Issue with comparing datepicker value with related sharepoint column

Posted on by BurtekWu

Hello everyone,

I am building gallery in PowerApps in which users shall be able to update date with power picker feature. I am linking it to Sharepoint list in which i have Date column.

I am trying to check if user changed date, to verify if gallery row needs to be patched to shp.

DefaultDate for datepicker is set to ThisIstem.assignmentEndDate.

I am trying to compare ShP list, to datepicker value, but for each time I receive True response for below conditions:

1st try: ThisIstem.assignmentEndDate <> dpAEndDate.SelectedDate

2nd try: Text(ThisIstem.assignmentEndDate, "dd/mm/yyyy") <> (dpAEndDate.SelectedDate, "dd/mm/yyyy")

With bot config I receive TRUE response, even if date was not updated, and is presenting Date stored in Sharepoint.

Therefore can anyone advise me how to compare data between datepicker and shp "Date and time" list column correctly?

In the OnSelect of the datepicker, set a variable to the current value.

UpdateContext({dtmOldValue: ThisIstem.assignmentEndDate});

In the OnChange of the DatePicker, check for equality, then react accordingly.

If(dtmOldValue <> dpAEndDate.SelectedDate,

Patch(...

)//End Patch

); //End If

Hi, I tested your approach and I received a correct comparison result, so I am unsure what causes the problem in your case.

But I have an idea for you. Instead of comparing, you can set the OnChange property of your DatePicker control as:

Patch('Test List',LookUp('Test List', ID = ThisItem.ID),{assignmentEndDate: dpAEndDate.SelectedDate})

where 'Test List' is the name of the SharePoint list.

Let me know if this helps!

Issue with comparing datepicker value with related sharepoint column

Hi AndrianaO , abc 123,

I wanted to avoid using OnChange property, as I have over 30 columns in this gallery, so it's not the most efficient way of patching updates. I wanted to use Toggle as indicator of updated rows.

I was expecting result the same as in AndrianaO case, but in my case it's not working. I am surprised that also using Text() approach is not working - despite it shall return the same results.

I believe my issue might be result of some locales config difference between PowerApps and related ShP... I have to dig deeper.

Anyway, thank you for provided answers so far.
