Import data from multiple excel files into different tabs in one kendo spreadsheet workbook

Hi, is it possible to do this? It is easy to import the data from one excel workbook (using the fromFile method), but then I would like to allow the user to load in data from additional excel workbooks and have the data display on new tabs of the kendo workbook. At the moment, each additional import overwrites the previous one.

Thanks for any help :)

Add ng-model code to AngularJS demo

Just a quick request to modify one of the examples in the angular js demo of the drop down list to include basic ng-model code.

https://demos.telerik.com/kendo-ui/dropdownlist/angular

I know it's well documented in the API but I think it would be a minimum requirement for a demo.

Cheers

I can never get anything to work in Telerik or Kendo. It starting to get dumb and tiring!!

Ok so!

I am following a tutorial and the tutorial show how you can take an existing visual studio program and add Telerik to it.

Under the telerik menu option in visual studio I select Telerik UI for asp.net mvc then I select upgrade wizard.

Well silly me thought that the wizard after all its wizarding would add what I needed to my visual studio mvc project.

well well... I guess not. Gullible me thought something that we paid alot of money for would do what it claimed it would do.

NOPE!

Can some one tell when what is going wrong here...

I am adding a date time picker to a page. It does not work.

I did notice that the location that the wizard added was not in my actual file directory

where it is looking... so do I have to manually copy those files there??

Here is the source code:

The Razor index.cshtml page

@{
ViewBag.Title = "My Kiosk";
}

@(Html.Kendo().DatePicker().Name("Date").Value(DateTime.Today))

The Layout page for the mvc application there the link to the kendo stuff is:

<!DOCTYPE html>
<html>
<head>

<meta http-equiv="X-UA-Compatible" content="IE=11,chrome=1">

<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<title>@ViewBag.Title - XXXXX</title>

@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")

<link href="@Url.Content("~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/kendo/2020.2.617/jszip.min.js")"></script>
<script src="@Url.Content("~/Scripts/bootstrap.min.js")"></script>
</head>
<body>

Here are the errors I get on the the web browser

GET http://localhost:50296/Scripts/kendo/2020.2.617/jszip.min.js net::ERR_ABORTED 404 (Not Found)

bootstrap.min.js:6 Uncaught Error: Bootstrap's JavaScript requires jQuery at bootstrap.min.js:6

AJAX Error: error POST - Status Code 0

Hi Everyone,

The company I work for use KendoUI through JQuery and MVC.

We are doing Ajax calls via KendoGrid using Razor Pages. We have been getting a few status code 0 Ajax errors and are unsure how to proceed.
We log all of our errors into Raygun but once logged these Ajax errors do not have a stacktrace other than the message.

I.E: "AJAX ERROR: error POST /File/Controller/Method/Parameters".

Theses errors do not always occur to every customer, and often happen sporadically.

We have ruled out the possibility of firewall/timeouts due to other calls becoming success seconds before and after these calls.
What else could be the reason for these status code 0 ajax calls?
What is the most efficient way log an error stacktrace through these KendoGrid Ajax calls?
Or better how can we avoid status code 0?

Thanks in advance.

avoid multiple dataBound/dataBind on pushUpdate with array

Hi, its me again with (gantt) dataSource and changes... and this is pretty urgent :(

I have a following situation, I need to change 5-10 resources/assignments on gantt task and I do it using pushUpdate method by sending an array of items to be updated. (dataSource.pushUpdate(arrayOfItemsForChange))

However this slows widget down because even if one pushUpdate is called, dataBound and dataBind events are triggered for each of them, and these events have some custom code as well (some proposed by support people here as well).
I did some measurements and for 7 items it takes approx 6 seconds to handle this on gantt, during which gantt "freezes" not allowing any action on the timeline.

Is there any way I can have widget (gantt) trigger dataBound and dataBind only once, at the and end then render everything it needs?

Thank you very much.

Best regards,

Vedad

Stockchart categoryAxis Issue

Hi,

I'd like to use stockchart to display my data across thirty years scale with proximately two data per week. However, setting baseUnit to "days" will cause categoryAxis's label overlapping each other. How can I display the data "daily" in chart and make categoryAxis's label display act like setting baseUnit to "monthly" or "yearly"?

Thanks,

Bob
