As you are not using Html helpers in your form so validation will not work.
You are using pure Html and not the @Html.TextBoxFor() version, so you will need to add custom messages as
public ActionResult CreateEdit(Location obj)
{
if(!ModelState.IsValid)
{
  ModelState.AddModelError("MyForm", "Form is not valid");
// do your work



}




}
And in view
class="alert alert-danger">
  @Html.ValidationMessage("MyForm")

Hi Sachin

In Controller i have done. It's working. How to display errors at Client Side when user clicks on Submit.

Thanks

It simply means you have not used ModelState.IsValid on the Action method

It is the ModelState that collects all the errors and the value as a key-value pair as it is a dictionary.

public ActionResult CreateEdit(Location obj)
{
if(ModelState.IsValid)
{
// do your work
}
}
