I am using partialview in modal form. In this form there is a select2 option list which working fine. But when press submit button, required fields as per model are not validating i.e. not showing error.
I have used lots option from internet, but failed to get the desired result.
When we remove the select2 field from partialview, it’s working fine.

Behind all these scenaraios, I have changed my button type 'button' to input type 'submit' then validation worked fine.
But after that another proble produced. From controller,
return PartialView("_Customer", collection); caused existing layout null.
In Index view, call the partialview, and use modal form validation after using select2. You can refer to it.
HomeController:
Index view:
Cust_Master:
_IndexPartial:
Result:
