I have an ASP.NET 1.1 application that will have a large-ish number of users completing a series of educational modules. At the end of each module the user completes a multiple choice test.
I'm trying to figure out what the best way is to display which users completed which module tests. I thought that a DataGrid would work relatively well by having a list of users down the left side of the DG, and the names of the modules across the top. If User "Smith" completed module test "VAP", then the DataGrid cell at that "coordinate" would be filled with a solid colour. Any module tests not completed would remain empty.
My question (after all of that), is how can orient the names of the modules across the top of the DG (i.e. the headers) vertically (or at an angle), in order to use space as effeciently as possible?
