Sparkline

The Sparkline control displays a compact chart that is commonly used to reflect the flow of data for every row in a report.

In the Property Grid, the Sparkline control's properties are divided into the following groups.

Expanded Appearance

  • Background Color

    Specifies the background color for the control. This option is also available in the Formatting Toolbar ().

  • Borders, Border Color, Border Width, and Border Dash Style

    Specify border settings for the control.

  • Formatting Rules

    Invokes the Formatting Rules Editor, which allows you to choose which rules should be applied to a control during report generation, and define the precedence of the applied rules. To learn more on this, refer to Conditionally Change a Control's Appearance.

  • Padding

    Specifies indent values that are used to render the contents of a Label.

  • Style Priority

    Specifies the priority of various style elements (such as background color, border color, etc.). For more information on style inheritance, refer to Understanding Style Concepts.

  • Styles

    Assigns an existing (or newly created) style to the control, and also specifies odd and even styles.. For more information on style inheritance, refer to Understanding Style Concepts.

  • View

    Specifies the type of a chart displayed by a Sparkline control. The following table lists the available Sparkline view types.

    Area

Expanded Behavior

  • Anchor Vertically

    Specifies the vertical anchor style of the control, so that after a page is rendered it stays attached to the top control, bottom control, or both.

  • Scripts

    This property contains events that you can handle with the required scripts. For more information on scripting, refer to Handle Events via Scripts.

  • Visible

    Specifies whether the control should be visible in a print preview.

Expanded Data

  • (Data Bindings)

    If the current report is bound to data, this property allows you to bind some of the control's properties (Bookmark, Navigation URL, Tag and Text) to a data field obtained from the report's data source, and to apply a format string to it. For more information on this, refer to Displaying Values from a Database (Binding Report Elements to Data).

  • Data Adapter

    Determines the data adapter that will populate the Sparkline's data source, which is assigned via the Data Source property. It is automatically set to the appropriate value when the Data Member property is defined.

  • Data Member

    Determines the data source member that supplies data to a Sparkline.

    Note

    Usually, it is not necessary to specify the Data Member property when binding a Sparkline to data. This property should only be set directly if the dataset contains more than one table.

  • Data Source

    Determines a Sparkline's data source.

  • Tag

    This property allows you to add some additional information to the control; for example its id, by which it can then be accessible via scripts.

    If the current report has a data source, the Tag property can be bound to a data field obtained from the data source. To do this, expand the (Data Bindings) property, and in the Tag.Binding drop-down selector, select the required data field.

  • Value Member

    Specifies the data member field that provides point values for a Sparkline.

Expanded Design

Expanded Layout

Expanded Navigation

  • Bookmark and Parent Bookmark

    These properties are intended for the creation of a hierarchical structure within a report called a document map. For more information, refer to the Add Bookmarks topic.

    If the current report is bound to a data source, the Bookmark property can be bound to a data field obtained from the data source. To do this, expand the (Data Bindings) property, and in the Bookmark.Binding drop-down selector, select the required data field.

  • Navigation URL and Navigation Target

    Use the Navigation URL property to specify a URL for web browser navigation when a user clicks a Label. The web browser displays a page in a window or a frame as specified by the Navigation Target property. Note that a URL should have an appropriate prefix (e.g., "http://"). You can create cross-references within the report by assigning the name of the target control to the Navigation URL property, and setting the Navigation Target property to "_self". For more information, refer to Create Hyperlinks.

    If the current report is bound to a data source, the Navigation URL property can be bound to a data field obtained from the data source. To do this, expand the (Data Bindings) property, and in the Navigation URL.Binding drop-down selector, select the required data field.
