Not getting tooltip on line chart series

[Rahul Khinvasara]

When I create a rad line chart series programatically and add items to the series programatically I am unable to see the active region tooltip when I run the radchart. The code I am using is as follows:
foreach (ChartSeries series in RadChart1.Series)
            {
                foreach (ChartSeriesItem item in series.Items)
                {

                    if (item.YValue < chartwarning)
                    {
                        item.Appearance.FillStyle.MainColor = Color.Red;
                        item.Appearance.FillStyle.SecondColor = Color.Red;
                        item.Appearance.Border.Color = Color.Red;
                        item.ActiveRegion.Tooltip = "warning below 0.8500";
                    }
                    else if (item.YValue >= chartwarning && item.YValue < chartcaution)
                    {
                        item.Appearance.FillStyle.MainColor = Color.Yellow;
                        item.Appearance.FillStyle.SecondColor = Color.Yellow;
                        item.Appearance.Border.Color = Color.Yellow;
                        item.ActiveRegion.Tooltip = "between caution and warning";
                    }
                    else if (item.YValue >= chartcaution && item.YValue < chartgoal)
                    {
                        item.Appearance.FillStyle.MainColor = (System.Drawing.Color)colConvert.ConvertFromString("#1010A6");
                        item.Appearance.FillStyle.SecondColor = (System.Drawing.Color)colConvert.ConvertFromString("#1010A6");
                        item.Appearance.Border.Color = (System.Drawing.Color)colConvert.ConvertFromString("#1010A6");
                        item.ActiveRegion.Tooltip = "above caution";
                    }
                    else if (item.YValue >= chartgoal)
                    {
                        item.Appearance.FillStyle.MainColor = Color.Green;
                        item.Appearance.FillStyle.SecondColor = Color.Green;
                        item.Appearance.Border.Color = Color.Green;
                        item.ActiveRegion.Tooltip = "Goal";
                    }
                    item.Label.TextBlock.Appearance.Dimensions.Margins.Top = 5;
                    item.Label.Appearance.RotationAngle = -90;
                    item.Label.TextBlock.Appearance.TextProperties.Color = Color.Black;
                }
            }
        }

What shall I do so that I can obtain tooltip for the entire line series as well as for individual chart series items i.e individual points on the line series?

Hi Rahul,

To achieve this you should set Visible = true for the PointMark. Here is an example:

series.Appearance.PointMark.Visible = True
series.Appearance.PointMark.FillStyle.MainColor=Red
series.ActiveRegionToolTip = "MySeriesToolTip"

after this you can set tooltip for the entire item:

item.ActiveRegion.ToolTip = "MyItemToolTip"
