參數

dataGridViewAdvancedBorderStyleInput
DataGridViewAdvancedBorderStyle

DataGridViewAdvancedBorderStyle，表示要修改的資料列行首框線樣式。

dataGridViewAdvancedBorderStylePlaceholder
DataGridViewAdvancedBorderStyle

DataGridViewAdvancedBorderStyle，用來儲存對資料列行首框線樣式所做的中繼變更。

singleVerticalBorderAdded
Boolean

true 表示要在所產生的結果上加入單垂直框線，否則為 false。

singleHorizontalBorderAdded
Boolean

true 表示要在所產生的結果上加入單水平框線，否則為 false。

isFirstDisplayedRow

範例

下列程式碼範例示範如何覆寫 AdjustRowHeaderBorderStyle 方法來自訂資料列標題儲存格的框線。 此程式碼範例是提供給 類別之較大範例的 DataGridViewAdvancedBorderStyle 一部分。

public override DataGridViewAdvancedBorderStyle AdjustRowHeaderBorderStyle(
    DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStyleInput,
    DataGridViewAdvancedBorderStyle dataGridViewAdvancedBorderStylePlaceHolder,
    bool singleVerticalBorderAdded,
    bool singleHorizontalBorderAdded,
    bool isFirstDisplayedRow,
    bool isLastDisplayedRow)
{
    // Customize the top border of the first row header and the
    // right border of all the row headers. Use the input style for 
    // all other borders.
    dataGridViewAdvancedBorderStylePlaceHolder.Top = isFirstDisplayedRow ?
        DataGridViewAdvancedCellBorderStyle.InsetDouble :
        DataGridViewAdvancedCellBorderStyle.None;
    dataGridViewAdvancedBorderStylePlaceHolder.Right =
        DataGridViewAdvancedCellBorderStyle.OutsetDouble;

    dataGridViewAdvancedBorderStylePlaceHolder.Left =
        dataGridViewAdvancedBorderStyleInput.Left;
    dataGridViewAdvancedBorderStylePlaceHolder.Bottom =
        dataGridViewAdvancedBorderStyleInput.Bottom;

    return dataGridViewAdvancedBorderStylePlaceHolder;
}

    Public Overrides Function AdjustRowHeaderBorderStyle( _
        ByVal dataGridViewAdvancedBorderStyleInput As DataGridViewAdvancedBorderStyle, _
        ByVal dataGridViewAdvancedBorderStylePlaceHolder As DataGridViewAdvancedBorderStyle, _
        ByVal singleVerticalBorderAdded As Boolean, _
        ByVal singleHorizontalBorderAdded As Boolean, _
        ByVal isFirstDisplayedRow As Boolean, _
        ByVal isLastDisplayedRow As Boolean) As DataGridViewAdvancedBorderStyle

        ' Customize the top border of the first row header and the
        ' right border of all the row headers. Use the input style for 
        ' all other borders.
        If isFirstDisplayedRow Then
            dataGridViewAdvancedBorderStylePlaceHolder.Top = _
                DataGridViewAdvancedCellBorderStyle.InsetDouble
        Else
            dataGridViewAdvancedBorderStylePlaceHolder.Top = _
                DataGridViewAdvancedCellBorderStyle.None
        End If

        With dataGridViewAdvancedBorderStylePlaceHolder
            .Right = DataGridViewAdvancedCellBorderStyle.OutsetDouble
            .Left = dataGridViewAdvancedBorderStyleInput.Left
            .Bottom = dataGridViewAdvancedBorderStyleInput.Bottom
        End With

        Return dataGridViewAdvancedBorderStylePlaceHolder
    End Function
End Class

備註

控制項 DataGridView 會在內部呼叫 AdjustRowHeaderBorderStyle 方法，以判斷資料列標題儲存格的框線外觀。 控制項 DataGridView 通常會使用 dataGridViewAdvancedBorderStyleInput 參數的 AdvancedRowHeadersBorderStyle 屬性值。

給繼承者的注意事項

如果您想要自訂資料列標題儲存格框線的外觀，請覆寫這個方法。
