TextBox 樣式和範本

本主題說明 TextBox 控件項的樣式和範本。 您可以修改預設的 ControlTemplate,為控制項提供唯一的外觀。 如需詳細資訊,請參閱為控制項建立範本

TextBox 組件

下表列出 TextBox 控件項的具名組件。

部分 類型 描述
PART_ContentHost FrameworkElement 可以包含 FrameworkElement 的視覺元素。 TextBox 的文字會顯示在此元素中。

TextBox 狀態

下表列出 TextBox 控制項的視覺物件狀態。

VisualState 名稱 VisualStateGroup 名稱 描述
Normal CommonStates 預設狀態。
MouseOver CommonStates 滑鼠指標移到控制項上。
已停用 CommonStates 已停用控制項。
ReadOnly CommonStates 使用者無法變更 TextBox 中的文字。
焦點 FocusStates 控制項已取得焦點。
未取得焦點 FocusStates 控制項未取得焦點。
有效 ValidationStates 控制項會使用 Validation 類別,且 Validation.HasError 的附加屬性為 false
InvalidFocused ValidationStates Validation.HasError 附加屬性為具有焦點控制項的 true
InvalidUnfocused ValidationStates Validation.HasError 附加屬性為不具有焦點控制項的 true

TextBox ControlTemplate 範例
