Uncaught TypeError: e.slice is not a function on data fetch

Hi!

I'm trying to make an ajax call to my controller function.
To get all the data that currently are in a grid's datasource.
Instead of calling directly to the grid's datasource.data() which only returns me the current grid page.

I go about this by instantiating a new kendo datasource.
But everything i try, yields "Uncaught TypeError: e.slice is not a function"

Thanks in advance.

public JsonResult ReadTimeRegistrationAjax([DataSourceRequest] DataSourceRequest request)

{

var dataSourceResult = getStuff().ToList();

return Json(dataSourceResult.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

var grid = $("#GridTimeRegistrations").data("kendoGrid");

var dataurl = grid.dataSource.transport.options.read.url;

var dataSource = new kendo.data.DataSource({

transport: {

read: {

url: dataurl,

dataType: 'json'

}

},

});

dataSource.fetch(function() {

var data = dataSource.data();

console.log(data);

}

Reorder problem in kendoTilesLayout

I have an issue and I need someone to see what I'm doing wrong...

I tried to use several times "reorder". I simplify the test to this :

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

A

</script>

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

B

</script>

$("#home-super-container").kendoTileLayout({

containers: [{

colSpan: 1,

rowSpan: 1,

header: {

text: "Barcelona"

},

bodyTemplate: kendo.template($("#barcelona").html())

}, {

colSpan: 1,

rowSpan: 1,

header: {

text: "Sofia"

},

bodyTemplate: kendo.template($("#sofia").html())

}],

columns: 2,

columnsWidth: 285,

rowsHeight: 285,

reorderable: true,

reorder: function (e) {

console.log(e.newIndex, e.oldIndex);

}

});

The console.log indicates (0 0), it should be (0 1) or (1 0)...

Change grid column template with button click

Hi,

I have a kendo toolbar with multiple dropdowns and checkboxes to filter my datasource. What I want is when I submit my filter selections, if a spesific checkbox is checked, then datetime column of the grid will have this template:

"#= kendo.toString(kendo.parseDate(dates), 'dd/MM/yyyy') #"

If the checkbox not checked (or the page is just loaded with empty checkbox in default scenario) the column will have:

"#= kendo.toString(kendo.parseDate(dates), 'dd/MM/yyyy HH:mm') #"

as template.

I tried conditioning inside of grid but I didn't manage to obtain checkbox value. I tried writing a function outside the grid function but when I refresh grid data with:

var grid = $("#grid").data("kendoGrid");
grid.dataSource.data(reportData);

it only refresh the data inside grid, that does not trigger the template function.

How can I change the column template while refreshing the data according to that checkboxs value?

Selecting row in grid causes page to scroll

When I have a grid that extends below the visible area of the page, clicking on a row causes the page to scroll upward by some arbitrary amount. My attempt to prevent this in the grid change handler is not successful, because the scroll is instantaneous, and happens before the handler is called. I can scroll the page back down within the handler, but this causes a very noticeable 'jump' when a row is clicked. It appears this only happens in Chrome.

I have two questions:

1. why does the page scroll at all when a row is clicked?
2. how can i PREVENT the scrolling entirely, instead of re-scrolling the page back to the original position?

Here's most of the grid definition:

change: onChange,
sortable: {
mode: 'multiple'
},
groupable: true,
filterable: true,
navigatable: true,
resizable: true,
selectable: 'multiple row',

I've searched a bit, and found a few threads with something that sounds similar (http://www.telerik.com/forums/grid-jumps-or-scrolls-to-top-on-row-click), but the claim is that the issue was resolved with 2013.1.417

Can anyone shed some light on this? Many thanks

ClientTemplate causes error

I was having some issues with a grid where I was getting an error saying that Description is not field that can be called on a null value, or something along those lines. TimeType is of type TimeTypeViewModel.

public class TimeTypeViewModel

{

public override string ID { get; set; }

public override string Description { get; set; }

}

columns.Bound(p => p.TimeType).Hidden(true).ClientTemplate("#= (typeof TimeType != 'undefined') ? TimeType.Description : ''#");

but the following code doesn't cause me any issues

but code doesn't cause me any issues

columns.Bound(p => p.TimeType).Hidden(true).ClientTemplate("#= typeof TimeType == 'undefined' || TimeType == null ? '' : TimeType.Description #");

Why is this? It seems that all the values (i.e. 'TimeType.Description') are being evaluated in the expression before actually checking to see if they should be evaluated based on the inline if condition. Is this a bug? Is this me not understanding how templates work? Is my code somehow bad, or only works on certain types?

Configure Data Transport to include Header / ContentType

Using a Kendo Grid to do inline editing. It works absolutely great and love everything Kendo brings to the table. I'm working on doing some refactoring and trying to remove as much duplicate code from an application because ... well because it needs to happen. :-)

So I'm curious, is there a way to specify default values for transport. For example, below you can see a Read, Update, Destroy and in each case I have to set the content type, send auth tokens in the header, etc.

Thanks,

Richard

transport: {

// eslint-disable-next-line consistent-return

parameterMap: function (data, type) {

if (type !== "read" && data) {

return kendo.stringify(data);

}

},

read: {

url: "https://api.domain.com/Billings/",

dataType: "json",

beforeSend: function (xhr) {

xhr.setRequestHeader("TOKEN", "SomethingHere");

xhr.setRequestHeader("SECRET", "SomethingHere");

}

},

update: {

type: "PUT",

url: "https://api.domain.com/Billing",

dataType: "json",

contentType: "application/json;charset=utf-8",

beforeSend: function (xhr) {

xhr.setRequestHeader("TOKEN", "SomethingHere");

xhr.setRequestHeader("SECRET", "SomethingHere");

}

},

destroy: {

type: "DELETE",

url: "https://api.domain.com/Billing",

dataType: "json",

contentType: "application/json;charset=utf-8",

beforeSend: function (xhr) {

xhr.setRequestHeader("TOKEN", "SomethingHere");

xhr.setRequestHeader("SECRET", "SomethingHere");

}

},

ForeignKey column does not work under multi-column header

Hello,

I figured out that when I put a foreign key column under a multi-column header, it does not connect to the reference data source and shows raw foreign keys (numbers) instead.

Please see https://dojo.telerik.com/ipObEVAG for the example (made out of foreign key example).

Do I miss something or is it a bug?

Thanks.

Inline Edit Grid Showing Empty Rows

Hi Quite new to Telerik UI for Jquery. Trying to get an inline edit grid with ajax source. But for some reason all the rows are empty even though the ajax json result is not empty.

Have reference the demo Inline editing in https://demos.telerik.com/kendo-ui/grid/editing-inline but still unable to identify the issue. Here's my code below. Does any one know wat the issue is? or point me in the right direction? P.S can ignore the transport links... once I get read to work, then can move on to other links..

Thanks.

01.var crudServiceBaseUrl = "";

02. dataSource = new kendo.data.DataSource({

03. transport: {

04. read: {

05. url: "@Url.Action("KendoGrid_Read","Admin")",

06. dataType: "json"

07. },

08. update: {

09. url: crudServiceBaseUrl + "/Products/Update",

10. dataType: "jsonp"

11. },

12. destroy: {

13. url: crudServiceBaseUrl + "/Products/Destroy",

14. dataType: "jsonp"

15. },

16. create: {

17. url: crudServiceBaseUrl + "/Products/Create",

18. dataType: "jsonp"

19. },

20. parameterMap: function(options, operation) {

21. if (operation !== "read" && options.models) {

22. return {models: kendo.stringify(options.models)};

23. }

24. }

25. },

26. batch: true,

27. pageSize: 20,

28. schema: {

29. data: "data",

30. total: "total",

31. errors: "errors",

32. model: {

33. fields: {

34. id:"CompanyId",

35. CompanyId: { type:"number", editable: false, nullable: false },

36. CompanyName: { type: "string", editable: false },

37. CompanyGroupId: { type:"number", editable: false },

38. IsActive: { type: "boolean" },

39. Multiplier: { type: "number", validation: { min: 0, required: false } }

40. }

41. }

42. }

43. });

44.

45.

46. $("#grid").kendoGrid({

47. dataSource: dataSource,

48. pageable: true,

49. height: 550,

50. toolbar: ["create"],

51. columns: [

52. { field: "CompanyName", title: "Company Name" },

53. { field: "CompanyGroupId", title: "Unit Price" },

54. { field: "Multiplier", title: "Multiplier" },

55. { field: "IsActive", title: "Is Active", width: "120px" },

56. { command: ["edit", "destroy"], title: " " }

57. ],

58. editable: "inline"

59. });

How can I use "Disable Items for Selection" in my situation?

https://docs.telerik.com/kendo-ui/controls/editors/dropdownlist/how-to/selection/disable-items-for-selection

{field: 'operDay', title: '조업요일', width: 100, editor: _this.columnEditor.dayDropDownEditor}

dayDropDownEditor : function (container, options) {

$('<input id="' + options.field + '" data-bind="value:' + options.field + '"/>')

.appendTo(container)

.kendoDropDownList({

suggest: true,

dataSource: [

{id:'1', name:'월요일', operDay: '월요일', isDeleted: false },

{operDay: '화요일', isDeleted: false },

{operDay: '수요일', isDeleted: false },

{operDay: '목요일', isDeleted: false },

{operDay: '금요일', isDeleted: false },

{operDay: '토요일', isDeleted: false },

{operDay: '일요일', isDeleted: false }

],

dataTextField: 'operDay',

dataValueField: 'operDay',

valuePrimitive: true,

select: function(e){

if(e.dataItem.isDeleted){

e.preventDefault();

alert("why?");

}

},

template: kendo.template($("#template").html())

});

}

Hello, I need the feature in the link above. Some of the dropbox items I specified are deactivated and reactivated upon request. But I don't know how to apply that code to my code. Because there are some differences. I attach my code above.

<input id="dropdownlist" /> <button class="k-button"> Mark Oranges as deleted</button>

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

<span class="#: isDeleted ? 'k-state-disabled': ''#">

#: name #

</span>

</script>

This is the part I don't know, and it's also where the error occurs.

1. I think there is no ID that can be specified because it creates input dynamically. = <input id: dropdownlist> (There is option.field, but it is not recognized even if it is specified as #operDay.) 1-1. As a result, you cannot access the dataSource. 2. Where should I write the <script> <span> ... </ span> </ script> section? column? jsp? I tried to template it in a column, but I get an "isDeleted is not defined" error. I'm thinking that I don't recognize it. Please let me know how you can use that code ...
