Modern Control in Power-Apps

I’m working with a modern form control in Power Apps to update training records. There is an existing record where all fields, including the Training Date, are already populated.

When the form is in View mode, the Training Date control (DataCardValue_TrainingDate) correctly displays the stored date.

However, I don’t want users to modify this field, so I’ve set:

DataCardValue_TrainDate.DisplayMode = DisplayMode.View

Now, when I switch the form to Edit mode, the Training Date field becomes blank, even though the data exists and the control is still set to View mode.

Requirement:

I need the Training Date to be visible (read-only) in both View mode and Edit mode, without allowing users to edit it.

Issue:

Why does the date disappear in Edit mode, and how can I ensure it consistently displays the existing value regardless of the form mode?

@Power Platform Guy,

I too experience this issue while designing with Modern forms based on the experience which i had

In EditForm mode, the control: Stops binding to ThisItem properly and it Doesn’t auto-populate from the record this causing the Result → Blank value displayed

Unlike Classic controls, Modern controls don’t automatically retain the value when forced into View mode inside an Edit form.

Instead of relying on default binding, force it like this:

If(

    !IsBlank(Parent.Default),

    Parent.Default,

    ThisItem.ColumnName

)

(Or) Coalesce(Parent.Default, ThisItem.ColumnName)

Hi @Power Platform Guy,

Modern controls in edit forms don't retain their bound value when DisplayMode is forced to View on the control itself, because the form's edit context resets the control's binding.

The fix, set the Default property of the DataCardValue to explicitly reference the record:
Coalesce(Parent.Default, ThisItem.TrainingDate)

This ensures the date always shows the stored value regardless of the form mode.
For the read-only requirement specifically, there's a cleaner approach that avoids the blank issue entirely: instead of setting DisplayMode.View on the date picker control, lock the entire data card instead. Set the data card's DisplayMode property to:
Parent.DisplayMode = FormMode.Edit : DisplayMode.View : Parent.DisplayMode
This makes the card read-only in edit mode while still showing the value correctly, without fighting the modern control's binding behavior.

Best regards,

Valantis

For a field that is always read-only, the preferred solution is to display the date in a Label or use a disabled Date Picker instead of setting the Modern Date Picker to DisplayMode.View. If the issue persists only with the Modern control and all properties are configured correctly, it is likely a current limitation of the Modern Controls framework.

If you need a more specific solution, please share:

Your data source (SharePoint, Dataverse, SQL, etc.).

Whether you're using a Modern Form or a Classic Edit Form.

The formulas for the DataCard Default, DataCard Update, and the Modern Date Picker's Value/Default property. This will help determine whether the issue is due to configuration or a known control limitation.
