其中一個 DataGridViewHeaderBorderStyle 值。
- 屬性
例外狀況
設定這個屬性時所指定的值不是有效的 DataGridViewHeaderBorderStyle 值。
設定這個屬性時所指定的值是 Custom。
範例
下列程式碼範例示範如何設定 ColumnHeadersDefaultCellStyle 、 AutoSizeRowsMode 、 ColumnHeadersBorderStyle 、 RowHeadersVisibleCellBorderStyleBackgroundColorSelectionModeGridColorColumnCount 和 MultiSelect 屬性。 此外，程式碼範例會示範如何設定 DataGridViewColumn.Name 和 DataGridViewColumn.DefaultCellStyle 屬性。 若要執行此範例，請將程式碼貼到包含 DataGridView 具名 dataGridView1 的表單中，然後從表單的建構函式或 Load 事件處理常式呼叫 SetUpDataGridView 方法。 確定所有事件都與其事件處理常式相關聯。

備註
ColumnHeadersBorderStyle如果 屬性設定為 以外的 Single 任何專案，則 GridColor 屬性必須是系統色彩。
您無法將這個屬性設定為 Custom 值，這是唯讀值，表示框線樣式已透過屬性使用 AdvancedColumnHeadersBorderStyle 來自訂。
注意
如果透過 Application.EnableVisualStyles 方法為應用程式啟用視覺化樣式，且 EnableHeadersVisualStyles 屬性為 true ，則會使用目前的主題繪製資料行標頭。 在此情況下，除了未套用主題的 ColumnHeadersBorderStyle 之外 TopLeftHeaderCell ，所有資料行標頭都會忽略 屬性的值。
