注解

Left Right当属性设置为或时, Multiline属性将自动设置为trueAlignmentWhen the Alignment property is set to Left or Right, the Multiline property is automatically set to true.

如果将Appearance属性设置为FlatButtons, 则它仅在Alignment属性设置为Top时才会显示。When you set the Appearance property to FlatButtons, it only appears as such when the Alignment property is set to Top. 否则, 该Appearance属性将显示为, 前提是Buttons设置为值。Otherwise, the Appearance property displays as if set to the Buttons value.

Appearance属性设置为Buttons时, 还必须将Alignment属性设置为Top , 以使按钮正确显示。When you set the Appearance property to Buttons, you must also set the Alignment property to Top so that the buttons display correctly.

备注

Appearance属性设置为Buttons时, 还必须将Alignment属性设置为Top , 以便选项卡页的内容正确显示。When you set the Appearance property to Buttons, you must also set the Alignment property to Top so that the tab page contents display correctly. 此外, 如果启用了视觉样式, 并Alignment将属性设置为以外的值Top, 则选项卡内容可能不会正确呈现。Additionally, when visual styles are enabled, and the Alignment property is set to a value other than Top, the tab contents may not render correctly.
