Hi Alberto,

Currently this is not possible and the only tooltips that can be attached to the RadHtmlChart items are its own built-in tooltips. We are planning to extend their functionality to include a form of templates, yet this concept is still in the oven.


Kind regards,

Hi Telerik admins,

I would like to attach a complex RadToolTipManager object to the items on the htmlchart.

My scenario is as follows:

for each item in the series (I use line series) I would like show an extended tooltip the contains pie chart based on the selected item.

Of course the data for the pies comes from the server side.

Still I cannot see that you support such a functionality...

I tried to workaround this using OnClientSeriesHovered event but there is no "on client series mouse leave" and I don't want to use onmouseleave of the chart element.

Do you have any other suggestions?

Thank you very much.

Regards,

Ronen.

Hi Ronen,

RadHtmlChart renders SVG, canvas or VML, so one cannot simply get the position for the tooltip from outside code, hence the fact that RadToolTips are difficult to use with RadHtmlChart.

The only other approach I can offer is using the seriesClick event to show a popup like RadWindow with the needed data (e.g., you can pass a querystring parameter with the needed data to know what to load in the content page).
