Using Patch and LookUp to udpate a Sharepoint list

(1) Share

Report

Posted on by ancorte

I have a Gallery 01, and filter this Gallery 01 I collect in another Gallery 02 some record from the Sharepoint list “SpeseV01”.
In this way I create with the selected record in the Galley a collection “MyCollection”.
I modify the value of some records in the collection, and after I want update the record in the sharepoint list.
To make this, I have two buttons ( I’m not able use only one button, and I don’t’know why).
The first button in the “OnSelect property” has:
“ClearCollect(MyCollection; Gallery3.AllItems)”
So in this way I have all the elements modified in the collection.
The second button in the OnSelect property has :
“ForAll(
MyCollection;
Patch(
SpeseV01;
LookUp(SpeseV01; ID = ThisRecord.ID);
{ Title: txtTitolo.Value;
TipoSpesa: dropTipoSpesa.Selected;
Importo: numImporto.Value;
DataSpesa: dateDataSpesa.SelectedDate;
Pagamento: dropPagamento.Selected;
Fornitore: txtFornitore.Value;
Note: txtNote.Value;
DataRimborso: dateDataRimborso.SelectedDate;
IDRimborso: txtIDRimborso.Value
})
)

But it doesn’t’ work.
If I use the monitor, the error is :
“Fetching Items failed. Possible invalid string in filter query.”
What can I do ? I’m new of patch and LookUp function.

Hi @ancorte

The fundamental issue here is that you cannot Patch from the Collection while referring to the control values in the Gallery - either do one or the other - Patch from the Gallery and refer to the control content
Patch( SpeseV01; ForAll( Gallery01.AllItems As _Data; { ID: _Data.ID Title: _Data.txtTitolo.Value; TipoSpesa: _Data.dropTipoSpesa.Selected; Importo: _Data.numImporto.Value; DataSpesa: _Data.dateDataSpesa.SelectedDate; Pagamento: _Data.dropPagamento.Selected; Fornitore: _Data.txtFornitore.Value; Note: _Data.txtNote.Value; DataRimborso: _Data.dateDataRimborso.SelectedDate; IDRimborso: _Data.txtIDRimborso.Value } ) )

or Patch from the Collection and refer to the field names in it (I have assumed the names here)
Patch( SpeseV01; ForAll( MyCollection As _Data; { ID: _Data.ID Title: _Data.Title; TipoSpesa: _Data.TipoSpesa; Importo: _Data.Importo; DataSpesa: _Data.DataSpesa; Pagamento: _Data.Pagamento; Fornitore: _Data.Fornitore; Note: _Data.Note; DataRimborso: _Data.DataRimborso; IDRimborso: _Data.IDRimborso } ) )

The actual problem is the Patch..For All (i'm not sure to have understood exactly how it works).

In the Gallery i have only the record that i filtered with another Gallery (and it's ok.)

For example, if i have 3 records, an modify the value in the field "Import", when i push the button it modify with the new value of "Importo" all the 3 records.

The "Onselect" property of the button, applying your suggestion, is this (but i can made an error...)

Patch(SpeseV01;

ForAll(Gallery3.AllItems As _Data;

{ID: _Data.ID;

Title: txtTitolo.Value;

TipoSpesa: dropTipoSpesa.Selected;

Importo: numImporto.Value;

DataSpesa: dateDataSpesa.SelectedDate;

Pagamento: dropPagamento.Selected;

Fornitore: txtFornitore.Value;

Note: txtNote.Value;

DataRimborso: dateDataRimborso.SelectedDate;

IDRimborso: txtIDRimborso.Value

})

)
