Hi,

I use the event "ChartRegionMouseDown" to know the column index, but I don't know how to highlight this column.

Best regards,

Martin

Hi Martin,

Thanks for your interest in Syncfusion Products.

If your intention is to highlight a specific column when the mouse is over that column then it can be done by setting the AutoHighlight property as shown in the code snippet below,

this.chartControl1.AutoHighlight = true;

or if you want highlight the Column with the color of your wish then it can done as shown in the code snippet below,

this.chartControl1.AutoHighlight = true;
this.chartControl1.Series[0].Style.HighlightInterior = new BrushInfo(GradientStyle.ForwardDiagonal,Color.Blue,Color.White);

Also kindly take a look at the ChartAutoHighLightSample ( Syncfusion\Essential Studio\4.4.0.51\Windows\Chart.Windows\Samples\User Interaction\ChartAutoHighLightSample ) which ships with our Essential Chart ProductPackage.

In this sample, the point(column) of series over which the mouse is placed gets highlighted.

Let me know if you have any queries.

Thanks & Regards,
Ramya.

Hi,

I need to highlight a column on a MouseClick event and the column needs to stay highlighted until the next MouseClick.

Best regards,

Martin

Hi Martin,

Thank you for the update.

I have created a sample with your requirement. In this sample, I am getting current style of the series point by using GetOfflineStyle() method. Please have a look at this sample and let me know if this helps you.
