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 named dataGridView1, 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

此属性DataGridViewCellStyle返回的默认值具有以下初始属性值:The default DataGridViewCellStyle returned by this property has the following initial property values:

DataGridViewCellStyle 属性DataGridViewCellStyle property 默认值Default value
BackColor SystemBrushes.Control 属性的值。The value of the SystemBrushes.Control property.
ForeColor SystemBrushes.WindowText 属性的值。The value of the SystemBrushes.WindowText property.
SelectionBackColor SystemBrushes.Highlight 属性的值。The value of the SystemBrushes.Highlight property.
SelectionForeColor SystemBrushes.HighlightText 属性的值。The value of the SystemBrushes.HighlightText property.
Font Font 属性的值。The value of the Font property.
Alignment DataGridViewContentAlignment.MiddleLeft
WrapMode DataGridViewTriState.True

这些值自动覆盖通过DefaultCellStyle属性设置的值。These values automatically override the values set through the DefaultCellStyle property. 若要强制列标题继承这些DefaultCellStyle值, 则必须将ColumnHeadersDefaultCellStyle对象中的值设置为为DataGridViewCellStyle类指定的默认值。To force column headers to inherit the DefaultCellStyle values, you must set the values in the ColumnHeadersDefaultCellStyle object to the default values indicated for the DataGridViewCellStyle class.

有关单元样式继承的详细信息, 请参阅Windows 窗体 DataGridView 控件中的单元格样式For more information about cell style inheritance, see Cell Styles in the Windows Forms DataGridView Control.

如果视觉样式已启用并且EnableHeadersVisualStyles设置为true, 则除之外的TopLeftHeaderCell所有标题单元均使用当前主题进行绘制, ColumnHeadersDefaultCellStyle并且这些值将被忽略。If visual styles are enabled and EnableHeadersVisualStyles is set to true, all header cells except the TopLeftHeaderCell are painted using the current theme and the ColumnHeadersDefaultCellStyle values are ignored.
