Question

I have a auto complete box set up.
however when a user types in the box a list of every single item appears.
Not relating to anything the user is typing in.

What am i doing wrong?

Jquery:

 var availableTags = '@Url.Action("PopSearch", "Home")';
    $("#searchtxt").autocomplete({
        source: availableTags
    });

Controller function:

public ActionResult PopSearch()
    {
        IndustryManager manager = new IndustryManager();
        ProductRangeManager manager2 = new ProductRangeManager();
        ProductCategoryManager manager3 = new ProductCategoryManager();

        IList<Industry> industryList = manager.GetIndustries();
        IList<ProductRange> rangeList = manager2.GetAllProductRanges();
        IList<ProductCategory> categoryList = manager3.GetAllProductCategories();

        var attributes = industryList.Select(x => x.Name)
            .Union(rangeList.Select(x => x.Name))
             .Union(categoryList.Select(x => x.Name)).ToArray();

        return Json(attributes, JsonRequestBehavior.AllowGet);
    }

Check the server request. Probably you have a request to the server something like

http://yoursite.com/Home/PopSearch?term=Something

Where something is what user inputs in the textbox. It means that you need to filter it on the server side and return already filtered data.

public ActionResult PopSearch(string term)
{
    IndustryManager manager = new IndustryManager();
    ProductRangeManager manager2 = new ProductRangeManager();
    ProductCategoryManager manager3 = new ProductCategoryManager();

    IList<Industry> industryList = manager.GetIndustries();
    IList<ProductRange> rangeList = manager2.GetAllProductRanges();
    IList<ProductCategory> categoryList = manager3.GetAllProductCategories();

    var attributes = industryList.Select(x => x.Name)
        .Union(rangeList.Select(x => x.Name))
         .Union(categoryList.Select(x => x.Name)).ToArray();

    var result = attributes.Where(x => x.ToLower().StartWith(term.ToLower()));

    return Json(result, JsonRequestBehavior.AllowGet);
}
