I am trying out now. I have built a class based on a countainer, added 3 labels and an assign-function for a custom property.
Then I in the code of my testform I start with:

SET CLASSLIB TO d:\foxprogs\foxbib\foxbibclass additive
cML = CREATEOBJECT("mltext")
thisform.grdstd1.RowHeight = cML.height
thisform.grdstd1.column1.AddObject("cML","MLText")
thisform.grdstd1.column1.CurrentControl = "cML"

But where do I now assign the value to my custom-property? I tried it in the afterrowcolchange-event of the grid but this fails

TIA
