I have attached a context menu to the chart. Very often the context menu does not appear after right-clicking the chart. CPU usage is zero. It happens in release and debug versions. Does anybody have any idea? Regards Andi

Hi Andi, I am afraid that I am not able to reproduce the issue. Are you using any specific conditions for diaplaying the ContextMenu? If so could you please send me the code implementation part of it so that it will be easier to look into the cause of the problem? Thanks and Regards, Geetha.

Hi Geetha, it''s a tooltip issue. As soon as tooltips are enabled, I have the problem. You can reproduce the behaviour with the following source code (extention of F40628.zip). What I need are tooltips for the data points. But as far as I know I just can enable tooltips for the whole chart. Is there a possibility to enable tooltips just for a series?

Hi Andi, You can display customized tooltip by setting the PointsToolTipFormat of ChartSeries appropriately. Please refer the attached sample to get an elaborate idea about how to display customized tooltips. SetToolTip.zip Please let me know if this helps you. Thanks and Regards, Geetha.

Hi Geetha, thank you for the response. As soon as you set this.chartControl1.ShowToolTips = true; a context menu is not available anymore, when the tooltip is showing up. Can I show tooltips for points without setting ShowToolTips = true? That is because I want to show tooltips with information of the points, but I don''t use tooltips for the chart area. Regards Andi

Hi Andi, I am able to reproduce the issue now (context menu does not appear). But I am afraid it is not possible to show tooltips without setting ShowToolTips = true. I will log a QA report on this and will let you know as soon as the bug is fixed. Thanks for your continued support for Syncfusion products. Regards, Geetha
