项目中，有时会需要无边框的Button，如果没有特别的其他功能需要，我们可以更简单的实现这一点：
<Button Content="myButton" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}"/>
当然，上面的按钮类似于ToolBar风格，移动到上面是蓝色背景。
如果想进一步简单修改，可以用以下方法，实现移动到按钮上出现阴影，按下时内容缩小的功能：
<Button Command="{Binding RefreshSQLCmd}" ToolTip="{DynamicResource Refresh}" SnapsToDevicePixels="True" Background="Transparent" Height="30" Width="30" BorderBrush="Transparent">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Rectangle Height="30" Width="30">
<Rectangle.Fill>
<ImageBrush ImageSource="Images/refresh.ico"></ImageBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" Content="{TemplateBinding Content}"></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Image.Effect">
<Setter.Value>
<DropShadowEffect BlurRadius="20" ShadowDepth="2" Color="#FF446FCB" Opacity="0.8"/>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="RenderTransform">
<Setter.Value>
<ScaleTransform ScaleX="0.95" ScaleY="0.95"/>
</Setter.Value>
</Setter>
<Setter Property="RenderTransformOrigin" Value=".5,.5"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
使用图片作为按钮外观时，如果需要IsEnable为false时变灰，可以通过自定义如下：
<Style x:Key="myButton1" TargetType="Button">
<Style.Resources>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" Value="0.5" />
</Trigger>
</Style.Triggers>
</Style>
</Style.Resources>
</Style>
如果想更复杂的，如下面的圆形按钮，界面上的Button只需要Style绑定就可以了：
<Style x:Key="ButtonStyle1" TargetType="Button">
<Setter Property="Foreground" Value="Black"/>
