JavaScript/jQuery Bullet Options

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

To specify a color for the target and zero level lines, use the targetColor option.

You can configure this option in an ASP.NET MVC Control as follows:

@(Html.DevExtreme().WidgetName()
    .ElementAttr("class", "class-name")
    // ===== or =====
    .ElementAttr(new {
        @id = "elementId",
        @class = "class-name"
    })
    // ===== or =====
    .ElementAttr(new Dictionary<string, object>() {
        { "id", "elementId" },
        { "class", "class-name" }
    })

)

@(Html.DevExtreme().WidgetName() _
    .ElementAttr("class", "class-name")
    ' ===== or =====
    .ElementAttr(New With {
        .id = "elementId",
        .class = "class-name"
    })
    ' ===== or =====
    .ElementAttr(New Dictionary(Of String, Object) From {
        { "id", "elementId" },
        { "class", "class-name" }
    })
)

The primary, target and zero values of the Bullet widget are held within a range. This range is represented by an invisible scale. To specify the boundary values of this scale, set the startScaleValue and endScaleValue options.

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

When an error or warning appears, the widget notifies you by passing a message to the browser console. This message contains the ID of the incident, a brief description, and a link to the Errors and Warnings section where further information about this incident can be found. However, you can handle errors and warnings in the way that you require. To do this, implement a callback function performing the required actions and assign it to the onIncidentOccurred option. Within this function, you can use information about the incident that occurred. This information can be accessed from the target field of the object passed to the callback function as a parameter. This information includes the following.

• id
  Contains the ID of the incident. The full list of IDs can be found in the Errors and Warnings section.
• type
  Contains the type of the incident. This field equals "error" for errors or "warning" for warnings.
• args
  Contains the argument of the incident's message. The content of this field varies greatly, depending on the incident. For example, it may contain the name of the data source field that was not specified correctly, or the name of the option that was not set properly.
• text
  Contains the text passed to the browser console. This text includes the content of the args field, if there are any.
• widget
  Contains the name of the widget that produced the error or warning.
• version
  Contains the currently used version of the DevExtreme library.

You cannot access widget elements in this handler because it is executed before they are ready. Use the onDrawn handler instead.

The sparkline's tooltip becomes invisible when a user moves the mouse cursor outside of the widget.

When a tooltip is made hidden, you can perform specific actions by handling the tooltipHidden event. To do this, implement a handling function and assign it to this option. When implementing a handling function, use the object passed to it as its parameter. This object will provide you with the widget instance and its container.

The sparkline's tooltip appears when a user hovers the mouse cursor over it.

When a tooltip appears, you can perform specific actions by handling the tooltipShown event. To do this, implement a handling function and assign it to this option. When implementing this function, use the object passed to it as its parameter. This object will provide you with the widget instance and its container.

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

When this option is set to true, the widget 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.

DevExpress.config({
    rtlEnabled: true
});

By default, the widget occupies the entire area of the container. If you need to set a particular size for the widget, 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 widget. For this purpose, simply assign 0 to both the height and width of the widget.

The main, target and zero values of the Bullet widget 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 options.

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.

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

When using the widget as an ASP.NET MVC Control, specify this option using the VizTheme enum. This enum accepts the following values: GenericLight, GenericDark, GenericContrast, GenericCarmine, GenericDarkMoon, GenericSoftBlue, GenericDarkViolet, GenericGreenMist, Android5Light, IOS7Default, Win10Black and Win10White.

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