how to use kendo ui grid in mvc with GPL version - asp.net-mvc

I am using asp.net mvc4. And for my views designing am using kendo ui GPL version, here am using only javascript of kendo.
<div id="grid" style="width:500px"></div>
<script>
$(document).ready(function () {
$("#grid").kendoGrid({
dataSource: {
transport: {
read: { url: "Movies/Index", dataType: "json" }
},
schema: {
model: {
fields: {
ID:{type:"number"},
Title: { type: "string" },
ReleaseDate: { type: "date" },
Price: { type: "number" },
Genre: { type: "string" }
}
}
},
pageSize: 10,
serverPaging: true,
serverFiltering: true,
serverSorting: true,
},
height:230,
filterable: true,
columnMenu: true,
groupable: true,
sortable: true,
pageable: true,
columns: [
{
field: "ID",
width: 90,
title: "ID"
}, {
field: "Title",
width: 90,
title: "Title"
},
{
field: "Genre",
width: 90,
title: "Genre"
}, {
width: 100,
field: "Price"
}, {
field: "ReleaseDate",
title: "ReleaseDate",
template: '#= kendo.toString(ReleaseDate,"dd MMMM yyyy") #'
}
]
});
});
and in my controller am using json action:
public JsonResult Index()
{
try
{
var ind = db.Movies.Select(a => new Models.Movie
{
ID = a.ID,
Title = a.Title,
Genre = a.Genre,
Price = a.Price,
ReleaseDate = a.ReleaseDate
}).OrderBy(a => a.Title);
return this.Json(ind, JsonRequestBehavior.AllowGet);
}catch(Exception)
{
throw;
}
}
But the problem is data is not fetching into my view. Any help is greatly appreciated.

How to use data from Model to bind as kendo datasource

i have an empty div that i want to initialize into a kendo grid using data from Model..it should be something like the following but i am unable to load data
$("#mapsDiv").kendoGrid({
sortable: true,
dataSource: {
transport: {
read:"/Home/About",
dataType: "odata"
},
pageSize: 5
},
pageable: true,
resizable: true,
columnMenu: true,
scrollable:true,
navigatable: true,
editable: "incell"
});
About.cshtml
#model List<KendoExample.Entities.ShortStudent>
<div class="row">
<div class="col-md-12 table-responsive" id="mapsDiv">
</div>
My Home Controller is as follows
List<ShortStudent> students = new List<ShortStudent>();
ShortStudent student1 = new ShortStudent();
student1.birthdate = new DateTime(1999, 4, 30);
student1.classname = "1B";
student1.firstname = "Fredie";
student1.surname = "Fletcher";
student1.studentid = 1;
ShortStudent student2 = new ShortStudent();
student2.birthdate = new DateTime(2010, 5, 4);
student2.classname = "1B";
student2.firstname = "Lee";
student2.surname = "Hobbs";
student2.studentid = 2;
students.Add(student1);
students.Add(student2);
return View(students);
I have seen examples using json but not odata...
Also, there are examples to use it like
#(Html.Kendo().Scheduler<MeetingViewModel>()
.Name("scheduler")
.Editable(false)
.DataSource(ds => ds
.Custom()
.Batch(true)
.Schema(schema => schema
.Model(m =>
{
m.Id(f => f.MeetingID);
m.Field("title", typeof(string)).DefaultValue("No title").From("Title");
m.Field("start", typeof(DateTime)).From("Start");
m.Field("end", typeof(DateTime)).From("End");
m.Field("description", typeof(string)).From("Description");
m.Field("recurrenceID", typeof(int)).From("RecurrenceID");
m.Field("recurrenceRule", typeof(string)).From("RecurrenceRule");
m.Field("recurrenceException", typeof(string)).From("RecurrenceException");
m.Field("isAllDay", typeof(bool)).From("IsAllDay");
m.Field("startTimezone", typeof(string)).From("StartTimezone");
m.Field("endTimezone", typeof(string)).From("EndTimezone");
}))
.Transport(new {
//the ClientHandlerDescriptor is a special type that allows code rendering as-is (not as a string)
read = new Kendo.Mvc.ClientHandlerDescriptor() {HandlerName = "customRead" }
})
)
)
which i am unable to understand/implement so please ignore this kind of a solution.
Currently i see a grid footer that says (1 - 2 of 4852 items) without any header or content(datarows) on my screen. What am I doing wrong?
UPDATE
var dataSource = new kendo.data.DataSource(
{
transport: {
read: {
url: '#Url.Action("About", "Home")',
contentType: "application/json",
dataType: "json"
}
},
schema: {
model: {
fields: {
firstname: { type: "string" },
surname: { type: "string" },
birthdate: { type: "date" },
classname: { type: "string" }
}
}
},
type: "json",
serverPaging: false,
serverFiltering: true,
serverSorting: false
}
);
$("#mapsDiv")
.kendoGrid(
{
sortable: true,
dataSource: {
transport: {
read: dataSource
},
pageSize: 2
},
pageable: true,
resizable: false,
columnMenu: true,
scrollable:true,
navigatable: true,
editable: "incell",
columns:[{
field: "firstname",
},{
field: "surname",
},{
field: "classname",
},{
field: "age",
}]
});
HomeController
public ActionResult About()
{
....
return View(students);
}
Now the grid with header is there but no data is present..
If i change action to json, it returns plain json on the page
public ActionResult About()
{
....
return Json(students, JsonRequestBehavior.AllowGet);
}
Have you tried adding the fields to the grid?
$("#mapsDiv")
.kendoGrid(
{
sortable: true,
dataSource: {
transport: {
read:"/Home/About",
dataType: "odata"
},
pageSize: 5
},
columns: [
{
field: "classname",
title: "Class Name"
},
{
field: "firstname",
title: "First name"
},
{
field: "surname",
title: "Last name"
}
],
pageable: true,
resizable: true,
columnMenu: true,
scrollable:true,
navigatable: true,
editable: "incell"
});
I just visit demo of telerik. Try following. Hope to help, my friend. Or you can visit this link to refer more: http://demos.telerik.com/kendo-ui/grid/remote-data-binding.
$("#mapsDiv")
.kendoGrid(
{
sortable: true,
dataSource: {
transport: {
read:"/Home/About",
dataType: "odata"
},
pageSize: 5
},
schema: {
model: {
fields: {
studentid: { type: "number" },
birthdate : { type: "date" },
classname : { type: "string" },
firstname : { type: "date" },
surname : { type: "string" }
}
}
},
pageable: true,
resizable: true,
columnMenu: true,
scrollable:true,
navigatable: true,
editable: "incell"
});
So here is what i found what should have been straight forward :)
var values = #Html.Raw(Json.Encode(#Model));
$("#MapDetails")
.kendoGrid(
{
sortable: true,
dataSource: {
data:values,
pageSize: 2
},
pageable: true,
resizable: false,
columnMenu: true,
scrollable:true,
navigatable: true,
editable: "incell",
columns:[{
field: "firstname",
},{
field: "surname",
},{
field: "classname",
},{
field
: "age",
}]
});

},
scrollable: false,
// sortable: true,
// navigatable: true,
// filterable: true,
// scrollable: true,
selectable: true
});
});
</script>
It seems you want to add a command to the grid, The way to add a command as described here is as follows
var grid = $("#jobs-grid").kendoGrid({
dataSource: {
pageSize: 20,
data: #Html.Raw(JsonConvert.SerializeObject(Model.FinishedJobs)),
},
pageable: true,
height: 550,
columns: [
{ field: "JobNumber", title: "JobNumber", width: "140px" },
{ field: "CustomerId", title: "Customer", width: "140px" },
{ field: "Id", title:"Id" },
{ field: "DateCompletition", title:"DateCompletition" },
{ command: { text: "Edit",
click: function(e){
// here you can add your code
}},
title: " ",
width: "180px" }]
}).data("kendoGrid");
You might have a look on the documentation of the kendo grid here
Hope this will help you

Kendo UI Grid update event is not firing

I have Kendo UI inline Grid. It read and populate the grid properly. but when i press edit and changes in any column and press update then update event is not firing.
and it also not calling controller method.
Hope someone can help me point out what I am doing wrong here.
following is my grid binding.
dataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
$.ajax({
type: 'POST',
url: "./GetIngredients",
dataType: "json",
success: function (result) {
options.success(result);
}
});
},
update: function (options) {
$.ajax({
type: 'POST',
url: "./UpdateData",
dataType: "json",
contentType: "application/json; charset=utf-8"
});
},
parameterMap: function (options, operation) {
alert('1');
if (operation !== "read" && options.models) {
alert('2');
return { models: kendo.stringify(options.models) };
}
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "Id",
fields: {
Id: { editable: false, nullable: true },
Division: { type: "string", editable: true, nullable: false },
GroupName: { type: "string", validation: { required: true } },
CategoryName: { type: "string" },
TypeName: { type: "string" },
ItemName: { type: "string" }
}
}
}
});
var grid = $("#grid").kendoGrid(
{
dataSource: dataSource,
height: 430,
scrollable: true,
pageable: true,
navigatable: true,
columns: [
{ field: "Division", title: "Division", width: "80px" },
{ field: "GroupName", title: "Group Name", width: "70px" },
{ field: "CategoryName", title: "Category Name", width: "110px" },
{ field: "TypeName", title: "Type Name", width: "100px" },
{ field: "ItemName", width: "140px" },
{ command: ["edit", "destroy"], title: " ", width: "170px" }],
editable: "inline"
}).data("kendoGrid");
following is the method in Homecontroller.
[HttpPost]
public JsonResult GetIngredients()
{
IngredientData ingredientData = new IngredientData();
ingredientData.Id = 1;
ingredientData.DivisionId = 1;
ingredientData.Division = "Division Abc";
ingredientData.GroupId = 2;
ingredientData.GroupName = "Group -A";
ingredientData.CategoryId = 3;
ingredientData.CategoryName = "Category -D";
ingredientData.FoodTypeId = 4;
ingredientData.TypeName = "Type One";
ingredientData.ItemId = 5;
ingredientData.ItemName = "Item One";
return Json( ingredientData , JsonRequestBehavior.AllowGet);
}
[HttpPost]
public void UpdateData()
{
// logic for update data in database.
}
Did you realize that you have batch set to true? When in batch mode, you have to invoke sync on dataSource or saveChanges in Grid definition.
Try adding a toolbar command for invoking saveChanges as follow:
var grid = $("#grid").kendoGrid({
dataSource: dataSource,
height: 430,
scrollable: true,
pageable: true,
navigatable: true,
toolbar: [ "save" ],
columns: [
{ field: "Division", title: "Division", width: "80px" },
{ field: "GroupName", title: "Group Name", width: "70px" },
{ field: "CategoryName", title: "Category Name", width: "110px" },
{ field: "TypeName", title: "Type Name", width: "100px" },
{ field: "ItemName", width: "140px" },
{ command: ["edit", "destroy"], title: " ", width: "170px" }],
editable: "inline"
}).data("kendoGrid");
or simply remove batch mode.
I have faced same issue. But I have solved using this.
To fire create/delete/update we need to specify schema in dataSource( in schema we should mention atleast what is id field).
schema: {
model: {
id: "StudentID"
}
}
Code:
var dataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
alert("read");
},
create: function (options) {
alert("create");
},
update: function (options) {
alert("update"); },
destroy: function (options) {
alert("destroy"); }
},
schema: {
model: {
id: "StudentID"
}
}
