Hello everyone,

I am working on a Power Apps application and I need help with the "Save" button formula in the context of a nested gallery. My goal is to save the following information to a SharePoint list: the person's name, the activity, and the type of position selected from a dropdown list.

Here’s a preview of my interface: 

  

 

The data needs to be saved in the SharePoint list, which has the following columns: Date, Collaborator, Activity, and PositionType.

Thank you in advance for your help and advice on how to implement this functionality with a nested gallery!
 
 
 

Best regards,

    You could try this just make sure you change name of your data source 

    ForAll(
        gal_Collaborator.AllItems,
        With(
            { varCollaborator: ThisRecord.Collaborator },
            ForAll(
                gal_Activity.AllItems,
                Patch(
                    'SharepointList',
                    Defaults('SharepointList'),
                    {
                        Date: dp_Date.SelectedDate,
                        Collaborateur: varCollaborator,
                        Activité: ThisRecord.ActivityName,
                        TypePoste: drp_Position.Selected.Value
                    }
                )
            )
        )
    );
    Notify("Activities saved successfully!", NotificationType.Success)

    Not best Use of ForAll (Should not use it in big data sets as loop) but should work with Your example :)

    Thank you SebS, I tested your formula, but with the double ForAll, the data is not saved. When I keep just the first ForAll, the data is saved, but when I add the second ForAll to access the data from the nested gallery, nothing is saved.

     

    I modified the formula, but still nothing. Do you have any other ideas?

     

       ForAll(
           Gal_Collaborateur.AllItems, 
           With(
               {
                   CollaborateurName: ThisRecord.Personne 
               },
               ForAll(
                   Gal_Activité.AllItems, 
                   Patch(
                       'Suivi des activités',
                       Defaults('Suivi des activités'),
                       {
                           Collaborateur: CollaborateurName, 
                           Activité: ThisRecord.Activité, 
                           TypePoste: ThisRecord.ddl_Valeur.Selected.Value,  
                           Date: Datepicker.SelectedDate 
                       }
                   )
               )
           )
       );
