PowerApps Button control

Hi,

I am building a powerapp that can be used to register for events.

I have added a gallery and the data source is a Sharepoint event list. Different events will be displayed according to selected category from dropdown.

If a user clicks 'Subscribe' button for an event, the user details will get saved in a Sharepoint list and the button should be disabled if the user clicks on it once and should remain disabled for selected events after refresh too.

I've tried many ways to disable the button according to requirement, but nothing worked.

Can anyone please help with the solution.

Hi @AP_95
If you save user details about the event in a SP list already I guess you can Disable the button using a filter against that record you just created, using a filter or lookup query in the DisplayMode-property on the button.
Something like
If( IsBlank( Filter( SharePointDetailListEventName = Gallery.Selected.Name && SharePointDetailListUserEmail = User().Email) ), DisplayMode.Edit, DisplayMode.Disabled )
This assumes you have info in the detail list about event name and user email, but it could be any unique keys that you have there.

Hope that helps in the thought process!

Thanks @Devvj
I used lookup instead of filter and it worked.
