$(document).ready(function () {
dataSource = new kendo.data.DataSource({
transport:
{
read:
{
url: "/Student/StudentGrid",
contentType: "application/json; charset=utf-8",
dataType: "json",
type: "GET"
},
update:
{
url: "#Url.Action("EditStudentDetails")",
contentType: "application/json;charset=utf-8",
dataType: "json",
type: "POST"
},
parameterMap: function (options, operation) {
if (operation != "read" && options) {
if (operation != "destroy") {
return JSON.stringify({
studentViewModel: options
});
}
else if (operation == "destroy") {
return JSON.stringify({
id: options.Id
});
}
}
}
},
parse: function (test) {
if (test.success) {
if (test.type != "read") {
alert(test.message);
$("#grid").data("kendoGrid").dataSource.read();
}
return test.data;
}
else {
alert(test.message);
return [];
}
}
})
$("#grid").kendoGrid({
dataSource: dataSource,
filterable: true,
toolbar: ["create"],
sortable: true,
pageable: true,
columns: [
{
field: "Id",
width: 120,
visible: false
},
{
field: "Name",
title: "Student Name",
editor: AutocompleteName,
width: 180
},
{

width: 200,
template: "#=CourseName#"
},

}
],
editable: "inline"
});

Answer 1

Is any of your cell text has HTML tags like "<" or ">", remove them and click on update and check the update event fire.
