorizontalAlignment="Center" VerticalAlignment="Center">
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseEnter">
<ei:ControlStoryboardAction Storyboard="{StaticResource ShowSb}" ControlStoryboardOption="Stop"/>
</i:EventTrigger>
<i:EventTrigger EventName="MouseLeave">
<ei:ControlStoryboardAction Storyboard="{StaticResource MouseLeave}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
<Grid HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid.RowDefinitions>
<RowDefinition Height="12"></RowDefinition>
<RowDefinition Height="auto"></RowDefinition>
<RowDefinition Height="12"></RowDefinition>
</Grid.RowDefinitions>
<Border Visibility="Visible" x:Name="grid1" Grid.RowSpan="3" RenderTransformOrigin="0.5,0.5" BorderBrush="#00A0E9" BorderThickness="1" CornerRadius="8">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</Border.RenderTransform>
<Border.Background>
<LinearGradientBrush EndPoint="1,1" MappingMode="RelativeToBoundingBox" StartPoint="0,0">
<GradientStop Color="#EFF0F2" Offset="0.75"/>
<GradientStop Color="#EFF0F2" Offset="0.25"/>
<GradientStop Color="#EFF0F2" Offset="1"/>
<GradientStop Color="#EFF0F2"/>
</LinearGradientBrush>
</Border.Background>
</Border>
<Border x:Name="grid2" Visibility="Visible" Opacity="1" Grid.RowSpan="3" RenderTransformOrigin="0.5,0.5" BorderBrush="#F35150" BorderThickness="1" CornerRadius="8">

<GradientStop Color="#EFF0F2" Offset="0.25"/>
<GradientStop Color="#EFF0F2" Offset="1"/>
<GradientStop Color="#EFF0F2"/>
</LinearGradientBrush>
</Border.Background>
</Border>
<TextBlock Margin="38 0 38 0" Grid.Row="1" FontSize="16" Foreground="#64676d" x:Name="tb" Text="{Binding Message,RelativeSource={RelativeSource AncestorType=Window},FallbackValue=掉敗信息}" TextWrapping="Wrap" MinWidth="200" VerticalAlignment="Center" HorizontalAlignment="Center" RenderTransformOrigin="0.5,0.5" MaxWidth="600" TextAlignment="Center" FontFamily="Microsoft YaHei">
<TextBlock.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</TextBlock.RenderTransform></TextBlock>
</Grid>
</Grid>
</Border>
</Grid>
進入和加入的動畫掌握：
<Storyboard x:Key="ShowSb" Completed="Storyboard_Completed">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="grid1">
<EasingDoubleKeyFrame KeyTime="0" Value="{Binding YOffSet}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="grid2">
<EasingDoubleKeyFrame KeyTime="0" Value="{Binding YOffSet}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="tb">
<EasingDoubleKeyFrame KeyTime="0" Value="{Binding YOffSet}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="MouseLeave" Completed="Storyboard_Completed">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="grid1">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="grid2">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="tb">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="grid1">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="grid2">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)" Storyboard.TargetName="tb">
<EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="{Binding YOffSet}"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
留意：鼠標挪動上去停滯動畫和移出後疾速消逝的代碼為：
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseEnter">
<ei:ControlStoryboardAction Storyboard="{StaticResource ShowSb}" ControlStoryboardOption="Stop"/>
</i:EventTrigger>
<i:EventTrigger EventName="MouseLeave">
<ei:ControlStoryboardAction Storyboard="{StaticResource MouseLeave}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
後台代碼邏輯：
private bool iserror = false;
public void Show(string messageBoxText, bool iserror = false)
{
this.iserror = iserror;
this.Message = messageBoxText;
this.Show();
}
public OnlyShowMessageBox()
{
InitializeComponent();
this.DataContext = new model() { YOffSet = -300d };
this.Loaded += (y, k) =>
{
this.Top = 41;
this.Left = (SystemParameters.WorkArea.Width) / 2 - this.ActualWidth / 2;
if (iserror)
{
this.grid.Visibility = Visibility.Collapsed;
}
else { this.grid.Visibility = Visibility.Collapsed; }
(this.Resources["ShowSb"] as Storyboard).Begin();
};
}
private void Storyboard_Completed(object sender, EventArgs e)
{
this.Close();
}
個中 ：
public class model : ModelBase
{
private double YOffset;
public double YOffSet
{
get { return YOffset; }
set
{
YOffset = value;
RaisePropertyChangedEvent("YOffSet");
}
}
}
個中ModelBase在 可分組的選擇框控件(MVVM下)(Toggle款式 仿制單選框RadioButton，復選框CheckBox功效) 中有引見。
最初，挪用辦法：
new OnlyShowMessageBox().Show("請留意：後方高能，制止入內！", false);
或許
new OnlyShowMessageBox().Show("不存在此對象！", true);
