Answer 1

This should work:

@using (Html.BeginForm("YourActionName", "YourControllerName","Upload", FormMethod.Post)) {
    @Html.ValidationSummary(false);
    <p>
        Name: @Html.TextBoxFor(m => m.Name)
    </p>
    <p>
        Age: @Html.TextBoxFor(m => m.Age)
    </p>
    <input type="submit" value="Sign In" />
    <h6>SignIn</h6>
}

...Assuming that you have validation attributes (eg [Required] ) on the properties on the model.

Notice that the validation summary is inside the Html.BeginForm() block.

Also notice the TextboxFor syntax (rather than Textbox ) which makes sure that your properties are strongly typed.

Also, make sure you have these settings in the appsettings section of your web.config file:

<add key="ClientValidationEnabled" value="true"></add>
<add key="UnobtrusiveJavaScriptEnabled" value="true"></add>
