I'm trying to change the grouping dynamically with a button (on/off or other resources).

But when I change the group via code, the scheduler isn't updated.

How can I make it dynamically?

Thanks

How to have 'read more' and 'read less' functionality if there is large content in a cell in Kendo grid for Angular 6 ?

So inside cell on the third line of text we could have a 'read more'  and on clicking on 'read more' the row expands vertically and shows the rest of the content ending with 'read less'. 

How to wrap the content inside a cell so that full content is visible and it does not overflow and there should not be ellipsis (...) if the content is large.

Hi i have to export my scheduler into pdf but when i export the style content in the file is not the same with the component

Hi,

We are using the Kendo grid with Angular 6 in our project. We are using grid features like Inline editing, Lock, Sorting(server-side), Filtering(server-side), Paging(server-side), Keyboard Navigation etc.
Grid responds very slow when the number of columns is more. When we have 50 to 60 columns. Single Click navigation, Keyboard navigation, Row editing etc. are taking 3 to 4 seconds delay. 

I have tested after reducing the number of columns to10 to 15. then it works fine.

Could you please help us in resolving the same. 

I presume the component is handling the increment of the input value when the mouse wheel is turned. 

Is there a way to stop the incrementation or a way to override the handler for this event?
