在上一篇文章中我们将了替代Silverlight中MessageBox的MessageDialog控件,本篇文章将讲诉另外一种弹出提示窗口的控件Popup。

一、我们认识Popup控件的IsLightDismissEnabled属性，这个属性设置为true的时候，点击非Popup控件外任何区域将关闭Popup。

<Button Content="弹出窗口一" Name="btn1" Width="108"

Margin="161,96,0,0" VerticalAlignment="Top" Height="52" Click="btn1_Click"/>

<Popup x:Name="tip1" IsLightDismissEnabled="True"

HorizontalOffset="161" VerticalOffset="250">

<Grid Width="312" Height="200" >

<Grid.Background>

<ImageBrush ImageSource="./BG.png"></ImageBrush>

</Grid.Background>

<TextBlock Grid.Row="0" Foreground="White" Grid.Column="0"

FontSize="15" Height="Auto" HorizontalAlignment="Center"

Margin="0 20 0 0" VerticalAlignment="Top">

<Run>众芳摇落独暄妍，占尽风情向小园</Run>

<LineBreak/>

<LineBreak/>

<Run>疏影横斜水清浅，暗香浮动月黄昏</Run>

<LineBreak/>

<LineBreak/>

<Run>霜禽欲下先偷眼，粉蝶如知合断魂</Run>

<LineBreak/>

<LineBreak/>

<Run>幸有微吟可相狎，不须檀板共金樽</Run>

</TextBlock>

</Grid>

</Popup>

二、我们看Popup的显示和隐藏时的动画设置，具体类型有以下几种，具体效果可以自己下载实例并且修改实例来观看。

AddDeleteThemeTransition

ContentThemeTransition

EdgeUIThemeTransition

EntranceThemeTransition

PaneThemeTransition

PopupThemeTransition

ReorderThemeTransition

RepositionThemeTransition

<Button Content="弹出窗口二" x:Name="btn1_Copy" Width="108"

Margin="510,96,0,0" VerticalAlignment="Top" Height="52" Click="btn1_Copy_Click"/>

<Popup x:Name="tip2" IsLightDismissEnabled="True"

HorizontalOffset="510" VerticalOffset="250">

<Popup.ChildTransitions>

<TransitionCollection>

<AddDeleteThemeTransition></AddDeleteThemeTransition>

<ContentThemeTransition/>

<EdgeUIThemeTransition></EdgeUIThemeTransition>

<EntranceThemeTransition></EntranceThemeTransition>

<PaneThemeTransition></PaneThemeTransition>

<PopupThemeTransition></PopupThemeTransition>

<ReorderThemeTransition></ReorderThemeTransition>

<RepositionThemeTransition></RepositionThemeTransition>

</TransitionCollection>

</Popup.ChildTransitions>

<Grid Width="312" Height="200" >

<Grid.Background>

<ImageBrush ImageSource="./BG.png"></ImageBrush>

</Grid.Background>

<TextBlock Grid.Row="0" Foreground="Yellow" Grid.Column="0"

FontSize="15" Height="Auto" HorizontalAlignment="Center"

Margin="0 20 0 0" VerticalAlignment="Top">

<Run>莫笑农家腊酒浑，丰年留客足鸡豚</Run>

<LineBreak/>

<LineBreak/>

<Run>山重水复疑无路，柳暗花明又一村</Run>

<LineBreak/>

<LineBreak/>

<Run>萧鼓追随春社近，衣冠简朴古风存</Run>

<LineBreak/>

<LineBreak/>

<Run>从今若许闲乘月，拄杖无时夜叩门</Run>

</TextBlock>

</Grid>

</Popup></p> <p> <Button Content="弹出窗口三" x:Name="btn1_Copy1" Width="108"

Margin="850,96,0,0" VerticalAlignment="Top" Height="52" Click="btn1_Copy1_Click" />

<Popup x:Name="tip3" IsLightDismissEnabled="True" VerticalOffset="250"

HorizontalOffset="-312" HorizontalAlignment="Right">

<Popup.ChildTransitions>

<TransitionCollection>

<PaneThemeTransition />

</TransitionCollection>

</Popup.ChildTransitions>

<Grid Width="312" Height="200" >

<Grid.Background>

<ImageBrush ImageSource="./BG.png"></ImageBrush>

</Grid.Background>

<TextBlock Grid.Row="0" Foreground="Coral" Grid.Column="0"

FontSize="15" Height="Auto" HorizontalAlignment="Center"

Margin="0 20 0 0" VerticalAlignment="Top">

<Run>舍南舍北皆春水，但见群鸥日日来</Run>

<LineBreak/>

<LineBreak/>

<Run>花径不曾缘客扫，蓬门今始为君开</Run>

<LineBreak/>

<LineBreak/>

<Run>盘飧市远无兼味，樽酒家贫只旧醅</Run>

<LineBreak/>

<LineBreak/>

<Run>肯与邻翁相对饮，隔篱呼取尽馀杯</Run>

</TextBlock>

</Grid>

</Popup>

三、Popup的内容还可以直接继承于用户控件，以将用户控件直接弹出。下面的实例代码中UC1是一个用户控件，可下载源码观看

<Button Content="弹出窗口四" x:Name="btn1_Copy2" Width="108"

Margin="1150,96,0,0" VerticalAlignment="Top" Height="52" Click="btn1_Copy2_Click" />

<Popup x:Name="tip4" IsLightDismissEnabled="True"

HorizontalOffset="850" VerticalOffset="250">

<Popup.ChildTransitions>

<TransitionCollection>

<AddDeleteThemeTransition/>

</TransitionCollection>

</Popup.ChildTransitions>

<local:UC1/>

</Popup>
