@devendra14321 you can do this using a validation rule.

In the classic designer this would be set on the control itself:

While in the responsive designer this would be done with a rule:

Hope that helps!

@butlerj , thanks. 

It woube be nice to let the user while entering the data instead on clicking the submit button, the form we have got more than 100 controls.

Also, with the data control.. the Today functionality is not wokring as expected. Once user clicks on "Today" it only highlights the date but doesn't populate in the date control field. Is this a bug?

Thanks again.

I agree that field validation is preferable to a submit rule. I’d love to see more examples of calculated/dynamic dates, either in a formula on the control or in as validation rule. For example, in a new responsive form, how would I restrict date selection to a dynamic date of fToday]+3 days? And prevent user from selecting a date prior to that future date?
