Hi,

I'm making an app where the users have two inputs field ("Accepted" or "Not Accepted"). The user is then supposed to type in the number of accepted and not accepeted materials. The data source to the gallery is a collection "col_event_taskReturn". When any values is changed in the input field the collection should be updated.

To updated the collection I'm using onchange property,

Patch(
col_event_taskReturn, 
ThisItem, 
{ 
ACtemp: Value(item_appaccepted_1.Text)
}
);

everything is working fine if the input field is visible on the page. But the gallery contains of 20-30 records, therefor the user can't see all the records, and have to scroll down. The issues is then if the user is typing values into the textfield in the first record, and then have to scroll down to the button on the gallery to input another value. The collection is not updated with the value typed into the first record (onchange is not fired).

I'm really stuck how to solve this issue? It seems like a bug in power apps? is there a workaround?

Hi @Kasper_L ,

Yes, it's a known issue. Users need to click/tap somewhere else on the screen after filling in the text input box to trigger the OnChange property. Once the item leaves the display area, it will no longer be triggered.

Best regards,

Thanks for the response @v-jefferni

My workaround is to use a forall just before all the data is saved to dataverse, just to be sure that everything is saved correctly

ForAll( Gallery1_8.AllItems, Patch(col_event_taskReturn, ThisRecord, { REtemp: Value(item_scrap_2.Text), ACtemp: Value(item_appaccepted_3.Text) } ) );
