DataGridView.ColumnHeadersDefaultCellStyleChanged 事件

定义

ColumnHeadersDefaultCellStyle 属性的值更改时发生。Occurs when the value of the ColumnHeadersDefaultCellStyle property changes.

public:
 event EventHandler ^ ColumnHeadersDefaultCellStyleChanged;
public event EventHandler ColumnHeadersDefaultCellStyleChanged;
member this.ColumnHeadersDefaultCellStyleChanged : EventHandler 
Public Custom Event ColumnHeadersDefaultCellStyleChanged As EventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中,事件处理程序报告 @no__t 的事件发生。In the example, an event handler reports on the occurrence of the ColumnHeadersDefaultCellStyleChanged event. 此报表可帮助你了解何时发生事件,并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件,请考虑将 @no__t 0 替换为 Console.WriteLine,或将消息附加到多行 TextBoxTo report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行示例代码,请将其粘贴到包含名为 @no__t DataGridView 类型实例的项目中。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然后,确保事件处理程序与 @no__t 0 事件关联。Then ensure that the event handler is associated with the ColumnHeadersDefaultCellStyleChanged event.

private void DataGridView1_ColumnHeadersDefaultCellStyleChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the DataGridView.ColumnHeadersDefaultCellStyleChanged event.");

}
Private Sub DataGridView1_ColumnHeadersDefaultCellStyleChanged(sender as Object, e as EventArgs) _ 
     Handles DataGridView1.ColumnHeadersDefaultCellStyleChanged

   MessageBox.Show("You are in the DataGridView.ColumnHeadersDefaultCellStyleChanged event.")

End Sub

注解

ColumnHeadersDefaultCellStyle 属性返回的 @no__t 的任何属性设置为新值或将 ColumnHeadersDefaultCellStyle 属性设置为新的 DataGridViewCellStyle,但至少有一个属性值与上一个单元格样式对象不同时,将发生此事件。This event occurs when any properties of the DataGridViewCellStyle returned by the ColumnHeadersDefaultCellStyle property is set to a new value or when the ColumnHeadersDefaultCellStyle property is set to a new DataGridViewCellStyle with at least one property value different than the previous cell style object.
