根据kendo grid asp.net mvc中的另一个单元格值更新单元格值

new*_*bie 4 jquery inline-editing asp.net-mvc-4 kendo-grid kendo-asp.net-mvc

我已经为这个问题苦苦挣扎了两天,非常感谢任何帮助。我有一个剑道网格,其中我给了网格 excel 一样的功能,即在点击输入时,可编辑的列被突出显示,我可以输入值,并在选项卡上移动到下一个单元格。我有一个名为 external amount 的列是可编辑的,即用户在单元格中输入值,下一列是差异,每当用户在外部金额列中输入一个值并点击回车时,就应该计算该差异。

差异-InternalLocalAmt-ExternallocalAmt。InternalLocalAmt 已填充且不可编辑。

代码片段:

@(Html.Kendo().Grid(Model)
    .Name("OutputCashGrid")
    .Columns(columns =>
    {

        columns.Bound(p => p.InternalLocalAmt).Width(130);
        columns.Bound(p => p.ExternalLocalAmt).Width(130);
  columns.Bound(p => p.LocalDifference).Title("Difference").Width(130).Format("{0:N}").HtmlAttributes(new{id="DifferenceVal"});
 })
  .Sortable()
     .ColumnMenu()
     .Scrollable(scr => scr.Height(430))
     .Filterable()
     .Navigatable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(50)
        .ServerOperation(false)
             .Batch(true) // Enable batch updates.
                       .Model(model =>
                            {
                                model.Id(p => p.OutputcashID); // Specify the property which is the unique identifier of the model.
                                //model.Field(p => p.OutputcashID).Editable(false); // Make the ProductID property not editable.
                                model.Field(p => p.OutputcashID).Editable(false);
                                model.Field(p => p.Level1).Editable(false);
                                model.Field(p => p.TotalRecitems).Editable(false);
                                model.Field(p => p.TotalReconcilingItems).Editable(false);
                                model.Field(p => p.AsOfDate).Editable(false);
                                model.Field(p => p.InternalLocalAmt).Editable(false);

                            })

图片中ExternalLocalAmt是可编辑的,我想更新差异

我附上了一个屏幕截图来显示网格。

我看到你已经发布了你的问题的答案,但我自己最近也在为类似的事情苦苦挣扎,并想出了我认为更有效的解决方案。

Calculations您可以先将change事件附加到数据源,然后访问行模型中已更改并根据需要更新的项目,而不是更新网格数据源中的所有项目(使用您的函数)。

例如:

var gridOutput = $("#OutputCashGrid").data("kendoGrid");
gridOutput.dataSource.bind("change", function(e) {
   // checks to see if the action is a change and the column being changed is what is expected
   if (e.action === "itemchange" && e.field === "ExternalLocalAmount") {           
       // here you can access model items using e.items[0].modelName;
       e.items[0].Difference = e.items[0].InternalLocalAmount - e.items[0].ExternalLocalAmount;
       // finally, refresh the grid to show the changes
       gridOutput.refresh();
   }
});
