We are implementing [validation](https://www.mindstick.com/articles/12234/validation-using-data-annotation-using-entity-framework) in [MVC](https://www.mindstick.com/forum/155803/define-cache-profile-in-mvc) is by using data annotations. Data annotations are nothing but attributes which can be applied on model properties. For example, we have a simple Student class with a property StudentFullName.This StudentFullName property is tagged with a Required data annotation attribute. In other words if this model is not provided Student FullName, it will not accept it.\
\

```
public class Student{    [Required(ErrorMessage=" Student FullName is required")]    public string StudentFullName    {        set;        get;    } }  
```

\
For display of validation error message we need to use the ValidateMessageFor method which belongs to the Html helper class.\

```
@using (Html.BeginForm("StudentFullName", "Home", FormMethod.Post)){ @Html.TextBoxFor(m => m. StudentFullName)@Html.ValidationMessageFor(m => m. StudentFullName).....}
```

\
Later in the controller we can check if the model is proper or not by using the ModelState.IsValid property and accordingly we can take actions.\

```
public ActionResult StudentFullName(Student obj){    if (ModelState.IsValid)    {        obj.Save();        return View("Save Sucessfully");    }    else    {        return View("Student");    }}
```
