检查是否有新行添加到DataGridView

Question

我从服务器下载数据并使用DataGridView来显示结果。当添加新行时，我希望我的程序显示信号。我怎么能这样做？

Answer 1

订阅DataGridView.RowsAdded活动。

dataGridView1.RowsAdded += new DataGridViewRowsAddedEventHandler(dataGridView1_RowsAdded);

void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
    // show the signal
}

Answer 2

您需要使用userAddedRow事件，当激活该事件时，您可以使用它来发送 布尔值，如本例一样，为true或false

 private void usersDGV_UserAddedRow(object sender, DataGridViewRowEventArgs e)
  {
     //this event occurs when user added new row to the datagridview 
     //and will turn the boolean newRowAdded on.
           newRowAdded = true;
  }
