示例

下面的代码示例在虚拟模式下使用 DataGridViewRowsAddedEventHandler 来存储已添加行的事实。 此示例是参考主题中提供的更大示例的 VirtualMode 一部分。

void VirtualConnector::dataGridView1_RowsAdded
    (Object^ sender, DataGridViewRowsAddedEventArgs^ e)
{
    if (newRowNeeded)
    {
        newRowNeeded = false;
        numberOfRows = numberOfRows + 1;
    }
}

private void dataGridView1_RowsAdded(object sender,
     DataGridViewRowsAddedEventArgs e)
{
    if (newRowNeeded)
    {
        newRowNeeded = false;
        numberOfRows = numberOfRows + 1;
    }
}

Private Sub dataGridView1_RowsAdded(ByVal sender As Object, _
    ByVal e As DataGridViewRowsAddedEventArgs) _
    Handles dataGridView1.RowsAdded

    If newRowNeeded Then
        newRowNeeded = False
        numberOfRows = numberOfRows + 1
    End If
End Sub

注解

将 RowsAdded 行添加到 DataGridView 控件时发生 该事件。

创建 DataGridViewRowsAddedEventHandler 委托时，需要标识将处理该事件的方法。 若要将事件与事件处理程序关联，请将该委托的一个实例添加到事件中。 除非移除了该委托，否则每当发生该事件时就会调用事件处理程序。 有关事件处理程序委托的详细信息，请参阅 处理和引发事件。
