On subgrid record click open quick create form in crm 365 Uci 9.1

Hi All,

I have 2 case type form suppose A & B forms on Case entity & in both forms contains a subgrid to custom entity called Action.So here in A form on selct of action subgrid record it should open with quick create edit form & in another B form on subgrid record select it should open the main regular form not the quick create.

Here am using read only grid not editable grid.so which event i should use or is there any other way available though ribbon.

I have tried with edit oob button on record select when click on edit but it seems not working as formcontext is getting undefined.

Any help would be appreciate.

Thanks,

Jharana
