通过

HttpCapabilitiesBase.HidesRightAlignedMultiselectScrollbars 属性

  • 参考

定义

命名空间:
System.Web.Configuration
程序集:
System.Web.dll

获取一个值，该值指示在呈现时是否遮蔽 align 特性值为 right 的 HTML <select multiple> 元素的滚动条。

public:
 virtual property bool HidesRightAlignedMultiselectScrollbars { bool get(); };
public virtual bool HidesRightAlignedMultiselectScrollbars { get; }
member this.HidesRightAlignedMultiselectScrollbars : bool
Public Overridable ReadOnly Property HidesRightAlignedMultiselectScrollbars As Boolean

属性值

Boolean

如果在呈现时遮蔽 true 特性值为 <select multiple> 的 HTML align 元素的滚动条，则为 right；否则为 false。 默认值为 false。

示例

下面的代码示例演示如何确定浏览器是否遮挡右对齐多选元素的滚动条。
