Input Validation

[aruntd77]

Dear Friends,

I am looking out for an option to check if the input text is alpha numeric/email format etc. Please let me know how can I achieve this input validation on Form before submit.

Thanks

Arun

Hi Arun,

So far, I haven’t seen a way to check if the input text is Alphanumeric/Email format. I guess this has not been supported by PowerApps.

May I suggest you submit an idea about this issue at PowerApps Ideas Forum? The link of PowerApps Ideas Forum is:

Best regards,

Is there any sample app to create alogin screen with Dynamics 365 users , after validation, its should go to the next page.

Any sample powerapp is highly appriciated.

I see this is quite an old post so things have changed since, but people might still come here looking for answers so;

I do this with IsMatch using regex - there are a bunch of pre-defined regex pattern options like Email;

IsMatch(TextInput.Text, Email )

returns true if it's formatted like an email using the pattern .+@.+\.[^\.]{2,} (and looking at that, I'm grateful for the predetermined Email pattern!)

Besides the pre-determined patterns, you can obviously apply your own regex, and to test custom patterns I usually use something like https://regex101.com.

You can then communicate to the user in-line with things like the BorderColor property on the TextInput as they enter the data;

If(IsMatch(TextInput.Text, Email), Color.Green, Color.Red)

You can view all the patterns and details for IsMatch here;

Hope this helps someone,
