Alternative of DataWindow in C#

Question

Im working on an application which was build by PowerBuilder 0.7, later this Application is migrated to PowerBuilder 11.5
as knowen science PowerBuilder 10.5 we can build .Net Targets
Now my company has two choises
1- Migrate the application to PowerBuilder 12 on which you can enjoy the benfits of .Net Framework 0.4 and you can enjoy the world of .Net
2- Completely remove our application to .Net world
i prefere the second chiose specially we think to make our application on the web  but as first step we will begin with the reports of our application
the only problem with the second choice is that our application depends hundred percent on agreate control called DataWindow and i know that there is DataWindow .Net control
but as we target to make our applicaton on the web we donot want to depend on DataWindow any more so my question
is .Which choice do you prefere ?
is there an alternativ of Datawindow in .Net?
Thanks
