DataGridView.ColumnStateChanged DataGridView.ColumnStateChanged DataGridView.ColumnStateChanged DataGridView.ColumnStateChanged Event

定义

列状态更改(例如获得焦点或失去焦点)时发生。Occurs when a column changes state, such as gaining or losing focus.

public:
 event System::Windows::Forms::DataGridViewColumnStateChangedEventHandler ^ ColumnStateChanged;
public event System.Windows.Forms.DataGridViewColumnStateChangedEventHandler ColumnStateChanged;
member this.ColumnStateChanged : System.Windows.Forms.DataGridViewColumnStateChangedEventHandler 
Public Custom Event ColumnStateChanged As DataGridViewColumnStateChangedEventHandler 

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ColumnStateChanged事件的发生。In the example, an event handler reports on the occurrence of the ColumnStateChanged 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MessageBox.ShowConsole.WriteLine消息替换为多行或将TextBox其追加到多行。To 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DataGridView DataGridView1的类型的实例的项目中。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ColumnStateChanged事件相关联。Then ensure that the event handler is associated with the ColumnStateChanged event.

private void DataGridView1_ColumnStateChanged(Object sender, DataGridViewColumnStateChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "StateChanged", e.StateChanged );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnStateChanged Event" );
}
Private Sub DataGridView1_ColumnStateChanged(sender as Object, e as DataGridViewColumnStateChangedEventArgs) _ 
     Handles DataGridView1.ColumnStateChanged

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

End Sub
