I usderstand. But my goal is not write special code for assigning of parameters. I'm talking just about case of assigning Datasorce property to TADOQuery. In this case when master dataset scrolls, VCL will automatically substitute parameters in detail dataset IF names of some fields in master dataset are equal to names of parameters. AND You know about that. But the problem of this example is that it will not work in such mode because VCL will assign only first parameter. Can you tell, do your components solve this problem. P.S I use Assess Sincerely yours. Dmitry.
