RepeatButton 样式和模板
本主题介绍 RepeatButton 控件的样式和模板。 可以修改默认 ControlTemplate 以赋予控件独特的外观。 有关详细信息，请参阅为控件创建模板。
RepeatButton 部件
RepeatButton 控件没有任何命名部件。
RepeatButton 状态
下表列出了 RepeatButton 控件的可视状态。
| VisualState 名称 | VisualStateGroup 名称 | 说明 |
|---|---|---|
| 普通 | CommonStates | 默认状态。 |
| MouseOver | CommonStates | 鼠标指针悬停在控件上。 |
| Pressed | CommonStates | 已按下控件。 |
| 已禁用 | CommonStates | 已禁用控件。 |
| Focused | FocusStates | 控件有焦点。 |
| 失去焦点 | FocusStates | 控件没有焦点。 |
| 有效 | ValidationStates | 该控件使用 Validation 类，Validation.HasError 附加属性为 false。 |
| InvalidFocused | ValidationStates | 如果控件具有焦点，则 Validation.HasError 附加属性为 true。 |
| InvalidUnfocused | ValidationStates | Validation.HasError 附加属性是让控件不具有焦点的 true。 |
RepeatButton ControlTemplate 示例
以下示例演示如何定义 RepeatButton 控件的 ControlTemplate。

<Setter Property="SnapsToDevicePixels"
Value="True" />
<Setter Property="OverridesDefaultStyle"
Value="true" />

<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RepeatButton}">
<Border x:Name="Border"
