I'm a big fan of Linq, and use it a lot because I like its ability to code against in a natural c# kind of way. One thing I don't like, however, and maybe this is just me being thick or stupid, but I haven't found a way to specify it as the data-source at design time for the purpose of customizing my column appearances etc. Anybody else tackled this with more success than myself? I found I could specify the linq to sql class in "add Project Data Source" (in the context menu for the grid), but this resulted in a grid based on the internal class metadata, not the table columns. Thx, Bob Graham
