Question

我需要从搜索按钮填充Kendo网格。我写了个人ID，我应该在网格中获取其他信息，但在文本框中写入ID并点击搜索后，我得到了

“服务器无法处理请求.---＆gt;程序或功能 'PROS_CRA_PUBLIC_GET_DOCUMENT_LIST_BY_PN'需要参数'@PN'，这是没有提供的。“

控制器

public ActionResult Search(string personalID, [DataSourceRequest]DataSourceRequest request)
    {



        var serviceclient = new PersonalInfoServiceClient();
        DataSourceResult result = null;
        try
        {
            var items = serviceclient.GetRegistryInfoForPerson(personalID);
            result = items.ToDataSourceResult(request);

        }
        catch 
        {
            throw;
        }
        finally
        {
            serviceclient.Close();
        }

        return Json(result, JsonRequestBehavior.AllowGet);

    }

     <p> personal number: <input type="text" name="Searchtext" id="SearchString" /> <input type="submit" value="search" name="btnSearch" id="btnSearch" /></p>

Answer 1

您没有传递 personalID 。

添加一个javascript函数，负责传递控制器函数所需的数据，例如

function additionalData() {
    return {
        personalID: '@Model.personalID'
    };
}

然后更改网格的DataSource以使用javascript函数

.DataSource(dataSource => dataSource.Ajax().ServerOperation(false)
    .Read(read => read.Action("Search", "Main")                                                                                      
    .Data("additionalData"))
)

还要确保

[DataSourceRequest] DataSourceRequest请求

参数首先放在控制器功能中，例如

public ActionResult Search([DataSourceRequest]DataSourceRequest request
                           , string personalID)

还要确保使用返回的对象的属性绑定网格的列（在您的情况下为PersonalIDCheckerMvCKendo.Models.PersInfo）。例如

.Columns(columns =>
     {
          columns.Bound(pi => pi.Name);
          columns.Bound(pi => pi.Surname);
          // Some other columns.                                    
     })

*的更新

为了帮助您，我添加了一个工作网格示例。这是我的网格

@(Html.Kendo().Grid<ClientSearchResult>() .Name("Grid") .HtmlAttributes(new {style = "height:400px; cursor:pointer"}) .DataSource(dataSource => dataSource.Ajax().ServerOperation(false) .Read(read => read.Action("RefreshGrid", "Client") .Data("additionalData")) .PageSize(20) ) .Columns(columns => { columns.Bound(c => c.ClientId); columns.Bound(c => c.Name); columns.Bound(c => c.PolicyNumber); columns.Bound(c => c.ClaimNumber); columns.Bound(c => c.Status); columns.Bound(c => c.IsCompany); }) .Pageable(page => page.Enabled(true).PageSizes(new[] {10, 20, 30, 40})) .Sortable(sorting => sorting.SortMode(GridSortMode.SingleColumn)) .Scrollable() .Selectable(selectable => selectable.Mode(GridSelectionMode.Single)) .Events(events => events.Change("grid_selected")) )

我的javascript函数

function additionalData() { return { cellNumber: '@Model.CellNumber', name: '@Model.Name', policyNumber: '@Model.PolicyNumber', claimNumber: '@Model.ClaimNumber', brokerCode: '@Model.BrokerCode', brokerName: '@Model.BrokerName' }; }

和我的控制器功能

public ActionResult RefreshGrid([DataSourceRequest] DataSourceRequest request , string cellNumber, string name , string policyNumber, string claimNumber , string brokerCode, string brokerName) { if (cellNumber == string.Empty && name == string.Empty && policyNumber == string.Empty && claimNumber == string.Empty && brokerCode == string.Empty && brokerName == string.Empty) return Json(new List<ClientSearchResult>()); else { List<ClientSearchResult> searchResult = ClientMaintenance.ClientSearch(cellNumber, name, policyNumber, claimNumber, brokerCode, brokerName).ToList(); var result = searchResult.ToDataSourceResult(request); return Json(result); } }

Answer 2

我修好了

将控制器更改为：

    public ActionResult Search([DataSourceRequest]DataSourceRequest request, string searchString)
    {



        var serviceclient = new PersonalInfoServiceClient();
        DataSourceResult result = null;
        if (!String.IsNullOrEmpty(searchString))
        {
            try
            {
                var items = serviceclient.GetRegistryInfoForPerson(searchString);
                result = items.ToDataSourceResult(request);

            }

            catch
            {
                throw;
            }

            finally
            {
                serviceclient.Close();
            }
        }

        return Json(result, JsonRequestBehavior.AllowGet);

    }

查看：

文本框：

@Html.TextBox("SearchString")

功能：

<script type="text/javascript">
$(document).ready(function(){
    $("#btnSearch").click(function (e) {
     $.ajax({
            url: '@Url.Action("Search","Main")',
            type: 'POST',
            dataType: "json",
            success: function (result) {    

                $("#Grid").data("kendoGrid").dataSource.read();
                $("#Grid").data("kendoGrid").refresh();
                e.preventDefault();
            }
