The NumericTextBox renders two input elements. In a Grid inline editing scenario: https://demos.telerik.com/aspnet-mvc/grid/editing-inline one of inputs of the NumericTextBox editor does not render a title and there is no label for the inputs. This causes an error for missing form element label in Html static analysis (Wave).
One way for this to be avoided could be using aria-labelledby attribute instead of title. The same aria-labelledby value will be assigned to both inputs pointing to a span or div that contains the input value. This way both inputs will have label and won't trigger the missing label error.
