Remarks

ToolStripTextBox 是针对在 ToolStrip中进行托管而优化的 TextBoxToolStripTextBox is the TextBox optimized for hosting in a ToolStrip. 寄宿控件的属性和事件的子集在 ToolStripTextBox 级别公开,但基础 TextBox 控件可通过 TextBox 属性完全访问。A subset of the hosted control's properties and events are exposed at the ToolStripTextBox level, but the underlying TextBox control is fully accessible through the TextBox property.

ToolStripTextBox 控件允许用户在应用程序中输入文本。The ToolStripTextBox control allows the user to enter text in an application. 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。This control has additional functionality that is not found in the standard Windows text box control, including multiline editing.

通常,ToolStripTextBox 控件用于显示单行文本,或接受它作为输入。Typically, a ToolStripTextBox control is used to display a single line of text or accept it as input. 您可以使用 Multiline 启用要显示或输入的多个文本行。You can use the Multiline to enable multiple lines of text to be displayed or entered. AcceptsTabAcceptsReturn 属性设置为 true,以允许在多行 ToolStripTextBox 控件中进行更大的文本操作。Set the AcceptsTab and AcceptsReturn properties to true to allow greater text manipulation in a multiline ToolStripTextBox control.

可以通过将 MaxLength 属性设置为特定数量的字符来限制输入 ToolStripTextBox 控件中的文本量。You can limit the amount of text entered into a ToolStripTextBox control by setting the MaxLength property to a specific number of characters. 使用 "CharacterCasing" 属性可允许用户只键入大写、仅小写或将大写和小写字符组合到 ToolStripTextBox 控件中。Use the CharacterCasing property to allow the user to type only uppercase, only lowercase, or a combination of uppercase and lowercase characters into the ToolStripTextBox control.

若要限制在 ToolStripTextBox 控件中输入文本,可以为 KeyDown 事件创建事件处理程序,以便验证在控件中输入的每个字符。To restrict text from being entered in a ToolStripTextBox control, you can create an event handler for the KeyDown event in order to validate each character entered in the control. 还可以通过将 ReadOnly 属性设置为 true,来限制 ToolStripTextBox 控件中的所有数据输入。You can also restrict all entry of data in a ToolStripTextBox control by setting the ReadOnly property to true.
