若要运行此代码示例,请将其粘贴到包含类型的实例的项目DataGridView名为DataGridView1To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然后,确保事件处理程序相关联RowHeightInfoPushed事件。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

引发此事件时VirtualMode属性设置为trueDataSource属性设置为值nullThis event is raised when the VirtualMode property is set to true or the DataSource property is set to a value other than null. 使用此事件来跟踪和存储,以便它可以还原在排序操作之后的行的高度信息。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,才会发生此事件。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,必须存储在同一时间的新高度信息。If you change the height of a row programmatically, you must store the new height information at the same time.
