Bar Code

The Bar Code control is used to add bar code to a report.

Note:
The barcode quality can degrade when the report is exported to formats other than PDF. To ensure reliable barcode recognition, print the report directly from an application using the native printing methods.

The Module and Auto-Module properties of a control must be used with care.

On the Properties window, the Bar Code control properties are divided into the following tabs:

Appearance

Alignment

Changes the alignment of the bar code in relation to the control boundaries.

Background Color

Specifies the background colour of controls. The functionality is also available on the Report Designer tab ().

Border Color, Border Dash Style, Border Width and Borders

Specifies border settings for controls.

Font

Specifies the font settings for controls. Some of the functionality is available on the Report Designer tab.

Foreground Color

Specifies the text colour for controls. The functionality is also available on the Report Designer tab ().

Formatting Rules

Displays the Formatting Rules Editor window, used to choose which rules are applied to a report during report generation, and to define the priority of the applied rules.

Location

Specifies the location of the control in report measurement units.

Padding

Specifies indent values used to render the contents of the controls.

Size

Specifies the size of the control in report measurement units.

Style Priority

Defines the priority of various styles (for example, background colour or border colour).

Styles

Defines odd and even styles for the controls, as well as assigning an existing style to the them (or a newly created one).

Behavior

Anchor Horizontally

Specifies the horizontal anchoring style of the control, so that after page rendering it stays attached to the left control, right control, or both. The property setting is useful for data-bound controls located between controls, which are able to resize depending on their contents.

Anchor Vertically

Specifies the vertical anchoring style of the control, so that after page rendering it stays attached to the top control, bottom control, or both. The property setting is useful for data-bound controls located between upper and lower controls, which are able to resize depending on their contents.

Auto-Module

If the check box is selected, the bar code image is stretched to fit the width of the control. If the check box is not selected, the behavior is determined by the Module property.

Keep Together

Specifies whether the contents of the control can be horizontally split across pages. In other words, if the control occupies more space than remains on the page, the property specifies whether the control is split between the current page and the next, or printed entirely on the next page. If the control does not fit on the next page either, the control is split, regardless of the property value.

Module

Specifies the width of the narrowest bar or space in the barcode, in report measurement units.

If the Module property is set too low, the barcode output may be unreadable by a barcode scanner.

If the Auto-Module property check box is not selected, the barcode image can be generated with a Module property larger than the control itself. In this case, the control displays a warning.

Increase the dimensions of the control to resolve the warning.

Orientation

Specifies the content orientation of the control. There are four available orientation options (Normal, Upside Down, Rotate to the Left and Rotate to the Right)

Process Duplicates

Determines the behaviour of the control when the data source contains consecutive repeating records. The records can be processed as is (when the property is set to Leave), suppressed except for the first entry (Suppress) and suppressed with a blank space printed instead of the repeated records (Suppress and Shrink).

Process Null Values

Determines whether to process Null (blank) values if they appear in the control data source. Null values can be processed as is (when the property is set to Leave), suppressed (Suppress) and suppressed with a blank space printed instead of the blank records (Suppress and Shrink).

Scripts

Contains events which can be handled with scripts.

Show Text

Deterines whether to display the numerical value, or only the bar code within the control.

Symbology

Defines the mapping between the bar code text and an image. The bar code control supports only the linear 1D symbologies listed.

Visible

Specifies whether the control is visible when using the print preview.

Data

(Data Bindings)

If the current report is bound to data, the property is used to bind control properties (Bookmark, Navigation URL, Tag and Text) to a data field obtained from the report data source, and to apply a format string.

Tag

Adds additional information to a control; for example, the Id, by which the control can then be accessed 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 from the Tag > Binding drop-down list, select the required data field.

Text

Defines a string to be encoded as a bar code. Whether or nor this value is displayed within the control is specified using the Show Text property.

When a bar code is selected, entered text is automatically added to the control

If the content does not conform to the rules of the specified symbology (determined by the Symbology property), the control displays a warning, or automatically correct the input string by padding it with zeroes or only accepting an acceptable number of characters for display.

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

Text Format String

Displays the Format String Editor window, which is used to manage and customise the format of the control using a predefined format style.

Miscellaneous

(Name)

Determines the name of the control, by which it can be accessed in the Report Explorer, Properties window or via scripts.

Bookmark and Parent Bookmark

These properties are used to create a hierarchical structure within a report called a document map.

If the current report has a data source, the Bookmark property can be bound to a data field, obtained from the data source. To do this, expand the Data > Data Bindings drop-down list and select the required data field.

Navigation URL and Navigation Target

Use the Navigation URL property to specify a URL for web browser navigation when the control is clicked. The web browser displays a page in a window or a frame as specified in the Navigation Target property.

Note: A URL must have an appropriate prefix for example, 'http://'). Cross-references can be created within the report by assigning the name of the target control to the Navigation URL property, and setting the Navigation Target property to ‘_self'.

If the current report has 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 > Data Bindings drop-down list and select the required data field.

Snap Line Margins

Specifies the margins for the control, which are maintained when the control is aligned using snap lines.

Favorites

Right-click on the Favorites tab and select Edit Favorite Property List to display the Favorite Properties Editor, which is used to customise the available properties on the Favorites tab.
