控制器没有返回PartialView？

Question

I have a controller which contains an if statement but it shouldn't matter if it hits the first or second block because they both return the same Type.

[HttpPost]
public ActionResult Descriptions(string partsNo, Details searchValue)
{
    var response = partsNo != null ? _referenceRepository.GetParts(partsNo) : _referenceRepository.SearchValue(searchValue);

    return PartialView(response);
}

View

@model ArrowEngineeringMVC.Models.Details

<script>
    $(document)
        .on("click",
            ".getPartNo",
            function (e) {
                var val = $(this).val();
                $.ajax({
                    url: '/Home/Descriptions',
                    contentType: 'application/json',
                    type: 'POST',
                    data: JSON.stringify({ "partsNo": val }),
                    dataType: 'html'
                })
                    .success(function (result) {
                        $('#descriptionPlace').html(result);
                    })
                    .error(function (xhr, status) {
                        alert(status);
                    });
            })
</script>

@using (Html.BeginForm("Descriptions", "Home", FormMethod.Post))
{
    <div class="topBar">
        @Html.TextBoxFor(m => m.Type)
        <input type="submit" id="submitId" value="submit"/>
    </div>
}

    <div class="leftPanel">
        <button href="javascript:void(0)" id="NumbersButton" value="Number" class="getPartNo">#</button>
        <button href="javascript:void(0)" value="A" class="getPartNo">A</button>
        <button href="javascript:void(0)" value="B" class="getPartNo">B</button>
        <button href="javascript:void(0)" value="C" class="getPartNo">C</button>
    </div>

    <div id="descriptionPlace"></div>

If you click one of the buttons it would hit the first part of the if statement. If you do this then a PartialView is returned and everything works fine, the value from the button is being passed to the controller using AJAX whereas if you do a search it is being passed via the model this is the only difference.

If you do a search it hits the second part of the if statement which doesn't return a partial view it just returns a new view for some reason.

I'm just confused because the variable response returns a List but just contains different values depending on which part of the if statement you hit.

Heres a bit of the referenceRepository just to make it easier to understand:

public List<Parts> SearchValue(Details searchValue)
{
    const string detailsSql = "SELECT [ID], [Description] FROM Table1 WHERE [Type] = {0}";
    string queryDetails = string.Format(detailsSql, searchValue.Type);

    var dbDetails = getConnection().Query<Parts>(queryDetails).ToList();

    return dbDetails;
}

public List<Parts> GetParts(string partNumber)
{
    string partsSql;
    if (partNumber == "Number")
    {
        partsSql = "SELECT [ID], [Description] FROM Table1 WHERE [Part Number]  not like '%[^0-9]%'";
    }
    else
    {
        partsSql = "SELECT [ID], [Description] FROM Table1 WHERE [Part Number] like '{0}%'";
    }

    string queryParts = string.Format(partsSql, partNumber);

    var dbParts = getConnection().Query<Parts>(queryParts).ToList();

    return dbParts;
}

if you want same result as partial view in #descriptionPlace div on submit click.then you can try like this remove form tag.and bind the click event for submit buttons along with those getnumbers buttons..

Not require to post for one value? am i right?

if you want to specific about to load partial view in div or specific area then you have to mention like ajax call.or you can use @Html.Partial or RenderPartial.But your requirement little bit odd. So you can try like this..
