I use filterable multi-checkbox menu component as it's guided here https://www.telerik.com/kendo-angular-ui/components/grid/filtering/reusable-filter/#toc-multi-checkbox-menu-filtering but it does not work for empty values. If I select an empty value in filter menu, the Filtering button is not enabled, even if I select more values, the result will still not include empty values.

Hi,

I'm using tooltip module (2.1.0) under Material theme. It works perfectly except the font is too small to see (guess it's 10px). So I'm trying to use tooltipClass with a customized style, following example in https://www.telerik.com/kendo-angular-ui/components/tooltip/how-to/customize-styling/. But strangely it doesn't work, the tooltip still showing the original styles. Other properties of the TooltipDirective works, such as showOn, tooltipHeight, etc. Not sure where I did wrong.

I also have Angular Material controls on the page, was suspecting there's confliction of the styles but removing those controls doesn't help. What might cause tooltipClass not work?

Attached is the screenshot of the tooltip even after applying tooltipClass.

If there's other approach can increase the font size rather than a customized style I'd love it.

Thanks,

Randy

Is is possible to overlay two chart types in the same chart? I would like to create line and scatter chart combined - similar to the chart seen attached to this post.

I am using kendo angular Toolbar. In Jquery version they have event for overflow button clicked. But i didnt find for Angular. Any way we can achieve it.

Angular: https://www.telerik.com/kendo-angular-ui/components/toolbar/responsive-toolbar/
jQuery: https://docs.telerik.com/kendo-ui/api/javascript/ui/toolbar/events/overflowopen

I need to preventDefault because my webpage is getting refreshed on click of overflow button.

How can this be fixed? 

I have attached a pic of the issue.

Thanks.

In my app I dynamically create angular material tabs, which each contain a kendo grid. 

The problem is when a tab is closed, by clicking on the X in its header, the memory isn't garbage collected. I am implementing ngOnDestroy in my dynamic components and observable subscriptions are cleaned up here. I am also calling ComponentRef.destroy() to ensure the component is destroyed and can confirm ngOnDestroy() is getting called in the dynamically created copmonents. However the memory from the destroyed component isn't being released.

Is there any special cleanup required by Kendo Grid to release memory? Please advise.

Thank you.

I have a kendo grid with many columns, and defining filters in each column header is not the best user experience as it requires lots of scrolling and button clicks to open a dialog per column to define filter parameters. 

I have been asked to build a popup dialog which would load the column definitions and then generate a list of the columns and filter operator / filter value widgets so that a user could just open the popup, find the relevant column and then specify the filter operator and values.

Is there any plan to introduce such a feature in the grid soon? The ergonomics of filtering for multiple columns would be much improved with such a widget i think.

If I must roll my own implementation, is there any way I can hook in to the kendo code to build my filter list in a dialog, then apply it to the grid once it closes? How would I go about doing that?

Thanks

I have a screen using a Kendo Panel Bar to get the accordion effect.

Within 2 of the panels there is a component with a link in it that is used to open a Kendo Window to display extra data for the panel. First of all, the window actually belongs to the panel bar not the browser. When I collapse the panel, the window goes away. It does re-appear when expanding the panel though so I thought that was not a problem. However, since adding the component to the last panel bar, even when I click on the component's button from the first panel, the window does not show until I expand the last panel telling me that somehow it thinks it belongs to the wrong panel. Any assistance would be appreciated. I can try to get an example if needed.
