Posted on by cbroy_22

Need a help. In my app user is asking for option of a textbox where they can only be able to type 0, 1 or NA or it can be left blank. Initially we created combo box and restricted but user wants to type in. Please let me know if this can be acheived in PowerApps.

Thanks

["",0,1,"N/A"]

In the items property of a dropdown control.

Or [0,1,"N/A"] As items in a radio control with the default property left blank

Having to type in and being told they are wrong or trying to guess the right answer is not a good user experience. What if they type in "one"?

But that's for dropdown, but they do not want dropdown, can this be done in textbox? I believe ISMatch will work but can't exactly figure tout the syntax.

Hi @cbroy_22,

Do you want to force users only input 0, 1, NA or leave blank in the TextInput control?

If so, please set the OnChange property of the TextInput as below:

If( !(IsMatch( TextInput19.Text, "^[0-1]*$|(NA)" )), Notify( "Plese input valid characters or numbers!", NotificationType.Error ) )
