Hello,
I am trying to create a custom MVVM widget. I noticed that when my widget is bound and the "visible" binding is declared -- this error logs in the console:
typeError: cannot read property '0' of undefined.
I have created a dojo from an example provided in your tutorial on how to build a custom widget and am able to reproduce:
https://dojo.telerik.com/ayaQEsaV
Please advise.

Hi Guys,
.kendoMenu({dataSource: menuItems}); menuItems is JSON from the controller.
In my C# code, I have the property as Text (capital 'T'), but KendoUI expects a small 't'. I don't want to have properties in my C# starting with small letters. How do I tell Kendo that it should look for 'Text' rather than 'text'?
Thanks,
Andrei

Hi,
I am having a requirement for conditional cell colouring in Kendo UI grid and user should be able to extract the same coloured cells in excel using Kendo Export to Excel feature.
Please refer the attached screenshot in which I need to colour based on following conditions
1) Colour the entire Order ID column with Gray background
2) Colour Green and yellow background for the selected country and state in Ship Country and Ship city respectively
3) Mark Red colour for those columns where Freight is less than 25
So, I am looking for a way through achieve this conditional colouring in export to excel as well, i.e. by clicking on export to excel user can download the excel with all these cells coloured.
Can you please assist me in achieving this.

I need to be able to restrict the allowed files types in the upload widget. I see there's some old threads on this (here and here), but any links to examples are dead now.
Ideally I would be able to pull a list of allowed file types from our DB to be used with the uploader, but if it has to be a static list, that would work as well.

I started to write my first app with Kendo UI. Most of the work will be done on the Kendo Grid by filtering, sorting and manipulating values.
The grid itself seems to be pretty powerful and suits my needs quite well. However, it looks like I am not able to fulfill all my filtering needs using the regular built-in filtering functions.
For instance: I need to be able to filter all the items from a column having some special characters in them. Special characters are input by the user via k-textbox.
I already wrote a JS function that returns true/false depending on whether the given string contains any of the special character present in the k-textbox.
How could I bind this function as a filter operator for column filtering? I would like to have it on the client side so that I don’t need to send data back and forth all the time. I tried searching for solutions from the forum and the web in general, but I am still a bit lost.
It would be neat if I could use it as a string filter operator like the built-in filters, something like this:
Any ideas and help are welcome. Thank you!

I created a .css file from http://themebuilder.telerik.com/aspnet-mvc based on Bootstrap 4. When I downloaded it, I noticed that the 'WebComponentsIcons' WOFF is now embedded as base64. GREAT!
However, often when I refresh my browser (F5), the sort, filter, paging icons do not render properly and give me ugly ASCII chars (please see attached).

I was checking out https://demos.telerik.com/kendo-ui/treeview/filter-treeview-in-dialog for a demo on how to client-side filter a treeview component. The demo works like a charm butI noticed that keyboard navigation is broken when the treeview is filtered (it works fine when not filtered). Is there a work around of fix for this problem?
Thanks,
Ron

Hello,
I face a problem with treeview and larger tree structure. When I select some item and the modal window appears, I cannot see the selected item, it is necessary to scroll down, if selected item is out of visible area.
The second problem I face is witjh automatic scroll, when moving around tree using keyboard, automatic scroll does not work.
Thank you for your kind help.
