SectionOptions Interface

Provides options for a new section in the Dashboard Item Menu and Data Item Menu.

Declaration

export interface SectionOptions

Remarks

Handle the OptionsPanelExtensionOptions.onCustomizeSections or BindingPanelExtensionOptions.onCustomizeDataItemContainerSections events and call the e.addSection method. Pass a SectionOptions object as the addSection method’s parameter. Use the SectionOptions.items property to specify editors for a new section.

The following code adds a new section to the Options menu:

1. Create a custom property (an axisMaxValueConstantProperty object). Users can change its value in an editor displayed in the newly added section.
2. Handle the onCustomizeSections event and use the CustomizeSectionsEventArgs.addSection method to add the new section.

var Model = DevExpress.Dashboard.Model;

const axisMaxValueConstantProperty = {
    ownerType: Model.ChartItem,
    propertyName: "AxisMaxValueConstant",
    defaultValue: 100,
    valueType: 'number'
};
Model.registerCustomProperty(axisMaxValueConstantProperty);
// ...
function onCustomizeSections(args) {
    args.addSection({
        title: "Primary Axis Max Value (Custom)",
        items: [
            {
                dataField: axisMaxValueConstantProperty.propertyName,
                editorType: "dxNumberBox",
                label: {
                    text: "Value",
                }
            }
        ]
    })
}
