DataGridView.ColumnDataPropertyNameChanged 事件

定义

当列的 DataPropertyName 属性值更改时发生。Occurs when the value of the DataPropertyName property for a column changes.

public:
 event System::Windows::Forms::DataGridViewColumnEventHandler ^ ColumnDataPropertyNameChanged;
public event System.Windows.Forms.DataGridViewColumnEventHandler ColumnDataPropertyNameChanged;
member this.ColumnDataPropertyNameChanged : System.Windows.Forms.DataGridViewColumnEventHandler 
Public Custom Event ColumnDataPropertyNameChanged As DataGridViewColumnEventHandler 

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 ColumnDataPropertyNameChanged 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 ColumnDataPropertyNameChanged event.

private void DataGridView1_ColumnDataPropertyNameChanged(Object sender, DataGridViewColumnEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnDataPropertyNameChanged Event" );
}
Private Sub DataGridView1_ColumnDataPropertyNameChanged(sender as Object, e as DataGridViewColumnEventArgs) _ 
     Handles DataGridView1.ColumnDataPropertyNameChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Column", e.Column)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ColumnDataPropertyNameChanged Event")

End Sub
