>I have a grid based on a table where in one column each row in the grid needs a different inputmask (stored in a field in the table). By setting the column sparse to .f. and in the afterrowcolchange issuing a this.column1.inputmask=myalias.fimask it works fine.
>Problem is only sets this up once you move to that column and arrow down each row. Tried doing this on the init programmatically but it gets reset after the init. Any ideas? Really I need a dynamicinputmask property to the column but that doesn't exist.

It now exist in 5.0. Is this the version you are using?
