Pega Platform includes a set of standard auto-generated controls. As a best practice, use these controls to save development time and ensure consistency. By default, this tab is displayed when you open an auto-generated control or open a New rule.
Auto-generated controls provide these benefits:
- Eliminate hand-coding, which simplifies design and maintenance.
- Let you to customize a control in a section or harness without having to make multiple copies and reconfigurations.
- Preserve custom settings when you upgrade your system.
- Ensure browser independence and compatibility.
Customizing a control in a section
Auto-generated controls are optimized for most interfaces. If necessary, edit the settings within the section, flow action, or harness in which you are working.
- Open the section or harness that contains the rule.
- Select the cell that holds the rule and click the View properties icon to open its Cell Properties window.
- In the panel, click the Open icon next to the control name.
The control Parameters tab opens, which lists the available settings. Note, that you cannot edit the Control Modes or UI Element settings.
- Modify the settings and save the section.
The system generates the XML representing your edits and stores it in the section.
To reuse a modified control, save a copy of this control to 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.
If you want to revert to the control's configuration, clear the customized instance and re-add the rule.
For more information, see Controls in offline mode.

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
If you use shortcut keys in your application, be careful to choose distinct
letters for each control; for example, you can't have
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.

As a best practice, start the sentence with 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. Enter no more than 64 characters. A field value rule with pyActionPrompt as the second key part and this text as the final key part is needed for each locale.

|Privilege||Optional. Available when the Control Mode is Action . |
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.
|When Not Met||Available when you enter a privilege. Select |

the Binary File rule form. See Creating binary file rules. |
The numbers in the drop-down reflect the number of columns in the sprite. Select the number you wish to use for this control's action. The value in the Tooltip field applies to this position.
For information about icon positions, hover the mouse pointer on the help icon next to this field.
