As you open the app there is a gallery which is showing a list of entries from my master data list, from SharePoint.
When I select to open an item it navigates to a new screen ('Navigate(scr1)'), which displays the selected item details in a view form (Item= gallery1.Selected).
I have added a button to allow me to edit the form details for this selected item. Once I have edited the fields and click the submit button, which has only 'SubmitForm' and 'ViewForm' (previously had 'ResetForm') in the code, the form then changes from the item I previously selected in the gallery to the latest item in the gallery/list.
Any reasons why this may be happening?
