//DataGrid Style
                System.Windows.Forms.DataGridTableStyle tsMain = new DataGridTableStyle();
                this.GridMain.TableStyles.Add(tsMain); //GridMain是DataGrid
                tsMain.MappingName = "manrecord";   // 数据库表名                tsMain.AllowSorting = false;
                tsMain.AlternatingBackColor = System.Drawing.Color.Lavender;
                tsMain.BackColor = System.Drawing.Color.GhostWhite;
                tsMain.ForeColor = System.Drawing.Color.MidnightBlue;
                tsMain.GridLineColor = System.Drawing.Color.RoyalBlue;
                tsMain.HeaderBackColor = System.Drawing.Color.MidnightBlue;
                tsMain.HeaderFont = new System.Drawing.Font("Tahoma", 8F, System.Drawing.FontStyle.Bold);
                tsMain.HeaderForeColor = System.Drawing.Color.Lavender;
                tsMain.LinkColor = System.Drawing.Color.Teal;
