備註

類別 DataGridViewColumn 代表 控制項中的 DataGridView 邏輯資料行。 您可以透過 Columns 控制項的集合擷取資料行。

DataGridViewRow不同于 包含 中 DataGridViewDataGridViewColumn 實際儲存格集合的 ，主要用來調整資料行使用者介面的外觀和行為， (UI) ，例如欄寬和儲存格樣式。 如需儲存格樣式的詳細資訊，請參閱dataGridView 控制項中的Windows Forms儲存格樣式。

衍生自 DataGridViewColumn 的類型通常會將 屬性初始化 CellTemplate 為衍生自 DataGridViewCell 類別之相關型別的新實例。 與個別儲存格外觀或行為相關的任何資料行屬性，都是樣板儲存格之對應屬性的包裝函式。 變更資料行上的其中一個屬性，會自動變更資料格範本和資料行中所有儲存格上的值。 若要覆寫個別儲存格的指定值，請在設定資料行值之後設定儲存格值。

給繼承者的注意事項

當您衍生自 DataGridViewColumn 並將新屬性新增至衍生類別時，請務必覆寫 Clone() 方法，以在複製作業期間複製新屬性。 您也應該呼叫基類的 Clone() 方法，以便基類的屬性複製到新的儲存格。
