DataGridView.RowHeightInfoPushed 事件

定义

用户更改行高度时发生。Occurs when the user changes the height of a row.

public:
 event System::Windows::Forms::DataGridViewRowHeightInfoPushedEventHandler ^ RowHeightInfoPushed;
public event System.Windows.Forms.DataGridViewRowHeightInfoPushedEventHandler RowHeightInfoPushed;
member this.RowHeightInfoPushed : System.Windows.Forms.DataGridViewRowHeightInfoPushedEventHandler 
Public Custom Event RowHeightInfoPushed As DataGridViewRowHeightInfoPushedEventHandler 

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 RowHeightInfoPushed 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 RowHeightInfoPushed event.

private void DataGridView1_RowHeightInfoPushed(Object sender, DataGridViewRowHeightInfoPushedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Height", e.Height );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "MinimumHeight", e.MinimumHeight );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowHeightInfoPushed Event" );
}
Private Sub DataGridView1_RowHeightInfoPushed(sender as Object, e as DataGridViewRowHeightInfoPushedEventArgs) _ 
     Handles DataGridView1.RowHeightInfoPushed

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Height", e.Height)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "MinimumHeight", e.MinimumHeight)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowHeightInfoPushed Event")

End Sub

注解

VirtualMode 属性设置为 trueDataSource 属性设置为 null 以外的值时,将引发此事件。This event is raised when the VirtualMode property is set to true or the DataSource property is set to a value other than null. 此事件用于跟踪和存储行高度信息,以便可以在进行排序操作后还原。This event is used to track and store row height information so that it can be restored after a sorting operation. 若要还原高度信息,请处理 RowHeightInfoNeeded 事件。To restore height information, handle the RowHeightInfoNeeded event. 请注意,仅当用户更改行的高度时,才发生此事件。Note that this event occurs only when the user changes the height of a row. 如果以编程方式更改行的高度,则必须同时存储新的高度信息。If you change the height of a row programmatically, you must store the new height information at the same time.
