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>
最后如需源码请点击 Win8Popup_jb51.net 下载。效果如下：
