We are seeing an issue where the Change event for Grid is firing as if it was the Databind event. We get a console log event on load and when we filter the grid to cause another bind, but not when I click select on a row. I want to redirect to a details page for that row when the user clicks.

<div class="ci-body-grid">

@(Html.Kendo().Grid<OrderViewModel>()

.Name("gridMain")

.Columns(columns => {

columns.Bound(e => e.OrderID).Filterable(false);

columns.Bound(e => e.Freight);

columns.Bound(e => e.OrderDate).Width(120).Format("{0:MM/dd/yyyy}");

columns.Bound(e => e.ShipName).Width(260).Filterable(filterable => filterable.Cell(cell => cell.Operator("contains").ShowOperators(false)));

columns.Bound(e => e.ShipCity).Width(150);

})

.Excel(excel => {

excel.AllPages(true);

excel.FileName("Users.xlsx");

})

.ToolBar(toolbar => { toolbar.ClientTemplateId("tmpGridToolbar"); })

.Pageable(pageable => pageable.Refresh(true).Numeric(false).PreviousNext(false))

.Selectable(selectable => selectable.Mode(GridSelectionMode.Single).Type(GridSelectionType.Cell))

.Navigatable()

.Mobile()

.Resizable(resize => resize.Columns(true))

.ColumnMenu()

.Sortable()

.Scrollable(scrollable => scrollable.Virtual(true))

.Filterable(filterable => filterable.Mode(GridFilterMode.Row))

.DataSource(dataSource => dataSource

.Custom()

.Events(events => events.Change("gridMain_OnChange").Error("error_handler"))

.Type("odata")

.Transport(transport =>

transport.Read(read => read.Url("https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"))

)

.PageSize(100)

.ServerPaging(true)

.ServerSorting(true)

.ServerFiltering(true)

))

</div>

<script id="tmpGridToolbar" type="text/x-kendo-template">

<span class="ci-header-grid">Users</span>

<div class="k-float-right k-display-inline-block">

@(Html.Kendo().Button().Name("btnExport").Icon("file-excel").Content("Export").Events(evt => evt.Click("exportGrid")).ToClientTemplate())

</div>

</script>

@section Scripts {

<script>

function exportGrid() {

$("#gridMain").data("kendoGrid").saveAsExcel();

}

function resizeGrid() {

$("#gridMain").data("kendoGrid").resize();

}

$(window).resize(function () {

resizeGrid();

});

function gridMain_OnChange(arg) {

var test = "";

console.log(this);

//var selected = $.map(this.select(), function (item) {

// return $(item).text();

//});

//console.log("Selected: " + selected.length + " item(s), [" + selected.join(", ") + "]");

}

</script>

}

Hi Ari,

In the provided Grid definition the gridMain_OnChange function is executed when the change event of the DataSource is triggered. Define the Grid as follows and the change event should be fired as expected:

@(Html.Kendo().Grid<OrderViewModel>()
    .Name("gridMain")
    .Columns(columns =>
            {
        columns.Bound(e => e.OrderID).Filterable(false);
        columns.Bound(e => e.Freight);
        columns.Bound(e => e.OrderDate).Width(120).Format("{0:MM/dd/yyyy}");
        columns.Bound(e => e.ShipName).Width(260).Filterable(filterable => filterable.Cell(cell => cell.Operator("contains").ShowOperators(false)));
        columns.Bound(e => e.ShipCity).Width(150);
    })
    .Excel(excel =>
            {
        excel.AllPages(true);
        excel.FileName("Users.xlsx");
    })
    .ToolBar(toolbar => { toolbar.ClientTemplateId("tmpGridToolbar"); })
    .Pageable(pageable => pageable.Refresh(true).Numeric(false).PreviousNext(false))
    .Selectable(selectable => selectable.Mode(GridSelectionMode.Single).Type(GridSelectionType.Cell))
    .Navigatable()
    .Mobile()
    .Resizable(resize => resize.Columns(true))
    .ColumnMenu()
    .Sortable()
    .Scrollable(scrollable => scrollable.Virtual(true))
    .Filterable(filterable => filterable.Mode(GridFilterMode.Row))
    .Events(events => events.Change("gridMain_OnChange"))
    .DataSource(dataSource => dataSource
        .Custom()
        .Type("odata")
        .Events(events => events.Error("error_handler"))
        .Transport(transport =>
            transport.Read(read => read.Url("https://demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"))
        )
        .PageSize(100)
        .ServerPaging(true)
        .ServerSorting(true)
        .ServerFiltering(true))
    )

Let me know if the suggested change resolves the issue.
