Delegation warning using Filter IsBlank on a sharepoint list datasource

(0) Share

Report

Posted on by PowerPete13

Need help/recommendation to eliminate a delegation warning on a visitor management power app I built. The datasource is a sharepoint list.

The delegation warning is from a dropdown menu, listing the names of visitors (a text Column) who have not checked out. The dropdown items are the names of said visitors (text Column) - based on the 'Checkout DateTime' column (a date Column) of the corresponding row on the sharepoint list being Blank...

I have adjusted the datarow limit to 2000 but that makes no difference. Below is the formula I am using under the items property of the dropdown:

Filter('DataSource', IsBlank('Checkout DateTime'))

This works - but there is got to be a better way. I'm still kind of green with powerapps sorry...

Thanks for any help!

hey @PowerPete13

is your itemcount of your datasource (sp list) greater than 2000 entries? if not you can ignore it. Setting the value to 2000 does not solve the issue itself, the delegation warning will always be there.

what you can try is to store the date you selected into a new text colum/input.

for the text property you put:
Text(DatePicker1.SelectedDate, "dd/mm/yyyy") please be aware that you need to rename the Datepicker1 with the actual name of your datepicker. in the filter statement itself you just need to try the newly created text column/input.

If it work you can set the visible property of the text date field to false so its just for the filtering purpose.

Let me know if my answer helped solving your issue.

If it did please accept as solution and give it a thumbs up so we can help others in the community.

Greetings

Try:

Filter('DataSource', 'Checkout DateTime' = Blank())

To get around the delegation limitation of a SharePoint List

Hope that helps,

Bryan
