示例

下面的代码示例演示如何在主要用于显示的DataGridView控件中使用此属性。The following code example illustrates the use of this property in a DataGridView control intended primarily for display. 在此示例中, 控件的可视外观是通过多种方式自定义的, 并且控件配置为具有有限的交互功能。In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. 此示例是DataGridViewCellStyle类概述中提供的一个更大示例的一部分。This example is part of a larger example available in the DataGridViewCellStyle class overview.

注解

控件使用 cells InheritedStyle属性指示的样式显示单元格, 该样式继承类型DataGridViewCellStyle的其他属性的样式。 DataGridViewThe DataGridView control displays its cells using the styles indicated by the cell InheritedStyle property, which inherits styles from other properties of type DataGridViewCellStyle. 通过DefaultCellStyle属性指定的样式将影响所有单元, 但当由通过以下属性指定的样式重写时除外:The styles specified through the DefaultCellStyle property affect all cells except when overridden by the styles specified through the following properties:

有关详细信息, 请参阅Windows 窗体 DataGridView 控件中的单元格样式For more information, see Cell Styles in the Windows Forms DataGridView Control.

获取此属性时, 如果DataGridViewCellStyle尚未访问属性, 将创建具有默认值的。When getting this property, a DataGridViewCellStyle with default values will be created if the property has not already been accessed. 在为多个行获取此属性时, 这可能会影响性能。This can cause a performance impact when getting this property for many rows. 请尽可能使用 single DataGridViewCellStyle为多行设置此属性。Whenever possible, use a single DataGridViewCellStyle to set this property for multiple rows. 有关详细信息,请参阅 缩放 Windows 窗体 DataGridView 控件的最佳做法For more information, see Best Practices for Scaling the Windows Forms DataGridView Control.
