Evento DataGridView.CellToolTipTextChanged

 

Data di pubblicazione: ottobre 2016

Si verifica quando cambia il valore della proprietà ToolTipText di una cella in DataGridView.

Spazio dei nomi:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event DataGridViewCellEventHandler CellToolTipTextChanged

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the E:System.Windows.Forms.DataGridView.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 Overload:System.Windows.Forms.MessageBox.Show with Overload:System.Console.WriteLine or appending the message to a multiline T:System.Windows.Forms.TextBox.

To run the example code, paste it into a project that contains an instance of type T:System.Windows.Forms.DataGridView named DataGridView1. Then ensure that the event handler is associated with the E:System.Windows.Forms.DataGridView.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" );
}
