| PART_TextBox | DatePickerTextBox | 允许输入日期的文本框。 |
| PART_Popup | Popup | DatePicker 控件的弹出窗口。 |
DatePicker 状态
下表列出了 DatePicker 控件的可视状态。
| VisualState 名称 | VisualStateGroup 名称 | 说明 |
|---|---|---|
| 普通 | CommonStates | 默认状态。 |
| 已禁用 | CommonStates | 禁用 DatePicker。 |
| 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。 |
DatePickerTextBox 部件
下表列出了 DatePickerTextBox 控件的已命名部件。
| 组成部分 | 类型 | 描述 |
|---|---|---|
| PART_Watermark | ContentControl | DatePicker 中包含初始文本的元素。 |
| PART_ContentElement | FrameworkElement | 可包含 FrameworkElement 的视觉对象元素。 TextBox 的文本显示在此元素中。 |
DatePickerTextBox 状态
下表列出了 DatePickerTextBox 控件的可视状态。
| VisualState 名称 | VisualStateGroup 名称 | 说明 |
|---|---|---|
| 普通 | CommonStates | 默认状态。 |
| 已禁用 | CommonStates | 禁用 DatePickerTextBox。 |
| MouseOver | CommonStates | 鼠标指针悬停在 DatePickerTextBox 上方。 |
| ReadOnly | CommonStates | 用户不能更改 DatePickerTextBox 中的文本。 |
| Focused | FocusStates | 控件有焦点。 |
| 失去焦点 | FocusStates | 控件没有焦点。 |
| 已打水印 | WatermarkStates | 控件显示其初始文本。 DatePickerTextBox 处于用户未输入文本或未选择日期的状态。 |
| 无水印 | WatermarkStates | 用户在 DatePickerTextBox 中输入了文本或在 DatePicker 中选择了一个日期。 |
| 有效 | ValidationStates | 该控件使用 Validation 类，Validation.HasError 附加属性为 false。 |
| InvalidFocused | ValidationStates | Validation.HasError 附加属性为 true，控件具有焦点。 |
| InvalidUnfocused | ValidationStates | Validation.HasError 附加属性为 true，控件不具有焦点。 |
DatePicker ControlTemplate 示例
以下示例演示如何定义 DatePicker 控件的 ControlTemplate。
<!--In this example, an implecit style for Calendar is defined elsewhere
in the application. DatePickerCalendarStyle is based on the implicit
style so that the DatePicker will use the application's calendar style.-->
<Style x:Key="DatePickerCalendarStyle"
TargetType="{x:Type Calendar}"
BasedOn="{StaticResource {x:Type Calendar}}" />
<!--The template for the button that displays the calendar.-->
<Style x:Key="DropDownButtonStyle"
TargetType="Button">
<Setter Property="Template">
