示例

下面ColumnHeadersDefaultCellStyle的代码示例演示如何设置GridColor CellBorderStyle ColumnHeadersBorderStyleAutoSizeRowsMode、、、、 BackgroundColor RowHeadersVisible、、、和MultiSelect属性。 SelectionMode ColumnCountThe following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. 此外,该代码示例还演示如何设置DataGridViewColumn.NameDataGridViewColumn.DefaultCellStyle属性。In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. 若要运行此示例,请将代码DataGridView粘贴到包含名为dataGridView1的的窗体中SetUpDataGridView ,然后从窗体的构造函数Load或事件处理程序调用方法。To run this example, paste the code into a form that contains a DataGridView nameddataGridView1, and then call the SetUpDataGridView method from the form's constructor or Load event handler. 确保所有事件都与事件处理程序相关联。Ensure all events are associated with their event handlers.

注解

如果将Single GridColor属性设置为以外的任何内容,则属性必须是系统颜色。 ColumnHeadersBorderStyleIf the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

不能将此属性设置为Custom值,这是一个只读值,指示边框样式已通过使用AdvancedColumnHeadersBorderStyle属性进行自定义。You cannot set this property to the Custom value, which is a read-only value indicating that the border style has been customized through the use of the AdvancedColumnHeadersBorderStyle property.

备注

如果通过Application.EnableVisualStyles方法为应用程序启用了视觉样式, EnableHeadersVisualStyles并且属性为true,则使用当前主题绘制列标题。If visual styles are enabled for the application through the Application.EnableVisualStyles method and the EnableHeadersVisualStyles property is true, the column headers are painted using the current theme. 在这种情况下,将忽略ColumnHeadersBorderStyle不应用主题的所有列标题TopLeftHeaderCell的属性值。In this case, the value of the ColumnHeadersBorderStyle property is ignored for all column headers except the TopLeftHeaderCell, to which the theme is not applied.
