示例

下面的代码示例演示如何使用此类型。The following code example demonstrates the use of this type. 在示例中,事件处理程序报告的匹配项RowHeightInfoNeeded事件。In the example, an event handler reports on the occurrence of the RowHeightInfoNeeded event. 此报告可帮助您了解事件发生的并可以帮助您进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告或频繁发生的事件上多个事件,请考虑更换ShowConsole.WriteLine或将消息附加到多行TextBoxTo report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.

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RowHeightInfoNeeded事件。Then ensure that the event handler is associated with the RowHeightInfoNeeded event.

private void DataGridView1_RowHeightInfoNeeded(Object sender, DataGridViewRowHeightInfoNeededEventArgs 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();
MessageBox.Show(messageBoxCS.ToString(), "RowHeightInfoNeeded Event" );
}
Private Sub DataGridView1_RowHeightInfoNeeded(sender as Object, e as DataGridViewRowHeightInfoNeededEventArgs) _ 
     Handles DataGridView1.RowHeightInfoNeeded

    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()
    MessageBox.Show(messageBoxVB.ToString(),"RowHeightInfoNeeded Event")

End Sub
