示例

下面的代码示例演示如何在主要用于显示的 @no__t 0 控件中使用此属性。The following code example illustrates how to use 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. 此示例摘自 DataGridViewCellStyle 类概述中提供的一个更大的示例。This example is part of a larger example available in the DataGridViewCellStyle class overview.

注解

如果将此属性设置为自动调整大小模式,则用户无法调整行标题的宽度。When this property is set to an automatic sizing mode, the width of the row headers cannot be adjusted by the user.

若要以编程方式调整行标题的高度,请使用 @no__t 的方法或设置 @no__t 的属性。To adjust the height of the row headers programmatically, use the AutoResizeRowHeadersWidth method or set the RowHeadersWidth property.

若要设置列标题的大小调整模式,请使用 ColumnHeadersHeightSizeMode 属性。To set the sizing mode for the column headers, use the ColumnHeadersHeightSizeMode property.

有关标头大小的详细信息,请参阅Windows 窗体 DataGridView 控件中的调整大小选项For more information about header sizing, see Sizing Options in the Windows Forms DataGridView Control.

备注

@No__t 0 的控件不支持双缓冲。The DataGridView control does not support double buffering. 如果在派生的 DataGridView 控件中将 DoubleBuffered 设置为 true,则在对行、列或标题进行调整或对列重新排序时,用户不会收到视觉反馈。If DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.
