剣道グリッドの二重読み込みに問題があったため、.autobind(false) を使用して次のようにしました。

var wgrid = $("#WasteGrid").data("kendoGrid"); wgrid.dataSource.Read();

ドキュメント準備機能で。

「Uncaught Type Error: Cannot read property 'datasource' of undefined」というコンソール エラーが表示されるようになりました。

私の質問は、Javascript で剣道グリッドを手動で設定するにはどうすればよいですか?

これが私のコードです（これで十分でない場合は投稿できる_Layout.cshtmlもあります）：

@model IEnumerable<OPS.Models.LabourSchedule>

@{
ViewBag.Title = "Ham";
Layout = "~/Views/Shared/_Layout.cshtml";
ViewBag.DatePageType = "LabourEntry";
}

<script>

$(document).ready(function () {

//reads and populates the waste grid
var wgrid = $("#WasteGrid").data("kendoGrid");
wgrid.dataSource.Read();

});

//waste form update parameters
function Update_Data() {
return {
CurDate: kendo.toString($("#datepicker").data("kendoDatePicker").value(), "yyyy-MM-dd")
};
}

//waste form read parameters
function Read_Data() {
return {
LineName: "Ham",
CurDate: kendo.toString($("#datepicker").data("kendoDatePicker").value(), "yyyy-MM-dd"),
ShiftName: @(Session["currentShift"]) + ""
};
}

</script>

js をグリッドの後に移動し、同じエラーが発生した後、スクリプトである可能性がありますか? これが私の_Layoutコードです...
