Kendo Ui在ASP.NET Core MVC中无法获取DataValueField值

问题描述

我正在使用kendo多列下拉列表,但似乎无法从DatValueField中获取值,我正在使用该值来获取所选人员的ID,以便将其存储在另一个表中。>

如果有人可以告诉我如何在bootstrap中复制同一内容,请执行telerik并不是我唯一的答案,而是避免使用tbh

<form asp-action="LinkToCase" method="post" asp-controller="MISObjects">

 <div class="row">
    <div class="col-md-12">
        <div class="card card-success">

        <div class="card-header" style="background-color:#1e3f5a;color:white">
            <h3 class="card-title">Search and Tag</h3>
        </div>
        <div class="card-body">

            <div class="col-md-12">
                <div class="input-group">
                    <select id="searchOptions" name="searchOptions" style="background-color: #1e3f5a; color: white; width: 140px; height: 45px">
                        <option selected value="1">Poi</option>
                        <option selected value="1">Vessel</option>
                    </select>


                    @(Html.Kendo().multicolumnComboBox()
                        .Name("tagItem")
                        .DataTextField("name")
                        .DataValueField("SearchId")
                        .Filter("contains")
                        .FilterFields(new string[] { "name","ContactTitle","CompanyName","Country" })
                        .Columns(columns =>
                        {
                            columns.Add().Field("name").Title("Contact Name").Width("200px");
                            columns.Add().Field("dob").Title("Date Of Brith").Width("200px");

                        })
                        .FooterTemplate("Total #: instance.dataSource.total() # items found")
                        .HtmlAttributes(new { style = "width:80%;" })
                        .Height(400)
                        .DataSource(source => source
                            .Custom()
                            .Transport(transport => transport
                                .Read(read =>
                                {
                                    read.Action("SearchQuery","MISObjects")
                                        .Data("onAdditionalData");
                                }))
                        )
                        )
                    <button type="submit" class="btn-primary" value="Link To Case" style=" background-color:#1e3f5a;color:white">Link To Case</button>

                 </div>
       </div>
   </div>
</form>

kendo comBox调用功能

[HttpPost]
public IActionResult LinkToCase(int SearchId,string updateInfo,int tagItem,string sesearchOptionsr,IFormCollection formItems) {
    
      Int32.TryParse(TempData.Peek("CaseId").ToString(),out int resultCaseId);
      var test = formItems;
        POI newPoi = new POI();
        newPoi =  _context.Pois.SingleOrDefault(w => w.Id == SearchId);

        newPoi.MISObjectId = resultCaseId;

        _context.Pois.Add(newPoi);

        _toast.AddSuccesstoastMessage(
            $"You have linked {newPoi.FirstName} {newPoi.LastName} to case {resultCaseId:d8}");

        return RedirectToAction("Edit",new { id = resultCaseId });

    }
    private IEnumerable<Searchviewmodel> GetSearchRecords() {
        return _context.Pois.Where(w => w.isActive == true && w.isDeleted == false).Select(person =>
             new Searchviewmodel {
                 SearchId = person.Id,Name = person.FirstName + "  " + person.LastName,dob = person.dob
             }).ToList();

  }

但是即使当我检查SearchId时,即使我将其设置为int,它也还是空白的,因为我在路上时放了一张支持票,但看到它们是kendo标签,因此认为也可以在这里尝试

您将在下面看到,在表单收集项中找不到该值。

解决方法

如果我正确地阅读了代码,对我来说,您想要的SearchId值应该已经在控制器方法的tagItem int参数中,因为这是表单中MultiColumnComboBox的名称。该MultiColumnComboBox绑定到一个具有SearchId作为值字段的列表,该列表是不同的,并且不会在提交时发回。
