>>> The first item that gets events here is control in column. I also do not see why column control even need to be subclassed, because evrything you need could be done using control, header and grid class. Column class subclassed causes VFP crash often, as well as it is very hard to maintain and use. Header can be made as class in VCX library, and it can be put into column in design-time.

> Nadya, you understood correctly. I have my own header class in VCX class library. When I making new grid, I put this header into column in design-time and it replaces original default header. In addition, I have simple program that used to run over SCX or VCX file and replace all default header class to new header class, so I do not need to replace headers manually for each column of large grid.

Vlad,

It seems like a great idea. So, once added your originally programatically created class into vcx, you now have ability to even modify this class visually, right? I'm not completely sure, that I can follow all steps here without your further assistance, but we can try. For instance, we can try this procedure for multiselect grid class, which Cetin has here in Files section.

And also you now can copy this class from one classlib to another, right?
