model driven apps: business rules to avoid the insert of numbers for a field of an entity

I have a field of an entity where I would like to avoid the insert of number 1,2,3,4,5,6,7,8,9,0.

I used 10 different business rules in OR with this format:

If Name contains "1"

Then Show the error message "You cannot enter numbers"


If Name contains "2"

Then Show the error message "You cannot enter numbers"



I would like to understand if exist a regular expression for this scenario.

You can reference this doc shows to test:





Hope this could be helpful.


Best Regards.


Check out the input mask control if that can address the requirement. 


You can use ClientAPIs  which would enble use of JS regular expressions.


Depending upon what is your end goal and complexity/custom US need , PowerApps component framework is a great alternative. See some community demo controls here.
