  • 将属性放置在窗体 Property-SubpropertyGridView 控件的开始标记中,其中 SubpropertyTableItemStyle 对象的一个属性(例如 HeaderStyle-ForeColor)。Place an attribute in the opening tag of the GridView control in the form Property-Subproperty, where Subproperty is a property of the TableItemStyle object (for example, HeaderStyle-ForeColor).

  • GridView 控件的开始标记和结束标记之间嵌套 <HeaderStyle> 元素。Nest a <HeaderStyle> element between the opening and closing tags of the GridView control.
