A tooltip is a small pop-up rectangle that displays information about a series point when a user hovers the cursor over it and indicates the point’s value by default. It is possible to display other information and customize the appearance of a tooltip or its text.


You can access tooltip options using the chart’s BootstrapChartBase.SettingsToolTip property. To enable tooltips, set the BootstrapUIWidgetTooltipSettings.Enabled property to true.

<dx:BootstrapPieChart ID="BootstrapPieChart1" runat="server" ... >
    <SettingsToolTip Enabled="true"></SettingsToolTip>
