WPF自定义一个MessageBox

WPF的MessageBox太丑了，自己定义了一个。

这是效果：

 

XAML:

< Window  x:Class ="AgileToDo.UMessageBox"
        xmlns ="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x ="http://schemas.microsoft.com/winfx/2006/xaml"
        Title ="UMessageBox"  Height ="130"  Width ="280"  WindowStyle ="None"    Background =" {x:Null} "   
        ResizeMode ="NoResize"   x:Name ="main"
        AllowsTransparency ="True"  WindowStartupLocation ="CenterScreen" >
     < Window.Triggers >
         < EventTrigger  RoutedEvent ="Window.Loaded"   >
             < BeginStoryboard >
                 < Storyboard  Name ="sbOpShow" >
                     < DoubleAnimation
                     Storyboard.TargetName ="main"  
                    Storyboard.TargetProperty ="Opacity"  
                    From ="0"  To ="0.8"  Duration ="0:0:0.15" />
                 </ Storyboard >
             </ BeginStoryboard >
         </ EventTrigger >
     </ Window.Triggers >
     < Window.Resources >
     </ Window.Resources >

     < Border  Background ="#F03A3A3A"  Opacity ="1"  CornerRadius ="3" >
             < Canvas >
                
             < Border  Canvas.Top ="0"  Height ="25"  Width =" {Binding ElementName=main, Path=Width,UpdateSourceTrigger=PropertyChanged} "  
                    BorderThickness ="0,0,0,1"  BorderBrush ="#FFEFE2E2" >
                 < TextBlock  x:Name ="lblTitle"  Text ="test"  HorizontalAlignment ="Left"  
                           Foreground ="#FFCBBEBE"  FontSize ="14"
                           VerticalAlignment ="Center"  Margin ="5" />
             </ Border >
             < TextBlock  x:Name ="lblMsg"
                       Foreground ="White"  FontSize ="14"  
                       TextWrapping ="Wrap"  Text ="test"
                       HorizontalAlignment ="Center"  Canvas.Left ="20"
                       Canvas.Top ="50"  
                        />
             < Border  BorderBrush ="#FF60C1C1"  BorderThickness ="0.5"  Height ="22"  
                    Canvas.Bottom ="10"  Canvas.Right ="85"  MouseLeftButtonDown ="Yes_MouseLeftButtonDown"
                 Name ="border1"  Width ="49"  Background ="#FFC7C7C7"  CornerRadius ="2" >
                 < TextBlock  Text ="YES"   HorizontalAlignment ="Center"  VerticalAlignment ="Center" />
             </ Border >
             < Border  BorderBrush ="#FF60C1C1"  BorderThickness ="0.5"  Height ="22"  
                    Canvas.Bottom ="10"  Canvas.Right ="30"  MouseLeftButtonDown ="No_MouseLeftButtonDown"
                Name ="border2"  Width ="49"  CornerRadius ="2"  Background ="#FFC7C7D1" >
                 < TextBlock  Text ="NO"   HorizontalAlignment ="Center"  VerticalAlignment ="Center" />
             </ Border >
         </ Canvas >
     </ Border >
</ Window >
