Hi Sherzod,
thank you for your help.
=> It works when I use forms but unfortunately not when I use frames like I do.
The width property of column "Artikelgruppe" is defned with value 250 but header column of "Artikelgruppe" does not grow.
Is it possible to change the width of "Artikelgruppe"in my coding?
I already found the solution, they can close the Topic.
I just checked the Floating option and to move it over the grid and other controls, I pointed the Draglable to True.
