Click Event

[Jer]

Will you be adding a click event like the RadCharts have in the near future?

[Marin Bratanov]

Hello Jer,

 We are planning to add a click event for the series, yet at the current state of affairs I cannot provide a firm estimate on when it will be available. If possible, it will be included in the service pack, otherwise I hope the rest of the high-priority tasks will allow us to make it for the Q3 2012 release. You can stay tuned and monitor the release notes and demos to see when this feature will be available.


Kind regards,

Hi, I'm trying to achieve the same functionality. Is there a work around to create the same behaviour as the onclick event? Thanks

Hi guys,

 I am glad to inform you that we have added OnClientSeriesHovered and OnClientSeriesClicked events for the RadHtmlChart and they will be available in the upcoming SP release. The events expose all needed relevant information and you can easily use them for fine tuning, e.g if you need to perform a server action, you could make an ajax request. Along with the new events, we have also added new demos /will be also available when the SP release is out/ showing them in action - a drill down chart scenario and client events console one.


I hope that the provided information is helpful, let us know in case new questions arise.

All the best,

Hi Svetlina,

Is it possible for you to tell me the date this service pack is expected to be released as we are heavily anticipating this functionality.

Hi Rob,

 The SP is scheduled for next week, if everything goes by plan it should be available till its end.

hello telerik team,

I am using two client side events of RadHtmlChart
1) OnClientSeriesClicked
2) OnClientSeriesHovered

I am creating a pie chart using radHtmlchart.I want to set the SeriesItem.Exploded = true on OnClientSeriesHovered and to set it false when the series item is unhovered. Please help how i achieve this, or how i can set the exploded = true when OnClientSeriesHovered client side event is called.

Also, can you suggest any kind of animation effect i can include in my Pie chart.This will really be helpful for me.

Thanks,
Aakansha

Hello Aakansha,

I have just answered your support ticket with the same question and I am pasting my reply below in case someone else has a similar question.

Currently it is not possible to change series properties on the client. We are considering this option, yet I cannot provide any estimate on it, because the planning for the Q3 2012 release has already been completed and the tasks have been set.

The animation that a PieChart can have is the same as any other - when it is being rendered there is a short animation effect. The Transitions property can disable it when you set it to false.

Is there a way to change series properties on the client yet?

[Marin Bratanov]

Hi Andy,

It is possible to toggle seriesItems properties, you can see it in the updated API of the control:
http://www.telerik.com/help/aspnet-ajax/htmlchart-client-side-api.html
http://www.telerik.com/help/aspnet-ajax/htmlchart-client-side-onclientseriesclicked.html
http://demos.telerik.com/aspnet-ajax/htmlchart/examples/clientsidedatabinding/defaultcs.aspx
In these resources you will find an example of setting an entirely new datasource, of modifying an existing item and you will also see a full list with the data available in the event.
The following blog post will show you the new features that were added in Q1 2013: http://blogs.telerik.com/aspnet-ajax/posts/13-03-04/what-s-new-in-radhtmlchart-in-q1-2013.
