I have build the app from blank canvas and connected to data source. I don't have browse gallery in my app.
I want employee to register the detail and view their profile and edit the details.

I added form to each screen.
Item property = 'Defaults.EmpReg' .
To get the data registered to view employee profile
updated text property = Emp_Edit.LastSubmit.Title
When editing existing detail, its adding new record in the sharepoint list, not updating the existing value.
I dont know where am going wrong. Please help me.
