Scenario

You have a SharePoint list and a custom new/edit/delete form for it. The custom form will allow controlled editing of the item, plus some validations.

It means User A cannot edit User B’s item. How to achieve this?

Solutions

I am recommending various solutions for this scenario.

Solution 1: Item Level Permissions

One easy solution is using the List, Advanced Settings, then Item-Level Permissions.

Advanced Settings

But, this solution won’t work if you need Approvers group to edit the items.

Solution 2: Delete Edit Form using SharePoint Designer

Here we can delete the edit form of list & provide another custom HTML form to manage the restricted edit. To delete the edit form, here are the steps:

Open the list in SharePoint Designer, thenLocate the EditForm.aspx and Choose Delete option.

Open SharePoint Designer and click Your list.

Go to the Forms section as in the following screenshot:

From the ribbon choose the Delete option.

From the ribbon choose the Delete

Save changes and now Open the list in browser.
