We are using SharePoint 2013 and have a custom list in which one of the fields is a mandatory date/time field. When using the default "New" form, if I don't add any date and click the Save button, the form looks like it is submitted and then comes back with some red text indicating that I need a value for my date/time field. If I simply create a new custom "New" form, and then click on the Save button without adding my date/time value, I get a black (not red) validation error. A couple things are going on here. The error is displayed BEFORE any submit happens, unlike when using the default New form. The validation message is different and is listed in black rather than red. For other mandatory fields, the form does get submitted and then displays the validation error in red, although it is a different validation error message than when using the default New form.
I don't care that the text is different, but it is an issue for us that the text is not in red. Does anyone know why this is happening?
