Check if a new row is added to a DataGridView

I download data from my server and use a DataGridView to present the result. When a new row is added, I’d like my program to show a signal. How can I do that?


Subscribe to the DataGridView.RowsAdded event.

dataGridView1.RowsAdded += new DataGridViewRowsAddedEventHandler(dataGridView1_RowsAdded);

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