Harness and Section forms
Adding a Button control

Field

Description

Select to determine when the button appears.

• Select Always to have the field appear at the time this area of the user form (section or flow action) is first work item sent or refreshed. This condition is checked only once.
• Select Other Condition to make the visibility depend on a when condition rule, a Boolean expression evaluated only once, or a test evaluated repeatedly upon JavaScript events.

If you selected Other Condition in the Visibility field, complete this field.

• The When Name key part of a when condition rule. Click() to review or create the rule.
• Expression based on the comparison of a pair of constants, properties, or both, combined by Boolean operators, such as .Color="Red". You can combine the expression with a when condition rule or another expression using the && and || operators.

As a best practice, use the Condition Builder to edit this field. Click ( ) to open the tool. See Using the Condition Builder to configure dynamic UI actions.

An icon that is not visible is also disabled and cannot be clicked.

Displays only for free form layouts.

Select to force the label text to wrap if it is longer than the button width specified. If this check box is not selected, the text visible on the button may appear truncated at runtime.

Field

Description

Enter text or select a property or field value that contains brief text, which appears on the button or as a text link.

As a best practice, start the text with a verb. Consider the collection of controls that appear at runtime collectively; provide each control with a clear and distinctive label. For example, Cancel order.

To allow users to execute an action using a shortcut key combination, include an ampersand character (&) immediately before a letter in the caption text. At runtime, users can press the ALT key and the letter key together to execute the activity. For example, enter &History as a caption text to allow users to access work item history with ALT + h. At runtime, the label appears with the shortcut key underscored.

If you use shortcut keys in your application, be careful to choose distinct letters for each control; for example, you can't have ALT + c as the label for both the Contents button and Close button. (To include an ampersand in a label as text, follow the ampersand by a space character.)

Use SmartPrompt to select a field value rule if you plan to localize the text. Enter no more than 64 characters. A field value rule with pyButtonLabel as the second key part and this text as the final key part is needed for each locale. When practical, choose a caption already included in a language pack, to simplify later localization. See About the Localization wizard.

Specify a tooltip to display when the user hovers the mouse pointer over the button. You can press the down arrow to select a property value or type the text that you want to display as the tooltip.

As a best practice, start the sentence with a verb, either in the imperative ("Enter price of item here") or as an infinitive ("To cancel the order, click here").

Use SmartPrompt to select a field value rule if you plan to localize the text. See About the Localization wizard.

Select a pre-defined format (Standard, Simple, Strong), which is configured in the Skin rule. The default selection is Standard. Use the Skin rule to modify the settings for these formats.

Alternatively, select Other to reference a custom format created in the Skin rule. Press the down arrow in the field that displays to select the format that you want to use.

• None
• Simple image
  
• Property
• Icon Class

Insert an icon next to the label by clicking the magnifying glass icon (). This opens the Image Viewer. Select the binary file you wish to use.

If the button or link Format, for example, Standard, contains an image in the background, then that image overlays the image specified here. Button and link formats are defined in the Skin rule.

Appears when you enter an image in the Image field.

Select Left or Right to indicate where you want the image to appear in relation to the label.

Appears if you selected Property as the Image source.

Press the down arrow to select the property that you want to use as the source of the image/icon. The property can be an internal binary file (Rule-File-Binary) or an external URL.

Select Yes if you want to apply a when condition that tests whether the user can use the control. If selected, the following options appear:

Select the Privilege Name key part of a privilege rule that controls the availability of this control at runtime. During rule resolution at runtime, the system uses the Applies To key part of the current rule as the first key part.

If there is a privilege and a when rule (see Disabled field), both rules must evaluate to true for the button to be available to the user.

Appears when you enter a privilege. Select Hide or Disable (the button) if the user fails the privilege rule.

Select this check box to display fields that enable you to specify custom styles.

As a best practice, define custom styles in the skin. See Skin form — Components tab — General — Custom styles.

Appears only when you select the Display advanced presentation options check box.

As a best practice, do not select this check box; instead define custom styles in the skin. See Skin form — Components tab — General — Custom styles.

• Read-write style — Type the name of the custom style, for example, custom_stylename, that you want to apply to this cell when the user form or flow action form appears in read-write mode.
• Read-only style — Type the name of the custom style, for example, custom_stylename, that you want to apply to this cell when the user form or flow action form appears in read-only mode.
• Inline style — Type CSS code to define an inline style. As a best practice, define custom styles in the skin. See Skin form — Components tab — General — Custom styles.
