TextBox ControlTemplate 範例

更新：2007 年 11 月

Windows Presentation Foundation (WPF) 中的控制項具有 ControlTemplate，其中包含該控制項的視覺化樹狀結構。您可以透過修改控制項的 ControlTemplate，變更該控制項的結構和外觀。您無法只取代控制項的視覺化樹狀結構的某一部分；若要變更控制項的視覺化樹狀結構，您必須將控制項的 Template 屬性設定為完整的新 ControlTemplate。

本主題將說明 WPFTextBox 控制項的 ControlTemplate。

重要事項：
TextBox 的 ControlTemplate 必須剛好包含一個項目，並且標記為內容裝載項目；這個項目將用來呈現 TextBox 的內容。若要將項目標記為內容裝載，請指派給它特殊名稱 PART_ContentHost。內容裝載項目必須是 ScrollViewer 或 AdornerDecorator。內容裝載項目無法裝載任何子項目。

TextBox ControlTemplate 範例

雖然這個範例包含 TextBox 之 ControlTemplate 中預設定義的所有項目，但是您應該將特定值視為範例。
