dev控件的格式化

//GridView的单元格
GridColumn gcWeight = DevColumn.CreateColumn("text", GetInfo("Weight"), "WeightSum", 100, 20, true);
gcWeight.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
gcWeight.DisplayFormat.FormatString = "{0:n3}";
gv1.Columns.Add(gcWeight);


//TextEdit
txtWeightSum.Properties.Mask.EditMask = "#######0.0##";
txtWeightSum.Properties.Mask.MaskType = MaskType.Numeric;
txtWeightSum.Properties.Mask.UseMaskAsDisplayFormat = true;
