Slowness in Power apps using modern controls

(0) ShareShare
ReportReport
Posted on by 431

Hello Power Users,

 

I've started using modern controls and built a power app using them and data verse as datasource. I have around 80 columns in the data verse table. So far I had around 50 columns used inside the power apps.

 

The issues that I've encountered are:

1. Slowness while loading of controls on the form like display a field based on a drop down value, scrolling up and down to access all the controls and switching from preview mode to development and from dev to preview mode.

2. I don't see any data inside the table even I submitted few records. It says "Sorry something went wrong, please try to reopen".

3. Also, sometime while I try to save or publish the edits the page is unresponsive says "Page Unresponseive You can wait for them to become responsive or exit the pages".

 

Can anyone please let me know if you have come across this issues? If yes, any suggestions or best way to handle such issues.

 

Can anyone please help me. Thank you so much in advance!

    A few things that may help:

    • Ensure the "explicit column selection" setting is turned on for your app
    • Make sure the Fields property for each modern combo box shows only the fields necessary for that combo box to work properly
    • Ensure you have dealt with any delegation warnings flagged by the app

    That said, I remember testing the modern combo box about 6 months ago and it does not correctly delegate to Dataverse. It will read a maximum of 500 rows, no matter your app settings or delegability of the query. For that reason alone, I have continued to use the classic combo box.

     

    Hope that helps,

    Bryan
