Canvas App New Form-after 1st submission returning to the page shows a blank page

Posted on by James Reinhardt

I have a simple Canvas App with a form tied to a dataverse dataset. The form is set with a Default Mode of 'New'. The OnSuccess action of the form navigates to the home page after submission.

When I open the form for the first time, it displays as below and successfully saves the record to the dataset.

However, when I navigate back to the form it is completely blank.

From what I have been able to figure out, after the New form is submitted, the form is switched to Edit mode and expecting to display the newly created record (which is the same blank screen as below).

I assume I need to reset the form, or change the navigation to this form to expressly request a form mode of 'new'. Thanks in advance for your help!

The key is the Item property of the form. You can set it to Lookup(yourdatasource, ID=Gallery1.Selected.ID) It is ignored when the form is in New mode but when the form is in Edit mode, it will show the item selected in the gallery. Typically you would select the record inside the gallery and navigate to the edit screen. You can set it by putting an icon inside the gallery with the OnSelect property: EditForm(yourformname); Navigate(yourformscreen). For creating a new record, on the gallery screen, there should be an icon or button outside the gallery with the OnSelect property, NewForm(yourformname); Navigate(yourformscreen).

How did you set the 'New' Mode?
Ensure the button/action item you're using to navigate to the form have the NewForm command
Navigate(MyFormScreen,None); NewForm(Form1)

Thanks for the response, but I don't have a gallery, or a reason to view any existing records. What I'm trying to do is bypass that automatic display of the submitted record. I think I figured out something that works, will post about it in a separate reply.

I was able to get the desired behavior by doing the following:
For the Submit button, I added the following to the OnSelect:
SubmitForm(EditForm1);NewForm(EditForm1)
and added Navigate(Home) to the OnSuccess.
The user never sees the NewForm, but it seems to reset things so the next time it is viewed it is in New Mode.
