房租管理小软件（七）：flowlayoutPancel 中增加分类控

见下图的

                string FNodeName = dt.Rows[i]["FNodeName"].ToString();
                if (i == 0)
                {
                    RoomControl.Thumbnail.GroupItem gItem = new GroupItem();
                    gItem.Size = new Size(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width-70, gItem.Size.Height);//需要把分类的迟寸设成，
                   
                    gItem.labelControl1.Text = FNodeName;
                    //v.Take(1).Single().
                    this.thumbnailFlowLayoutPanel1.Controls.Add(gItem);
                    this.thumbnailFlowLayoutPanel1.SetFlowBreak(gItem, true);
                }
