_attachBubbleHandlers

I am designing a hierarchy of pages and components and I am trying to figure out what _attachBubbleHandlers is used for considering it basically does:

that._data.bind(ERROR, e => {

that.trigger(ERROR, e);

});

where that._data is an ObservableArray which never triggers the error event.

See https://github.com/telerik/kendo-ui-core/blob/master/src/kendo.data.js#L4856

Please clarify.

Example Tooltip Basic usage with resizable Image

Hello,

how can I modify the example Tooltip / Basic usage for a resizable image? On my mobile phone only the half of the image is shown. But when I make the image resizable, then the absolute positions if the tooltips don't match.
Is an example available?

Prevent read from DataSource on bind?

Is there a way to prevent the datasource from doing a read when I use the setDatasource Method? I have a case where I'm using the same datasource for multiple sheets, and each bind is causing a read.

VM Function used for mvvm source is called 4 times!

I have recreated this problem in the kendo dojo... I do not understand why a function within my viewmodel is called 4 times when it is clearly only bound once. I see this in production and in the dojo, so it is clearly an issue with either they way I am configuring/binding/using mvvm or something within kendo.

See the dojo:

http://dojo.telerik.com/uhENaZAh/11

Thanks for any help or clarity,

What Version provided that Feature?

Good Morning to all of you!

So is there a resources that correlates when a feature first become available in a version of the Kendo UI control? For example, I want to use the selectedKeyNames method of the grid. Sadly we are not up-to-date on our versions, and while it might sound easy to upgrade to the latest, it is not. We have a much older app that is paired to an older version of jQuery and would require a lot of testing on combinations based on JavaScript Prerequisites.

What I would love to see is some sort of documentation on the API docs saying when a feature was first released.

I look forward to any responses.

Peace,
Keith

Hello,

I have a realtime chart with refresh every second. After the refresh the crosshair tooltip and zoom selection (with left mouse key) are gone. See http://dojo.telerik.com/uTEseYiz

I want to keep the croshair tooltip visible and the chart should be zoomable. Now the user must complete the zoom action before the next refresh occurs.
