I just wonder if LightSwitch provides anyway to customize a way Business Custom type could be sorted. For example, I have an academic term business type which extends from string. The correct format is YYYYX, while X is either F (Fall),
S (Spring), or U (Summer). For example, the sorting order should be 2007S, 2007U, 2007F, and 2008S. However, if you sort them in LightSwitch grid, you will have 2007F before 2007S and 2007U instead.
I think I could also create a custom control grid to take care of the custom sorting, but it would be great if this could be done when you define a Business Custom Type as well.
