Hello, supportive community,
Here i found something (it's glitch or bug or something from my end mistake),
when we select any row from child form and edit that row, its open edit form for that row respectively,
when we close that form then there is no worry, but when we save that form, the is refresh and still we can show 'Edit' and 'Delete' button, but not any row is selected (bit confusing right?).
Here i attached some screens for better understanding,
After save child form
as you can see an image, we can still got the option for edit/delete the last selected item.
Thanks and Good day ahead...!
