Thanks so much for helping I have found your help complicated that findcontrol do not work at delphi prism or i dont know how to use it.
I applied but i see that my gridview do not have itemtemplate it has emptydatatemplate and i cant make it visible. I used to do this very easy way but i have a fire accident and i lost all my external hdd backups and all samples that i cant remember again. I want to attach a session to use at where clause at another datasource. I did try to use your code but didnt succeed Cheers
