This class is currently used with the CancelRowEdit and RowDirtyStateNeeded events of the DataGridView control. It allows you to specify a response to events that occur when the control needs the answer to a question. The answer to the question is specified by setting the Response property.
The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the CancelRowEdit 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 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 CancelRowEdit event.
private void DataGridView1_CancelRowEdit(Object sender, QuestionEventArgs e) { System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder(); messageBoxCS.AppendFormat("{0} = {1}", "Response", e.Response ); messageBoxCS.AppendLine(); MessageBox.Show(messageBoxCS.ToString(), "CancelRowEdit Event" ); }
