As I was posting my message about using Sparse in grids, I realized that I also don't quite understand the rules regarding the use of CurrentControl and DynamicCurrentControl. For example, if you use DynamicCurrentControl for a column, does CurrentControl then have no function in that column? In other words, does DynamicCurrentControl always override CurrentControl whenever DynamicCurrentControl is set?
Does CurrentControl change to whatever DynamicCurrentControl currently is, or is CurrentControl a static value that always applies to the entire column?
