Examples

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

private void DataGridView1_CellToolTipTextChanged(Object sender, DataGridViewCellEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "CellToolTipTextChanged Event" );
}

Private Sub DataGridView1_CellToolTipTextChanged(sender as Object, e as DataGridViewCellEventArgs) _ 
     Handles DataGridView1.CellToolTipTextChanged

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

End Sub
