DxChartAnnotationBase<T>.TooltipEnabled Property

Specifies whether the annotation tooltip is enabled.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(true)]
[Parameter]
public bool TooltipEnabled { get; set; }

Property Value

Type	Default	Description
Boolean	true	true to enable the annotation tooltip; otherwise, false.

Remarks

The Chart component displays tooltips when a user hovers a mouse pointer over chart annotations. Use the TooltipText property to specify tooltip text content. To disable tooltip functionality for an annotation, set the TooltipEnabled property to false.

Important

Annotation tooltips are incompatible with chart tooltips. If you enable both tooltips, only chart tooltips appear. To display annotation tooltips only, set the DxChartTooltip.Enabled property to false or remove the entire DxChartTooltip object from chart markup.
