Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DataGridView.RowErrorTextNeeded 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 DataGridView.RowErrorTextNeeded event.

private void DataGridView1_RowErrorTextNeeded(Object sender, DataGridViewRowErrorTextNeededEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowErrorTextNeeded Event" );
}
Private Sub DataGridView1_RowErrorTextNeeded(sender as Object, e as DataGridViewRowErrorTextNeededEventArgs) _ 
     Handles DataGridView1.RowErrorTextNeeded

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowErrorTextNeeded Event")

End Sub
