主题：如何做到窗口中的表同时显示行号及复选框

 你照抄看效果就对了。

Public Sub OwnerDrawCell(ByVal sender As Object, ByVal e As C1.Win.C1FlexGrid.OwnerDrawCellEventArgs)
If e.Row >= sender.Rows.Fixed And e.Col = sender.Cols.Fixed - 1 Then
    Dim rowNumber As Integer = e.Row - sender.Rows.Fixed + 1
    e.Text = rowNumber.ToString()
    e.Style.ForeColor = Color.SteelBlue
    e.Style.TextAlign = C1.Win.C1FlexGrid.TextAlignEnum.CenterCenter
End If
If e.Row = 0 Then
    e.Style.ForeColor = Color.Black
End If
End Sub
