I have a Parent Table called Items. And in it's Form I have a subgrid populated by it's child table , ItemSpecifications.

I want to prevent users from deleting Item Specifications, for those items for which Parent Record's (Item's) Choice Column = Approved.

Is there a way to disable delete option in the subgrid's context menu as well as on the ItemSpecifications Form conditionally.

Or is there an event that fires before delete to prevent delete

You can register a pre event on Delete message and run the desired logic and control is centrally.

what @shashankbhide suggested if I understood correctly is to write a plugin and registering it on the Delete message (I just write because I didn't read plugin and if you are not aware of what plugins are at least now you have all the terminology to search for)

an alternative as you are checking the parent, can be a synchronous workflow, I didn't test your exact scenario but it should be possible (keep in mind that synchronous workflows are an old technology inside dataverse)

don't know if can be done with low code plugins (using power fx) but they are on preview and between all the methods I personally prefer writing a plugin for this kind of logic as was suggested

Hi @Rutu01 ,

I agree with @shashankbhide, @GuidoPreite.,but here is my take on this.

You can register a Plugin on the child entity on Pre validation Step of Delete Message to perform your intended operation.

If you want to disable the Delete button altogether, you need write a Display rule using Power Fx.
