DxSankeyHoverStyleSettings Class

Contains hover style settings for the DxSankey component.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public class DxSankeyHoverStyleSettings :
    DxComplexSettingsComponent<DxSankeyHoverStyleSettings, SankeyHoverStyleSettingsModel>,
    IModelProvider<BorderSettingsModel>,
    IModelProvider<HatchSettingsModel>

Remarks

Use the DxSankeyHoverStyleSettings object to configure hover style settings for the following components:

DxSankeyNodeSettings

Contains settings for DxSankey nodes.

DxSankeyLinkSettings

Contains settings for DxSankey links.

When a user hovers a mouse over a DxSankey node or link, the corresponding element changes its appearance. You can set the Sankey component’s ChangeStyleOnHover property to false to disable this effect.

Add a DxSankeyHoverStyleSettings object to the DxSankeyNodeSettings or DxSankeyLinkSettings markup to access and configure hover style settings for nodes or links.

<DxSankey Data="@Data"
          SourceFieldName="Source"
          TargetFieldName="Target"
          WeightFieldName="Weight">
    <DxSankeyNodeSettings Width="8" Spacing="30">
        <DxSankeyHoverStyleSettings Color="#5f368d" Opacity="0.6" />
    </DxSankeyNodeSettings>
    <DxSankeyLinkSettings ColorMode="SankeyLinkColorMode.Gradient">
        <DxSankeyHoverStyleSettings Color="#888" Opacity="0.6" />
    </DxSankeyLinkSettings>
</DxSankey>
