Control form
|
|
By default, this tab appears when you open an auto-generated control or open a New rule.
The Pega 7 Platform includes a set of standard auto-generated controls. See Standard auto-generated controls. As a best practice, use these controls in new development. Auto-generated controls provide these benefits:
Auto-generated controls and their settings are optimized for most interfaces. If necessary, edit the settings within the section, flow action, or harness in which you are working.
To customize an auto-generated control:
If you wish to modify an auto-generated control and reuse it in a number of sections, make a copy into your RuleSet and change the Stream Name key part. Keep the original Control Modes and UI Element settings. As a best practice, do use an auto-generated rule to build an entirely new control.
When you clear the Auto-Generated? check box on the HTML tab, the Parameters tab appears.
Caution: Any customization you make to the control in the section is maintained even if the control later changes. Parameters that are not customized apply to all of the instances. For example, if the Expand Options setting in the rule is Collapsed With Icon
and you customize the control's Parameter dialog setting to Expanded With Icon
, updating the rule setting to No Scrollbar
does not change the custom parameter. If you had not customized the Expand Options setting, your rule update is reflected in the control's Parameter dialog.
If you want to revert to the control's configuration, clear the customized instance and re-add the rule.
For custom mobile applications working offline, see Supported controls when working offline.
These settings determine the read-only and edit-mode presentation and behavior of the control.
Use this area to specify the control or category of property type used with the control.

Configuring labels 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

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.
