Now I have added a Nintex forms web part on a page and have configured it to have the 'Edit' view displayed for the form. You need to provide the Item ID which has been set to 1. So the forms works fine, opens up the list item where ID = 1. Now when i click on my custom Button mentioned above, it takes me to the back end page 'EditItem.aspx' as it is configured to do so.
I'm wondering if theres a way to change the ID of the list item to be displayed on the fly on the Nintex Forms web part?
