Hi Rolandas.

>> My problem is - how describe function without form designer? <<

You mean that you have defined your grid class in code instead of visually? If this is the case, You code the method just as you would any procedure.

In the prg, after you define your grid class like so:

DEFINE CLASS MyGrid AS Grid

You add the line:

FUNCTION AfterRowColChange

Your code here...

ENDFUNC
