Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DataSourceChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. Then ensure that the event handler is associated with the DataSourceChanged event.
private void DataGridView1_DataSourceChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the DataGridView.DataSourceChanged event.");
}
Private Sub DataGridView1_DataSourceChanged(sender as Object, e as EventArgs) _
Handles DataGridView1.DataSourceChanged
MessageBox.Show("You are in the DataGridView.DataSourceChanged event.")
End Sub
