Form fields display values from another record

Hello -

This is prototype app under construction.

I have an issue with a Form control displaying values in fields that are actually blank in the table. This happens when navigating from another record in the gallery that has those same fields filled in.

See series of screen shots.

Any idea why this happening?

Can I provide other details of the app to help troubleshoot?

Thanks for any guidance!

Navigate to another record ...

Navigate back to record 100202

Hello @Cgangweg01,

Yes, you can reset the variable and form control and use this variable in the form’s Item property like this.

On the gallery OnSelect:

UpdateContext({_selectedItem:Blank()}); ResetForm(YourFormName); //YourFormName - Replace with your form name UpdateContext({_selectedItem:ThisItem});

Form Item Property:

_selectedItem

Resetting the form forces it to reload the selected record and prevents values from carrying over when fields are blank.

Thank you @Kalathiya

Giving that a try.

What do I do with the ViewForm expression in the Gallery OnSelect property?

//ResetForm(Form1);ViewForm(Form1)

@Cgangweg01, Not an issue, you can still use ViewForm. Just make sure you also set the variable and reset the form, like this:

Updated code:

UpdateContext({_selectedItem:Blank()}); ResetForm(Form1);ViewForm(Form1); //Form1 - Replace with your form name UpdateContext({_selectedItem:ThisItem});

Hope this worked! Let me know if it’s showing the selected record correctly now.

Hi @Kalathiya

Thank you so much for the replies.

It didn't work. I'll try again later.

I'm sure it is something else I've already done in the app interfering with your suggestion.

What else can I share with you?

Hello @Cgangweg01,

If it’s still not working, it’s probably something else is affecting the form.

To help troubleshoot, it would be great if you could share:
#1. The gallery OnSelect formula
#2. The form’s Item property
#3. Whether it’s an EditForm or DisplayForm that your are using
#4. Any other formulas that you have writen in Default Property or anywhere if yes, please share.

Hi @Kalathiya,

Really appreciate your help.

I added the suggestions above again and it seemed to work at first when previewing but then when I played the app the issue started again and then previewed again the issue was back. Very strange.

Various screen shots to help troubleshoot ...

Gallery OnSelect as suggested

Gallery items - I need conditional filtering

Form items as suggested ...

Edit Form?

Hello @Cgangweg01,

In Play mode, please perform a hard reload until the new version notification appears.

If you’re still facing the same issue:

#1. In the Default property of these three fields, what value have you entered?

#2. Have you added any custom code? If yes, please share a screenshot.

Alternatively, you can try the following code in the Form Item Property:

LookUp(YourTableName,ID=_selectedItem.ID) //YourTableName - Replace with - your table or list name

Hi again @Kalathiya

No custom code to share.

All the fields on the Form have this as their data card Default value.

ThisItem. the field

Also, it appears to only happen to Number column fields.

Hello @Cgangweg01,

Could you please try the approach below?

Write the code in the control’s Value property inside the DataCard in the form.

Please apply this to all 3 columns where the values are not updating.

Value Property:

_selectedItem.ColumnName // _selectedItem = variable name, ColumnName = column name. // Replace with your actual names.

Hello @Kalathiya

Expression valid but that didn't work. Still showing values from previous record.

Below is what AI-Copilot said but I don't understand its recommendations. I don't think they fit.

************************************************************************

Thanks — Number Input (modern) + Dataverse Decimal is the exact combo where this “shows values from the previous record when the new record is blank” commonly happens.

What’s wrong (root cause)

✅ The modern Number Input control can’t truly display Blank()

When Hours1 is blank in Dataverse (Blank() / null), the Form tries to push that blank into the control. But the Number Input’s internal Value is a number, not “nullable”. So when it receives blank, it often:

keeps the previous numeric value already in the control state, or

falls back to a default (often 0) depending on your config

This is why it looks like record B “has” Hours1 even though the table is blank — it’s a UI control state issue, not Dataverse “copying values”.

✅ Dynamic mode switching (View/Edit/New) can preserve control state

When you switch modes without resetting, the card controls may retain their last entered/displayed value until explicitly reset/rebound.
