Hi all,

  am using telerik reporting chart.

please tell me how to do mouse hover option in pie, line charts etc.

previously i used radchart. so i can able to do mouse hover option.

protected void chartPie_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
        {
           
                    e.SeriesItem.Name = ((DataRowView)e.DataItem)["lab_name"].ToString();
                    e.SeriesItem.ActiveRegion.Tooltip = ((DataRowView)e.DataItem)["lab_name"].ToString();

Hello sabarishbabu,

The short answer is that you can't. As explained in the Known limitations of Telerik Reporting, interactivity features are not yet supported.

Has this issue been addressed with the latest release of Reporting?  Is there any other workaround?
thanks

Hi Michael,

As you can see from the referenced Known Limitations topic in my previous post, tooltips are not yet supported in general. This is specifically hard task for the chart item as it renders as image and you do not have "reference" to its separate elements.

Kind regards,
Steve

This would be a very important feature in the Line Chart.

Hello Markus,

Such feature is considered for R1 2017 release, expected in the middle of January - Telerik Reporting Roadmap.

For the time being, you can apply custom actions on categories and series of the Graph item - Graph Item Actions. An example of handling custom actions in a viewer is avilable in How to add interactivity to a report using action event handlers in WinForms report viewer.

Stef
