I found the following section regarding exporting large datasets from the Kendo Grid:

http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/excel-export#use-server-side-processing

We currently have this exact need, but I am unable to find any code giving an example of how to tie the grid data to the TDP library. The closest I can find relating to exporting with this library is http://docs.telerik.com/devtools/document-processing/libraries/radspreadstreamprocessing/export but the code samples are not closely related to my situation. Can you provide or point me to some code samples that show how to process a large data set from a Kendo grid?

 

Thank you.

Is there a solution (or workaround) to the following problem: 

Tooltips are only displayed for active ("enabled") listbox items. 

I have two linked listboxes (ListBoxA and ListBoxB). ListBoxA shows valid and invalid entries. Invalid entries are disabled in ListBoxA so that they cannot be added to ListBoxB. I want to display tooltips for all entries in ListBoxA so that the user can see why an entry may be is disabled.

I've modified the first example at https://docs.telerik.com/kendo-ui/framework/datasource/crud by using a model that is strictly typed with kendo.data.Model.define instead of using the flat JSON object array. If I click on the edit button in a row in the grid and change the value of "Units in Stock" and then click on the cancel button, the change will NOT be discarded. The error "kendo.all.min.js: 27 Uncaught TypeError: n.wrap is not a function" is displayed in the browser's developer console.

 

What do I have to change so that the example with kendo.dataModel.define works correctly?

HI, I want to have a kendo drop down list with multiselect and filtration options into it. I don't want to use kendo multiselect widget. 

I need to have only kendo dropdownlist with multiselect and filter option so that i can select the options from the drop down and display into my custom div container.

 

Kindly suggest any option for this. please refer the screen shot.

I am using KendoUI components to write a mobile friendly website. I've come across my first issue with the KendoUI controls. I have an Input DOM element as below:

and the javascript behind this is as follows:

after the kendo control has been created, both the new input tag created by kendo and the old ones have both had their "type" properties set to "text" instead of "number". This has now completely removed the benefits on a phone where a context specific (i.e a number pad) is displayed when a "number" type input is selected.
Is there any way I can change the type property back to "number", or is there anything i'm missing?.
I can change the type of the original input object by just doing the below after the kendo control is made

but this doesn't help the actual control now visible to the user. I've also tried the wrapper and element properties on the numericTextBox object as below

but this did not seem to change the property of the visible control, the "element" only changed the value of the original now hidden Input element.
Any ideas where i've gone wrong, or how I can achieve this?

I am getting below error on our search screen.
This happens only when searched from specific field ( Group), if we search from any other field then we do not get this error.

Hi,

I'm trying to define my custom (annual) view on scheduler in angularJS.

My definition is:

 

Hi Telerik community,

I hope you all are doing well.

One question, did some has a situation to add custom fields into a From Component, or for example a ListBox component?

Thank you & regards,

Dear Kendo team,

Our organization security vulnerability team has reported us on Jquery version 1.12.3 which is shipped with Kendo(2017.2.504) package and advised us to update to Jquery 3.5.1, we have read here that Kendo 2020.2.513 version supports Jquery 3.5.1. We would like hear from you if you would recommend this shift, if yes what implications do you foresee in terms of Compatibility, Existing control initialization and events based on your support experience and any best practice guide for migration

Kendo 2017.2.504 to 2020.2.513

Jquery 1.12.3 to Jquery 3.5.1

 

Thanks, Ashok

Hi,

 I am using the {0:C} format for a number column in the grid, the positive values are showing correctly but when there are negative values they are shown in brackets for e.g. ($203.00) instead of -$203.00. I want to show the negative symbol instead of bracket also how to customize the currency symbol, I want to show text instead of symbol.

 Please suggest to fix the issue.

 Thanks in advance.
