Hi @CU30040755-0,

You can use IsMatch on your TextInput. For your requirement (at least one special character, one number, and one letter), something like this works:

IsMatch( TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[^A-Za-z0-9]).+$" )

You can plug this into your validation logic (e.g., show error, disable button, etc.).

Hi @CU30040755-0

It looks like you want to validate a TextInput so that it contains:

At least 1 letter

At least 1 number

At least 1 special character

In Microsoft PowerApps, you can achieve this using IsMatch() with a regex pattern.
Validation Formula

IsMatch(
TextInput1.Text,
"^(?=.*[A-Za-z])(?=.*\d)(?=.*[@$!%*#?&]).+$"
)

If you want to disable the Button/Icon - until this text is not valid - use this on the button/icon display mode

If(
IsMatch(TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[@$!%*#?&]).+$"),
DisplayMode.Edit,
DisplayMode.Disabled
)

Hi,

Got it — you want to validate a TextInput so that it contains:

at least one special character

at least one number

at least one letter

In Power Apps, the cleanest way to do this is using IsMatch() with a regex pattern.

Set your validation formula like this:

IsMatch( TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[^A-Za-z0-9]).+$" )

What this checks:

(?=.*[A-Za-z]) → at least one letter

(?=.*\d) → at least one number

(?=.*[^A-Za-z0-9]) → at least one special character

You can use this in different ways.

If you’re using a Cancel icon or Submit button:

If( IsMatch(TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[^A-Za-z0-9]).+$"), Notify("Valid input", NotificationType.Success), Notify("Must contain letter, number and special character", NotificationType.Error) )

Or to disable a button until valid:

DisplayMode = If( IsMatch(TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[^A-Za-z0-9]).+$"), DisplayMode.Edit, DisplayMode.Disabled )

So basically, this ensures your input meets all three conditions before allowing any action.

Use the IsMatch function with a regex pattern to enforce at least one letter, one number, and one special character. This is the most reliable way

to validate complex input rules in Power Apps.

most likely below :

!IsMatch(TextInput1.Text, "^(?=.*[A-Za-z])(?=.*\d)(?=.*[^A-Za-z0-9]).+$")
