Esempio

Nell'esempio di codice seguente viene creata un'istanza di DataGridTableStyle e vengono impostate le BackColor proprietà e AlternatingBackColor su nuovi valori. L'esempio richiede che sia presente un oggetto con un DataGrid System.Data.DataSet oggetto contenente alcuni dati e un oggetto Button in un oggetto Form.
