version 3.19074.24 drop down differences between studio preview mode and running the published PowerApp

[NigelP]

Hi 

I have a Drop down whose source is a list.  In the OnChange property I have :-

If(!gFirsttimeApprovalDashboard,

Set(gFirsttimeApprovalDashboard,false);

Navigate('Approval Dashboard Screen', Fade)

)

If I use the Preview in the PowerApps Studio, this works fine.  The screen is refreshed and the new value in the drop down is used to filter the gallery.

If I run the published PowerApp then then after the first time,  the changed value is not used to filter the gallery and the gallery is not refeshed.

Regards

Nigel

Hi @NigelP ,

Could you please share a bit more about the Filter formula you used in your Gallery?

Could you please show more details about the issue within your app?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. The screenshot as below:

Add a Dropdown control, set the Items property to following:

Choices('20190701_case7'.Status)   /* <-- Status is a Choice type column in my SP list */

Add a Gallery, set the Items property to following:

Filter('20190701_case7', Dropdown1.Selected.Value in Status.Value)

Please check if you have typed a proper Filter formula within your Gallery Items property. On your side, you may type the following formula:

Filter('YourDataSource', FilteredColumn = Dropdown1.Selected.Value)

The published app screenshot as below:

Also please consider take a try to turn off the "Improved app rendering (final validation)" option and "Explicit column selection" option within Advanced settings of App settings of your app, then re-publish your app, check if the issue is fixed.

If the issue still exists, please consider re-create a new app based on your data source, then try above solution again, check if the issue is solved.

Best regards,
