CodePudding user response：
Probably You should do This:
@Html.TextBoxFor(model => model.Price, new { type = number } )
If You are using MVC- 1.5 or higher you dont need to use htmlAttributes, but you should change the type of input value for the textBoxFor cause its always a string that you are passing to your int parameter
CodePudding user response：
There is a bug in the code. The view uses a model
@model PharmaProj.Models.Product
but you submit Product from view to the action where Purchace is an input parameter
[HttpPost]
public ActionResult PurchaseProd(Purchase po)
you have to decide what to use Product or Purchase
