MVC5 Validation Errors in Razor View - asp.net-mvc

Question

I am using MVC5 and having problem displaying the validation errors of an object both in the Validation Summary section and the individual validation messages for each control.
Lets put aside client validation for the moment although we have ENABLED IT in the web config and included the js files.
If a model that is invalid is passed to a view that has in place a Validation Summary (setting excludePropertyErrors to false) and for each control there is a #Html.ValidationMessageFor(model => model.Summary, "", new { #class = "text-danger" }), shoudn't all these display the Validation errors in the object when the page loads.
We checked the object and the framwork knows it is invlaid (ModelState.IsValid is definitely false) and the errors collection contains several validation errors
(System.Data.Entity.Validation.DbValidationError) but none of them show up neither in the ValidationSummary or the ValidationMessage for the individual controls when the page loads.
Currently I am getting he validation errors manually by context.Entry(prop).GetValidationResult().ValidationErrors.ToList(); and passing it to the Viewbag and iterate over them in the view to display them. Seems crazy!
P.S. The main View is composed of several partial views in which the controls are and the Vaidationsummary is in the Main containing view.
public async Task<ActionResult> GetProduct(id)
{
var product= await context.Products.FindAsync(id);
return View(product);
}
As I mentioned , there are NO VALIDATION MESSAGES ANYWHERE. If we turn off client side validation the input control html is
<input class="form-control text-box single-line valid" id="Price" name="Price" style="font-weight:bold" type="text" value="" aria-invalid="false">
As you can see the value is empty BUT it says it is valid even though the field is a required field marked so via DataAnnotations and the Model is INVALID and includes validation error that Price field is required!
Here is the code:
<div class="form-group">
#Html.LabelFor(m => m.Price, new { #class = "col-sm-3 control-label" })
<div class="col-sm-5">
#Html.EditorFor(model => model.Price, new { htmlAttributes = new { #class = "form-control", style = "font-weight:bold" } })
#Html.ValidationMessageFor(model => model.Price, "", new { #class = "text-danger" })
</div>
</div>
And this is the generated html with client side validation enabled :
<input class="form-control text-box single-line" data-val="true" data-val-number="The field Price must be a number." data-val-required="The Price field is required." id="Price" name="Price" style="font-weight:bold" type="text" value="">
Would greatly appreciate any assistance.
