show Error message to user

[rahmanig]

Hi, 

I have a form and on selecting the save button I would like it to show a message to users if one of the dataCard is empty. so this is my code:

If(!IsBlank(DataCardValue13.Text), And(SubmitForm(Form1),Navigate(PartnerSearch, ScreenTransition.Cover)),Label10.Text="error")

So I dont understand why the message does not show? 

the save button wont work unless the datacard have some text. 

Appreciate your help.

Thanks

Hi

Chain reaction in PowerApps use ";".

To show something, use UpdateContext({contextvariable: true})

Your error message resides in a label called

- Label10.Text with "error" text.

Set the Label19.Visible = show (or any name you wish)

In your case, when you click Save Button, you can write

- If(!IsBlank(DC.Text), SubmitForm(Form1); Navigate(Screen1, Transition), UpdateContext({show: true}))

In order to hide the "error" message again, just make sure that when you start to fill in something in DataCard, the error message disappear.

Just use UpdateContext({show: false}) following to your action on the DataCard.

Hope this helps.
