Print collection in view

Question

In my project I have got an actionResult method returning a collection of objects like this:

public ActionResult PartNumberManufacturer(string id)
{
    var partNumber = Context.PartNumberTable.Where(x => x.PartNumberId == id); 
    return PartialView("PartNumberView",    partNumber);
}

This is my View

@model IEnumerable<Sales.Model.Part>
@if (Model != null && !string.IsNullOrEmpty(Model.PartNumberManufacturer))
{
    @if (Model.PartNumberManufacturer == "Fr")
    {
        <div>
            <p> This product is developed in france </p>
    }
    @if (@Model.PartNumberManufacturer == "Ger")
    {
        <p> This Product is developed in Germany </p>
    }
}

For some reason when I run my query to search for a partnumber .. it only returns the first found partnumber in the database and it does not query for the others. So after research and research online I found that I need to return a collection and iterate each object in that collection.

How would I iterate my collection abd access each object in the collection??

Thank you

What do you mean? You want iterate the collection in your view? — Sirwan Afifi, Aug 10 '15 at 08:40
Define the `@model classtype` or `@model IEnumerable`(this case) in your view and just iterate like in common c#/VB — blfuentes, Aug 10 '15 at 08:41
use a loop... show your view code, and keep it short, just include the relevant bits of what you have tried already. As it stands, this is just a "how do views work" question, which is way to broad for SO — musefan, Aug 10 '15 at 08:42

The proper way, where you don't have to write the loop yourself, would be to create a DisplayTemplate for your model:

@model PartNumber
@Html.DisplayFor(m => m.id)

Then you can use that DisplayTemplate in your PartNumberView:

@model IEnumerable<PartNumber>
@Html.DisplayForModel()

This will iterate automatically. Of course this may or may not be feasible, depending on what you want your view to look like.

this is making sense .. can it be applied to me edited verion.. please see edited version? – SomuchtoLearn Aug 10 '15 at 08:59
Either put everything from `@if (Model != null ...` in a DisplayTemplate at `~/Views/Shared/DisplayTemplates/Part.cshtml`, or put a `foreach()` in your view. – CodeCaster Aug 10 '15 at 09:00

If you want to iterate the collection inside your view you simply can write this code inside your partial view:

@model IEnumerable<yourModel>
@foreach (var item in Model)
{
    <li>@item.title</li>
}

Update: I think you need something like this:

@model IEnumerable<Sales.Model.Part>
@foreach (var item in Model)
{
    if (Model != null && !string.IsNullOrEmpty(item.PartNumberManufacturer))
    {
        if (item.PartNumberManufacturer == "Fr")
        {
             <p> This product is developed in france </p>
        }
        else if (item.PartNumberManufacturer == "Ger")
        {
             <p> This Product is developed in Germany </p>
        }

    }
}
