WPF 自定義樣式
引言
對於WPF開發者而言，默認的控件樣式是不是覺得非常的”Low“或者說不好看。其實我也是一樣，看多了就覺得樣式一般般，不好看。因此如何解決這個問題呢？當然是自己來定義控件的樣式。
本節使用Visual Studio自帶的功能——“編輯模板”來實現只需修改顏色（邊框、背景、前景等）的控件美化功能。

廢話不多說，首先貼上自己定義並使用過的幾個控件的樣式，如下：
Button（按鈕）樣式
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" StrokeDashArray="1 2" SnapsToDevicePixels="true" StrokeThickness="1" Stroke="#FF2C628B"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

由於篇幅有限我就只做這麼幾個的演示了。
漁
前面我只是拋磚引玉的介紹了幾個控件的樣式，下面我就簡單的地說明下如何實現上面這些控件的樣式。
上面的控件樣式都是使用VS找到其原始的默認樣式，然後修改其邊框、背景以及前景顏色即可實現了我們自己的控件樣式了。
- 在XAML文件中鍵入我們想要自定義的控件（這裏用Button作爲示例），如下圖所示。
- 找到設計窗口（上圖中左邊的區域叫做設計窗口）上的按鈕，並用鼠標右鍵點擊。
- 然後會彈出以下對話框
- 如果像我一樣只是用來定義全局的按鈕控件樣式的話，就不需要關心Key的名字（ButtonStyle1），反之的話，自己取好名。點擊確定即可。定義位置：生成的樣式或者模板資源存在哪個文件內。
- 我們在當前文檔下找到我們的資源如下所示：
<Page.Resources>
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" StrokeDashArray="1 2" SnapsToDevicePixels="true" StrokeThickness="1" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>
<SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>
<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>
<SolidColorBrush x:Key="Button.Pressed.Background" Color="#FFC4E5F6"/>
<SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/>
<SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/>
<SolidColorBrush x:Key="Button.Disabled.Border" Color="#FFADB2B5"/>
<SolidColorBrush x:Key="Button.Disabled.Foreground" Color="#FF838383"/>
<Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" SnapsToDevicePixels="true">
<ContentPresenter x:Name="contentPresenter" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsDefaulted" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
<Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Page.Resources>
上面是按鈕默認樣式的效果，我們可以根據需求修改成我們自己的樣式了。
值得一提的是上面定義了很多顏色資源，我們只需要去修改其值即可修改樣式。
總結
Visual Studio是一個非常強大的IDE，用好這些工具，你就離理想更進一步了:）
