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);
})
.Update("Editing_Update", "SaveRec")

.Pageable(pageable => pageable
.Refresh(true)
.Input(true)
.Numeric(false)
)
.Resizable(resize => resize.Columns(true))
.Selectable()
.Events(ev => ev.Change("differenceValue"))
)
<script>
$(document).ready(function () {
var gridOutput = $("#OutputCashGrid").data("kendoGrid");
gridOutput.table.bind("keypress", function (e) {
if (e.which !== 0 && e.charCode !== 0 && !e.ctrlKey && !e.metaKey && !e.altKey) {
//get currently navigated cell, this id follows user's navigation
var activeCell = $("#OutputCashGrid_active_cell");
//don't do anything if already editing cell
if (activeCell.hasClass("k-edit-cell")) return;
gridOutput.editCell(activeCell);
var input = activeCell.find("input");
//number datatype editor loses key press character when entering edit
if (input.last().attr('data-type') === 'number') {
var a= input.val(String.fromCharCode(e.keyCode | e.charCode));
var selectedItemRow = gridOutput.dataItem($(e.currentTarget).closest("tr"));
} else {
input.val("");
}
}
});
$("#OutputCashGrid table").on("keydown", "tr", function (e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 13) { //If key is ENTER
//find index of the td element
var activeCell = $("#OutputCashGrid_active_cell");
var tdIndex = $(e.target).closest('td').index();
var tdvalue = $(e.target).closest('td').val();
var cellvalue = activeCell.val();
var row = $(e).closest("tr");
// var model = $("#OutputCashGrid").dataItem(row);
//var difference = selectedItemRow.LocalDifference
//var TotalInternalAmt = selectedItemRow.InternalLocalAmt
//var TotalExternalAmt = selectedItemRow.ExternalLocalAmt
//var updatedDifference = Math.abs(TotalInternalAmt) - Math.abs(TotalExternalAmt)
//selectedItemRow.set("Differnce", updatedDifference)
//get the next row's cell
var nextRow = $(e.target).closest('tr').next();
var nextRowCell = $(nextRow).find('td:eq(' + tdIndex + ')');
//focus the next cell on a different context
setTimeout(function () {
var grid = $("#OutputCashGrid").data("kendoGrid");
grid.current(nextRowCell);
}, 0);
}

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();
}
});
