Hi,

I am getting the no item to display in my preview screen . Ive looked online for solutions and i have changed the default mode is new.

I submit both forms. Seems like I have to exit out of preview mode then resubmit to get my 2nd form to be submitted.

My 2nd form is linked to datacards in my first form.

when outside of preview i see the values fine. -

Action History Default property - DataCardValue1.Selected.Value - which is the value of Action from Editform1.

Date History Default property - DataCardValue2.SelectedDate - which is the value of Date from EditForm1

Any fix to this?

@wonka1234 Probably not, you may want to try to use a different one, such as gblRecordID_B to be specific to the one for Data Source B

Re: No item to display in preveiw screen when default mode is NEW

@poweractivate So my editform1 has the item property - LookUp('DataSource A',ID = gblRecordID)

and i copied that same for my 2nd form - LookUp('Data Source B',ID = gblRecordID).

Should these be the same record ID variable?

Re: No item to display in preveiw screen when default mode is NEW

This may also help:

Setting up the DefaultMode: You can conditionally set the DefaultMode of the form to FormMode.Edit or FormMode.New based on whether gloCurrentItem is blank.

If(IsBlank(gloCurrentItem), FormMode.New, FormMode.Edit)

This should set the form mode to "New" if gloCurrentItem is blank, and to "Edit" if it's not.

Put this in the App OnStart if needed:

Set(gloCurrentItem, Blank())

Then click ellipses to right of App --> Run OnStrat to simulate running app from beginning while still in editor.

Adjusting OnSuccess: In the OnSuccess property, update gloCurrentItem as I have already suggested.

Set(gloCurrentItem, Self.LastSubmit)

Resetting the Form: If you are using a button to submit, consider resetting gloCurrentItem to blank when you want to insert a new record, with a reset button, on its OnSelect property:

Set(gloCurrentItem, Blank()); NewForm(YourFormName)

This will allow the form to be ready for a new submission since gloCurrentItem will be blank and DefaultMode will revert to FormMode.New.

And then I assume you already have a Submit button whose OnSelect may be:

SubmitForm(YourFormName)

@wonka1234

In the Form Item property you may need a variable, such as gloCurrentItem
So then in the Item property of your Form, put this formula:

gloCurrentItem

In the OnSuccess property of same Form, you may need to use formula

Set(gloCurrentItem,Self.LastSubmit)

somewhere in there.

Then the last submitted item may show on the Form after submission.

See if this may help further @wonka1234

@wonka1234

If you have formulas in OnStart these never run in the Power Apps Editor automatically,

you need to manually click Run OnStart each time in the editor. Here are the steps below:

1. Click on the ellipses to the right of the word App
2. From the menu, click Run OnStart

3. Then enter preview mode.
4. Repeat the above steps each time you want to pretend you are starting the app from the beginning in the Power Apps Editor.
