Data Validation

Hello,

Can you use Power Apps to validate user input against data in a database, i.e. if I ask for them to provide an email address, it must correspond to one we have in our database?
 
Thanks,
 
James

    hey
     
     
    yes u can do this for example with this:
    LookUp(DataSource, Email = TextInput1.Text)
    
    if you want to show a error message for example you can use:
    If(IsBlank(LookUp(DataSource, Email = TextInput1.Text)), "Email not found", "Email verified")
    
    if it was helpful please mark as verified answer
     
     
    cheers
