變化的datagridview cellstyle邊框顏色

Question

我想基於細胞

此背景顏色更改單元格邊框的顏色是什麼，我已經使用

'Draw custom cell borders. 
     Using Brush As New SolidBrush(grdList.ColumnHeadersDefaultCellStyle.BackColor) 
      e.Graphics.FillRectangle(Brush, e.CellBounds) 
     End Using 

     e.Paint(e.CellBounds, DataGridViewPaintParts.All And Not DataGridViewPaintParts.ContentBackground) 
     Debug.Print(e.CellStyle.BackColor.ToString) 
     ControlPaint.DrawBorder(e.Graphics, e.CellBounds, e.CellStyle.BackColor, 1, _ 
           ButtonBorderStyle.Solid, e.CellStyle.BackColor, 1, _ 
           ButtonBorderStyle.Solid, e.CellStyle.BackColor, 1, _ 
           ButtonBorderStyle.Solid, Color.Black, 1, _ 
           ButtonBorderStyle.Solid) 

這是結果

我不知道目前看到的白線

正如你可以設置邊框樣式喲沒有一個選項：

Me.DataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None 

然後處理CellPainting事件和油漆邊界：

Private Sub DataGridView1_CellPainting(sender As Object, _ 
    e As DataGridViewCellPaintingEventArgs) Handles DataGridView1.CellPainting 

    If (e.ColumnIndex < 0 OrElse e.RowIndex < 0) Then Return 
    e.Paint(e.CellBounds, DataGridViewPaintParts.All) 
    Dim r = e.CellBounds 
    e.Graphics.DrawLine(Pens.Black, r.Left, r.Top, r.Right, r.Top) 
    e.Graphics.DrawLine(Pens.Black, r.Left, r.Bottom, r.Right, r.Bottom) 
    e.Handled = True 
End Sub
