【Silverlight】使用ChildWindow实现MessageBox

原创 Linux操作系统 作者:iDotNetSpace 时间:2009-08-03 13:57:29 0 删除 编辑

最近项目上需要实现一个询问提示消息框,但猛的发现人家Silverlight类库提供的MessageBox类只有简单的两个重载方法,百思不得其解,不知为什么不提供,没有办法只有自己做一个,其实不是很难办,因为Silverlight3以后提供了ChildWindow,下面是实现代码,希望对大家有用,请多多支持。

效果:


<controls:ChildWindow x:Class="SilverlightMsgBox.MsgBoxWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls" Width="400" Height="160" Title="MsgBox">
    
<Grid x:Name="LayoutRoot" Margin="2">
        
<Grid.ColumnDefinitions>
            
<ColumnDefinition Width="68"/>
            
<ColumnDefinition />
        
Grid.ColumnDefinitions>
        
<Grid.RowDefinitions>
            
<RowDefinition/>
            
<RowDefinition Height="Auto"/>
        
Grid.RowDefinitions>
        
<TextBlock x:Name="msgBlock" HorizontalAlignment="Left"  VerticalAlignment="Center" Grid.Column="1">TextBlock>
        
<Image x:Name="imgIcon" Width="32" Height="32" HorizontalAlignment="Center" VerticalAlignment="Center" Source="png/Message.png" />
    
Grid>
controls:ChildWindow>
