                                  • Hello support,

                                    the chartHitInfo.seriespoint is always null while hovering over a side by side range bar. See attached sample.

                                    This worked correct under the previous DevExpress version (v2012 vol 1.4)

                                    Best regards,

                                    Goos van Beek

                                I suggest that you handle the ObjectHotTracked event:

                                	
                                [C#]
                                private void ChartControlPlanning_ObjectHotTracked(object sender, HotTrackEventArgs e)
        {
            if (e.AdditionalObject is SeriesPoint)
                if (((SeriesPoint)e.AdditionalObject) != null)
                    Text = Text + '!';

        }

                                Attached is a modified sample project that demonstrates how to accomplish this.

                                  Hi Valdermar,

                                  Thanks for your suggestion. It works fine that way.
                                  I was wondering if something has changed; the code I used was working well before.

                                  Regards,
                                  Goos.

                                  Thank you for the additional clarification. I will discuss this behavior with our developers.

                                • Valdemar (DevExpress Support) 07.30.2012

                                  I believe you are referring to a known issue: we changed the default ChartControl behavior in the latest version (2012.1.5) to improve the overall drawing performance. At present, the ChartControl.RuntimeHitTesting property is set to False by default (BC1699). To resolve the issue, set the RuntimeHitTesting property to True.

                                • Goos van Beek 07.30.2012

                                  Thanks. I wasn't aware of the BC1699 change and never checked the RunTimeHitTesting property.
                                  Using the ObjectHotTracked event seems the best to me now.

                                  Regards,
                                  Goos.
