如何在剑道UI网格asp.net mvc中刷新单列

Question

以下是我将数据加载到剑道网格的代码：

@(Html.Kendo().Grid(Model)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.CountryName);
        columns.Bound(p => p.CountryCode);
        columns.Bound(p => p.CountryCodeLength);
        columns.Bound(p => p.CurrencyString);
        columns.Bound(p => p.CountryISOName);
    })
    .Pageable(p =>
    {
        p.Enabled(true);
        p.PageSizes(new int[] { 10, 20, 30, 40, 50 });
    })
    .Sortable()
    .Selectable()
    .Groupable()
    .Scrollable() 
    .Filterable()    
    .DataSource(dataSource => dataSource        
        .Ajax()
        .Model(model => model.Id(p => p.ID))
        .Read(read => read.Action("Country_Read", "Country")).PageSize(10)
     )
     .Events(events => events.Change("GridChange"))
     .ToolBar(toolbar =>
     {
        toolbar.Template(
            @<text>
                <div id="Toolbar">
                    <a id="Add" href="@Url.Action("Create", "Country")" title="Add New Record"></a>
                    <a id="Edit" title="Edit Selected Record"></a>
                    <a id="Delete" title="Delete Selected Record"></a>
                </div>
            </text>);
     })
      )

如何定期在10-15秒内刷新列CountryCodeLength
我尝试刷新整个网格，但我有一些弹出窗口要在同一网格内打开。因此，在使用弹出窗口刷新整个网格时，弹出窗口将丢失
请告诉我如何刷新单个列？这是我用来刷新整个网格的代码：

$(document).ready(function()
{
    var refreshId = setInterval( function() {
                //GET YOUR GRID REFERENCE
        var grid = $("#Grid").data("kendoGrid");
                grid.dataSource.read();

    }, 5000);
});

Answer 1

var gridData  = $("#Grid").data("kendoGrid").dataSource;
var data      = gridData.at(0);//data at 0 Location
data.set("CountryCodeLength", 20);//set the value here

您可以使用轮询脚本来刷新值

Answer 2

var MyGrid  = $("#MyGrid").data("kendoGrid");
var selectedItem = MyGrid.dataItem(MyGrid.select());
selectedItem.set("CountryCodeLength", 10);
MyGrid.tbody.find("tr[data-uid="" + selectedItem.uid + ""]").addClass("k-state-selected");
