如何在KendoUI中获取选定的行值

Question

我有一个kendoUI网格.

                @(Html.Kendo().Grid<EntityVM>()
                    .Name("EntitesGrid")
                                .HtmlAttributes(new { style = "height:750px;width:100%;scrollbar-face-color: #eff7fc;" })
                    .Columns(columns =>
                    {
                        columns.Bound(e => e.Id).Hidden().IncludeInMenu(false);
                        columns.Bound(e => e.EntityVersionId).Hidden().IncludeInMenu(false);
                        columns.Bound(e => e.Name).Width("70%").Title("Entity Name");
                        columns.Bound(e => e.EIN).Width("30%");
                    })
        .ToolBar(toolBar => toolBar.Template("<a class='k-button k-button-icontext k-grid-add' id='addEntity'><span class='k-icon k-add'></span>Entity</a>" +
             "<a class='k-button k-button-icontext' id='editEntity'><span class='k-icon k-edit'></span>Edit</a>"))
                    .DataSource(dataSource => dataSource
                    .Ajax().ServerOperation(false)
                    .Model(model => model.Id(e => e.Id))
                    .Read(read => read.Action("GetEntities", "Entity", new { projectId = Request.QueryString[DataKeyNameConstants.ProjectId] })))
                    .Sortable()
                    .Scrollable()
                    .Filterable()
                    .Resizable(resize => resize.Columns(true))
                    .Reorderable(reorder => reorder.Columns(true))
                    .ColumnMenu()
                    .Selectable(s => s.Mode(GridSelectionMode.Multiple))
                    .Events(events => events.Change("entSelChange"))
            )

现在,我需要从选定的行中获取EntityVersionId的值.但不知道该怎么做.

这是我的javascript函数

$("#editEntity").click(function () {

    var entityGrid = $("#EntitesGrid").data("kendoGrid");

    // what should I do from here
});

更新:添加代码以循环所有行.

function loadPreviousEntityVersion() {

    alert("sdfsdfsdf");
    var entityGrid = $("#EntitesGrid").data("kendoGrid");
    var data = entityGrid.dataSource.data();

    for(var i = 0; i<data.length; i++) {
        var currentDataItem = data[i];
        alert(dataItem.EntityVersionId);

    }
}

一种方法是使用网格select() 和dataItem()方法.

在单选案例中,select()将返回可传递给的单行dataItem()

var entityGrid = $("#EntitesGrid").data("kendoGrid");
var selectedItem = entityGrid.dataItem(entityGrid.select());
// selectedItem has EntityVersionId and the rest of your model

对于多行选择select()将返回一个行数组.然后,您可以遍历数组,并且可以将各个行传递到网格中dataItem().

var entityGrid = $("#EntitesGrid").data("kendoGrid");
var rows = entityGrid.select();
rows.each(function(index, row) {
  var selectedItem = entityGrid.dataItem(row);
  // selectedItem has EntityVersionId and the rest of your model
});

有更好的方法.我在使用kendo angularJS指令和网格没有ID的页面中使用它...

change: function (e) {
   var selectedDataItem = e != null ? e.sender.dataItem(e.sender.select()) : null;
}
