Validation of empty TextInputs in a Gallery

[EMARIN91]

Hello everyone,
I have created a Gallery to which I have inserted two TextInputs to take millimeter and pressure data of the tires of a vehicle.
What I need is a formula that validates all the TextInputs in the Gallery, and if in a given case there is one or more empty TextInputs the Collection can not be saved and do not pass to the next screen.

The conditional formula that I am using in a button is the following:

If (TextInput_mm.Text = "" Or TextInput_psi.Text = ""; Navigate (Alerta_Validacion; ScreenTransition.Cover); ClearCollect (LlantasMP; ForAll (Gallery_Llantas4.AllItems; {IdLlanta: IdLlanta; Millimeters: TextInput_mm.Text; Pressiones: TextInput_psi. Text})) ;; Navigate ('Semanal (Mptor)'; ScreenTransition.Cover))



This formula is only validating correctly the first 02 TextInputs of the first rim (TextInput_mm and TextInput_psi), but not with the others.

Hello,

You can try instead of 

TextInput_mm.Text = "" Or TextInput_psi.Text = ""

the following:
LookUp(Gallery_Llantas4.AllItems,IsBlank(TextInput_mm.Text)||IsBlank(TextInput_psi.Text),true)

Hi @EMARIN91 

Can you please modify your expression as:

Clear(LlantasMP);
ForAll(
    Gallery_Llantas4.AllItems;
    If(
        !IsBlank(TextInput_mm.Text) && !IsBlank(TextInput_psi.Text);
        Collect(LlantasMP;
        {
            IdLlanta: IdLlanta; 
            Millimeters: TextInput_mm.Text; 
            Pressiones: TextInput_psi. Text
        }
        )
    )
    );
If(CountRows(Gallery_Llantas4.AllItems) = CountRows(LlantasMP); Navigate ('Semanal (Mptor)'; ScreenTransition.Cover);Navigate (Alerta_Validacion; ScreenTransition.Cover))

This iterates over all the items in the Gallery and collects the collection. At the end checks the condition if all Gallery items were added to collection, then navigate to 'Semanal (Mptor)' screen, else navigates to 'Alerta_Validacion' screen.

Hope this Helps!
