DataGridView重绘问题

Question

datagridview重绘

Answer 1

昨天试了一晚上oncellpaiting和onpaint 画不出来,今天在尝试OnRowPostPaint
版主能否给点代码借鉴下...

Answer 2

在oncellpaiting将单元格背景色和边框线绘制好了,为什么选中行的背景色设置无效,前景色却有效,求大神解释下...

Answer 3

  Protected Overrides Sub OnCellPainting(ByVal e As DataGridViewCellPaintingEventArgs)
        MyBase.OnCellPainting(e)
        AlternatingRowsDefaultCellStyle.BackColor = Color.AliceBlue
        Dim r As Rectangle = e.CellBounds
        Dim p As Pen = New Pen(Color.SkyBlue, 2)
        r.Offset(New Point(0, 0))
        If (e.RowIndex = -1) Then
            e.CellStyle.BackColor = Color.AliceBlue
            e.CellStyle.Font = New Drawing.Font(e.CellStyle.Font, FontStyle.Bold)
        End If
        Using b As Drawing2D.LinearGradientBrush = New Drawing2D.LinearGradientBrush(e.CellBounds, e.CellStyle.BackColor, e.CellStyle.BackColor, 1, True)
            e.Graphics.FillRectangle(b, e.CellBounds)
        End Using
e.CellStyle.SelectionBackColor = Color.Color.Red
        e.CellStyle.SelectionForeColor = Color.FromArgb(10, 50, 205, 50)
        e.Graphics.DrawRectangle(p, r)
        e.Graphics.DrawRectangle(p, r)
        e.PaintContent(e.ClipBounds)
        e.Handled = True
    End Sub重绘代码,麻烦高手看下为什么e.CellStyle.SelectionBackColor = Color.Red没有效果
