We will have to edit the following code:


We will pass our composite primary key to edit, details and delete functions
        @Html.ActionLink("Edit", "Edit", new { Styleid=item.style_id, ColorId = item.colour_id }) |
            @Html.ActionLink("Details", "Details", new {Styleid=item.style_id, ColorId = item.colour_id}) |
            @Html.ActionLink("Delete", "Delete", new { Styleid=item.style_id, ColorId = item.colour_id })


 Modify TestController methods - ensure they are receiving StyleId and ColorId
For instance Edit method will look like this

        public ActionResult Edit(int StyleId = 0, int ColorId = 0)
        {
            TestCompositePrimary testcompositeprimary = db.TestCompositePrimaries.Find(StyleId,ColorId);
            if (testcompositeprimary == null)
            {
                return HttpNotFound();
            }
            ViewBag.colour_id = new SelectList(db.ColorMasters, "ColourId", "ColourName", testcompositeprimary.colour_id);
            ViewBag.style_id = new SelectList(db.StyleMasters, "StyleId", "StyleName", testcompositeprimary.style_id);
            return View(testcompositeprimary);
        }
 Run the program - go to http://localhost:50566/Test and try to edit or delete some records - this time it will work perfectly.
