Type:

Function

Function parameters:
e:

Object

Information about the event.

Object structure:
Name Type Description
component

Bullet

The UI component's instance.

element

HTMLElement | jQuery

The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.

model any

The model data. Available only if you use Knockout.

Default Value: null
Cannot be used in themes.

onTooltipShown

A function that is executed when a tooltip appears.

Type:

Function

Function parameters:
e:

Object

Information about the event.

Object structure:
Name Type Description
component

Bullet

The UI component's instance.

element

HTMLElement | jQuery

The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.

model any

The model data. Available only if you use Knockout.

Default Value: null
Cannot be used in themes.

pathModified

Notifies the UI component that it is embedded into an HTML page that uses a tag modifying the path.

Type:

Boolean

Default Value: false
Cannot be used in themes.

If you place the UI component on a page that uses a tag modifying the path (<base>, <iframe>, etc.), some of the UI component elements may get mixed up or disappear. To solve this problem, set the pathModified property to true.

See Also

rtlEnabled

Switches the UI component to a right-to-left representation.

Type:

Boolean

Default Value: false
Cannot be used in themes.

When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

JavaScript
DevExpress.config({
    rtlEnabled: true
});
NOTE
In a right-to-left representation, SVG elements have the direction attribute with the rtl value. This might cause problems when rendering left-to-right texts. Use this property if you have only right-to-left texts.

showTarget

Specifies whether or not to show the target line.

Type:

Boolean

Default Value: true

showZeroLevel

Specifies whether or not to show the line indicating zero on the invisible scale.

Type:

Boolean

Default Value: true

size

Specifies the UI component's size in pixels.

Type:

Object

Default Value: undefined

By default, the UI component occupies the entire area of the container. If you need to set a particular size for the UI component, different from the container's size, assign a height and width in pixels to height and width properties of the size object.

Using the size object, you can hide the UI component. For this purpose, simply assign 0 to both the height and width of the UI component.

NOTE
The size configuration object reserves space for the main UI component elements, while displaying a tooltip may require extra space. To reserve the area around the UI component for the tooltip, you can apply a margin to the UI component's container.

startScaleValue

Specifies a start value for the invisible scale.

Type:

Number

Default Value: 0
Cannot be used in themes.

The main, target and zero values of the Bullet UI component are contained within a range. This range is represented by an invisible scale. To specify the boundary values of this scale, set the startScaleValue and endScaleValue properties.

Specify the same start and end scale values for several bullets when you display them in a column so that they can be comparable visually.

target

Specifies the value indicated by the target line.

Type:

Number

Default Value: 0
Cannot be used in themes.

targetColor

Specifies a color for both the target and zero level lines.

Type:

String

Default Value: '#666666'

This property supports the following colors:

To specify a color for the bullet bar, use the color property.

targetWidth

Specifies the width of the target line.

Type:

Number

Default Value: 4

theme

Sets the name of the theme the UI component uses.

Type:

String

Default Value: 'generic.light'
Accepted Values: 'generic.dark' | 'generic.light' | 'generic.contrast' | 'generic.carmine' | 'generic.darkmoon' | 'generic.darkviolet' | 'generic.greenmist' | 'generic.softblue' | 'material.blue.light' | 'material.lime.light' | 'material.orange.light' | 'material.purple.light' | 'material.teal.light'

A theme is a UI component configuration that gives the UI component a distinctive appearance. Use can use one of the predefined themes or create a custom one. Changing the property values in the UI component's configuration object overrides the theme's corresponding values.

Use the VizTheme enum to specify this property when the UI component is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: GenericLight, GenericDark, GenericContrast, GenericCarmine, GenericDarkMoon, GenericSoftBlue, GenericDarkViolet, GenericGreenMist, MaterialBlueLight, MaterialLimeLight, MaterialOrangeLight, MaterialPurpleLight, MaterialTealLight.

tooltip

Configures the tooltip.

Type:

Object

A tooltip is a miniature rectangle displaying UI component data. The tooltip appears when the end-user hovers the cursor over the UI component. You can enable/disable the tooltip, change its appearance and format its text using fields of the tooltip configuration object.

NOTE
The tooltip is displayed outside the UI component's container. If you plan to use the tooltip, make sure there is enough space around your UI component to display it. For example, you can apply a margin to the UI component's container to reserve the area around the UI component for the tooltip.

value

Specifies the primary value indicated by the bullet bar.

Type:

Number

Default Value: 0
Cannot be used in themes.
