Clear data from gallery

[Paul_dfb]

Hi all. I am building a very simple attendance scanning app. When the instructor scans a bar code it populates a gallery and a share point list.

All this is working fine. However i want the app to have a blank gallery every time the instructor opens it, in other words i dont want them to see the previous days records in the app.

I cant seem to get the gallery to clear all its data. 

Thanks for the help

Paul

Filter the gallery to only show Today

Filter(DataSource, Date = Today())

On the OnStart function create a now variable

Set(varNow; Now())

Then filter the items

Filter(
    SPList;
    varNow < DateColumn 
)

Thanks for your reply. i have added the filter, however it is now showing no information as the bar codes are scanned?

[Nogueira1306]

Filter(DataSource, Date = DateAdd(Today(),0,Days))

unfortunately that doesn't seem to be working. 

this is all i see when using the app. This is after scanning. the items are still going to the sharepoint list.

@Paul_dfb 

What is your Items property for the Gallery?

If you are only concerned with showing "today's" records, then your formula should be similar to the following:

Filter(yourDataSource, Created >= Today())

The above is based on the created date, so specifics would be based on your list columns as to what you want to filter on.

I hope this is helpful for you.

Thanks a million for that. It is working fine now. It is just showing today's scanned info which is all i need. 

Thanks for your help.
