示例

下面的代码示例调整 的单元格边框 DataGridView ，以便用双边框将内部单元格和左上角的标题单元格与行标题和列标题分隔开来。 此示例演示如何重写 AdjustColumnHeaderBorderStyle、 AdjustRowHeaderBorderStyle和 AdjustCellBorderStyle 方法和 AdjustedTopLeftHeaderBorderStyle 属性。 这些成员使用 DataGridViewAdvancedBorderStyle 对象来修改单个单元格边框。

注解

控件 DataGridView 允许你完全自定义其外观，包括单元格和标题的边框。 具有 DataGridViewCellBorderStyle、 ColumnHeadersBorderStyle和 RowHeadersBorderStyle 属性，可用于设置单元格边框的外观。 但是，如果需要进一步自定义边框，类 DataGridViewAdvancedBorderStyle 允许您在单元格的各个边设置边框的样式。 的 Left、 Right、 Top和 Bottom 属性 DataGridViewAdvancedBorderStyle 分别表示单元格的左、右、上和下边框。 可以在 的 AdvancedCellBorderStyle、 AdvancedColumnHeadersBorderStyleAdvancedRowHeadersBorderStyle 属性上设置这些属性DataGridView，以便为单元格之间的边框生成各种外观。

构造函数

DataGridViewAdvancedBorderStyle()

初始化 DataGridViewAdvancedBorderStyle 类的新实例。

属性

All	获取或设置单元格所有边框的边框样式。
Bottom	获取或设置单元格下边框的样式。
Left	获取单元格左边框的样式。
Right	获取单元格右边框的样式。
Top	获取单元格上边框的样式。

方法

Equals(Object)	确定指定的对象是否等于当前的 DataGridViewAdvancedBorderStyle。
GetHashCode()	用作特定类型的哈希函数。
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示 DataGridViewAdvancedBorderStyle 的字符串。

显式接口实现

ICloneable.Clone()

创建作为当前实例副本的新对象。
