Can I create a user-friendly data validation message?

Posted on by David_Schrag

I have set the properties of a column with a minimum and maximum value, and that column appears in a form in a model-driven app. If I enter a value outside the allowed range and save the data, I get a pop-up box that says "Decimal Value Out Of Range. A validation error occurred. A decimal value provided is outside of the allowed values," followed by a long set of error codes and diagnostic information.

Is there a way to present a more user-friendly dialog box? Ideally, it would say something like "The value for [column name] must be between [minimum] and [maximum]," but at the very least I'd like to identify which column is causing the error because there are multiple columns on the data entry form.

Re: Can I create a user-friendly data validation message?

Thanks, your response made me take a second look and I found the problem. I am customizing another developer's solution, which uses the same display name for two columns. Column1 appears on the form and Column2 other is used in a business rule or event or something -- I can't immediately find where the workflow lives. When you save the form, the value of Column1 is copied to Column2. I had set the min/max properties on Column2, so the error message was being triggered on the back end rather than on the front end. That must be why I was getting the ugly message. When I changed the properties of the Column1, the validation occurred immediately and I got the desired result.

Min/Max set on Column1:
Min/Max set on Column2 (only):
Thanks for pointing me in the right direction!

Hi @David_Schrag - A Model Driven App Form already includes the functionality you have described out of the box. Could you share a screenshot of your App with the error message? It is not normal to receive an error message like that.
