注解

ToolStripTextBox 是为在 TextBox 中承载而优化的 ToolStrip。 所承载控件的属性和事件的子集在 ToolStripTextBox 级别进行公开，但基础 TextBox 控件可通过 TextBox 属性进行完全访问。

控件 ToolStripTextBox 允许用户在应用程序中输入文本。 此控件具有在标准 Windows 文本框控件中找不到的其他功能，包括多行编辑。

通常， ToolStripTextBox 控件用于显示单行文本或接受它作为输入。 可以使用 Multiline 来启用要显示或输入的多行文本。 将 AcceptsTab 和 AcceptsReturn 属性设置为 以 true 允许在多行 ToolStripTextBox 控件中更好地操作文本。

可以通过将 属性设置为MaxLength特定数量的字符来限制在ToolStripTextBox控件中输入的文本量。 CharacterCasing使用 属性允许用户在 控件中仅键入大写字母、小写字符或大写字符和小写字符ToolStripTextBox的组合。

若要限制在控件中 ToolStripTextBox 输入文本，可以为事件创建事件处理程序 KeyDown ，以验证在控件中输入的每个字符。 还可以通过将 属性设置为 ReadOnlytrue来限制控件中的所有ToolStripTextBox数据输入。
