Hello, guys. I just don't know what to do anymore, so PLEASE, give me a hand or two, if possible...
I have a job to do to my boss. I creater a powerapps screen that saves data in a Sharepoint List, but one field of this screen, a combo box, receives data from the List to charge the choices available.
So here we are:
If I let any of the marked fields (*) blank and press "Save", it is supposed to appear an error screen:
So If I fill the blank fields, everything's ok!
BUUUUUT if I unmark, de-select the combobox previously selected item...
It keeps saving the data of this page on my Sharepoint List, and without one of the mandatory values... Did you understand?
This is what I put on Save button:
If(
!IsBlank(Titulo_Novo.Text) && <- this is the first mandatory item
(!IsEmpty(Unidade_Departamento_Regiao_Novo.Selected.Value) Or <- this line...
!IsBlank(Unidade_Departamento_Regiao_Novo.Selected.Value) <- and this line were supposed to be working, checking if the field (combo box), which is the second mandatory item, is not empty or is not blank!
)
&&
!IsBlank(Objeto_Novo.Text) <- this one is the third mandatory item.
;
Set(Borda_TituloNovo; Black);;Set(Borda_UnidadeNovo; Black);;Set(Borda_ObjetoNovo; Black);;Set(Borda_ValorNovo;Black);; <- here I'm turning all the three mandatory items borders black.
UpdateContext({Popup_Salva_Item:true}) && UpdateContext({Fundo_CinzaNovo:true}); <- here I'm showing an pop up information message and a gray screen behind it.
UpdateContext({Popup_Alerta_Campos:true}) && UpdateContext({Fundo_CinzaNovo:true}) <- here I'm showing an pop up warning message and a gray screen behind it.
)
The warning message should pop up on the screen if any of the three mandatory itens were blank.
Why the heck is that rule on the save button working for the combo box only if I select and item and de-select it? How should it be the correct way to write this rule?...
