Data Widgets is a classic product and is old technology, about 12 years old. If the customer wanted a COM Grid they should have purchased NetAdvantage, as it includes UltraGrid, which was the next generation Grid after Data Widgets and with the NetAdvantage you receive three Grids (COM,ASP.Net and Windows Forms), so once you learn the COM Grid the object model is the same for the ASP.NET and Windows Forms Grids and you already have these Grids for when you are ready to move to Microsoft Visual Studio .Net, this applies throughout the NetAdvantage, as it includes over 100 Components.
