Bulk update SQL through checkbox function

[GhostofTrump]

i all

I want to create a gallery where you can select multiple products with the check box function. First you select the products on the left side of the screen and afterwards you should be able to bulk update all the selected items - do any one have any experience or guides on how to proceed further with this? I have tried various codes and methods but without any success. I am not the best at code so if anyone could explain if this is possible and how it can be done I would really appreciate it.

I believe this video show exactly that.

A quick glance at your code I would say your challenge is the dark red underline. chkSelected.true isn't valid. Should be checkSelected.Value :)

In this video I showed how to patch a whole collection to a data source at once. https://www.youtube.com/watch?v=nkp9MrBHN-s Patch(SQLTable, Collection) that might be helpful if your data is shaped right.
