OnChange not firing

Hi there,

I have an OnChange function on a text input (# Students) that is designed to update all records in a gallery (# Stud.) when the number is changed. While i was using a SharePoint list as my database, it worked great, but now that I've moved over to an SQL DB, it doesn't seem to be firing when changed.

UpdateContext(
 {newStudents:
 'UE - Value - # Students'.Text}
);
ForAll(
 'UE Unit Gal'.AllItems,
 Patch(
 '[dbo].[Units]',
 LookUp(
 '[dbo].[Units]',
 ID = Value('UE Gal ID'.Text)
 ),
 {
 'Number_x0020_of_x0020_Students': Value(newStudents)
 }
 )
)

The offending input is the one with the delegation error. If anyone can help me remove that as well, I'd be very grateful!

Hey @EpicTriffid

Can you try to update the expression as:

UpdateContext( {newStudents: Value('UE - Value - # Students'.Text)} ); ForAll( 'UE Unit Gal'.AllItems, Patch( '[dbo].[Units]', LookUp( '[dbo].[Units]', ID = Value('UE Gal ID'.Text) ), { 'Number_x0020_of_x0020_Students': newStudents } ) )

Are you getting any errors? To check if the OnChange is getting triggered, add the below expression on the OnChange property as:

Notify("Getting triggered");

If you are able to see the notification, then the issue is with the Patch query and OnChange is getting triggered.

Note: OnChange only gets triggered if the user clicks outside the text input.

Hope this Helps!

Hi @yashag2255 ,

Thanks for the help. I adapted it as you said, and no errors that I can see. The notifation does come through, so do you have ideas what might be wrong with the Patch? Is there a problem between ForAll and SQL?
