OnChange Label is not updating when value changes

Got a good one this morning which I thought was already solved.

I have a label that shows the number of days an item has been in inventory.

The Default is set to as shown below, for calculating the number of Days since the item was checked in

DateDiff(ThisItem.CheckInDate,Today())

However on the OnChange, whenever the value changes, it's not posting back to the DB. I'm sure its something I'm overlooking here. Any help would be appreciated.

Patch('Customers',ThisItem,{CountDays:NumberofDays.Text})

Thanks!

Please consider changing your Formula to the following:

UpdateIf('Customers',ID = ThisItem.ID, {CountDays:NumberofDays.Text})

If your CountDays column is a numeric column, then change to:

UpdateIf('Customers',ID = ThisItem.ID, {CountDays: Value(NumberofDays.Text)})

I hope this is helpful for you.

Hi @LyonsBI_BRL,

Based on the issue that you mentioned, do you want to update the CountDays based on the Text input on change?

Could you please share a bit more about the scenario?

Your formula is completely correct, this should work if the OnChange fires.

Actually, the OnChange property will be triggered only when the user clicks on anywhere of the screen, and not as soon as the condition is met.

OnChange – How the app responds when the user changes the value of a control (for example, by adjusting a slider).

This is how our official doc defines the OnChange property.

I have make a test for you, please check as below.

You could see that you need to click other place within the Screen to trigger to OnChange property.

As an alternative solution, please consider inset a submit button to trigger the Patch().

Insert a button into the Gallery, set the OnSelect as below:

Patch('Customers',ThisItem,{CountDays:NumberofDays.Text})

Regards,

Qi

As I have a Text Input and I am showing an ID Number ( which is getting from a Variable) and the control is read only mode.

when I save it's not saving that ID number into my Text Column.

I have used this OnChange of the Text Input
