Hi @Anonymous :
Could you tell me:
- Are you using a button in the canvas app to submit records in from control?
- What is the from control's DefaultMode property?
- What is the button's OnSelect property?
- Do you have "write" permission to this SharePoint List?
First of all,please check the from control's DefaultMode property and set it to
FormMode.New
or
FormMode.Edit
Then,test the submit button again.
Secondly,If the problem persists, please check your permissions to the data source.
Add a label control and set it's Item property to:
DataSourceInfo(YourSPlist,DataSourceInfo.EditPermission)
If it is "false", it means you don't have edit permission for the data source.
In addition,If you need further help, could you describe your app and requirements in detail?
Best Regards,
Bof
