Harness and Section forms - Adding a Text Area control |
A text area is an area in which the user types or pastes one or multiple lines of text, without formatting the text.
If formatting is required, use a Rich Text Editor control instead. If the text content is only a few words, use a Text Input control instead of the Text Area or Rich Text Editor controls.
A cell in a layout can present the value of a property as display-only or as an input field using the TextArea control, pxTextArea. You can configure a text area control, specifying the width, height, and maximum number of characters that users can enter into the text area. You can also display placeholder text and/or tooltips at runtime and configure actions based on events.
If you are building a Mobile application, see Supported user interface features for mobile applications.
The UI Gallery landing page contains a working sample. To view and interact with the sample, select > User Interface > UI Gallery. In the Components area, select Text Area.
Field |
Description |
Property |
Press the down arrow to select a property reference that identifies a single text value. Alternatively, you can drag a property name from the lists of properties visible in the Application Explorer. Typically, this works for () to review the property (if the reference is to an existing property in the Applies To class of this rule or a parent of that class). If the property is not found, the New dialog box for the property form appears. You can reference properties on any page identified on the Pages & Classes tab, using the normal notation pagename.propertyname for pages other than the page corresponding to the Applies To class of the rule. If this field is in a cell of a section that includes parameter declarations on the Parameters tab, you can enter the notation param.NAME here, to use a parameter value for the field, where NAME identifies a string parameter. Make sure that the NAME parameter is declared on the Parameters tab, and that your application provides a non-blank value for the parameter value in all possible situations where the section appears. See Sections — Completing the Parameter tab. For a harness, the property generally must be on the primary page of the rule — the page corresponding to the Applies To key part of the rule. However, a section within the harness may have a different Applies To class, and that section can include properties from its own class. If this field is always displayed as read-only, you can enter a linked property reference here, of the form .AAAA.BBBB, where AAAA is the linked property and BBBB is any property reference in the object identified by the value of AAAA as a key. For example, if the property AAAA has a value corresponding to a key of a Data-Admin-Operator-ID instance, then .AAAA.pyUserName presents that Operator ID's full name. This allows values from that object to appear (read-only) in the run-time display, though your processing does not explicitly load the object onto the clipboard. |
Default value |
Optional. Enter a constant value for the property value, a property reference, or an expression, to be used only when the user form or flow action form appears in read-write mode rather than read-only mode. Choose a default value that speeds data entry. When the system renders a harness or section in read-only mode (for example because the read-write mode requires a privilege that the current user does not hold), the default value does not appear, because data entry is not permitted. |
Visibility |
To control the visibility of the label, select one of the following:
If this section is to become part of navigation in a composite portal, you can make the header visible only when a specific space is the current space. Enter an expression here similar to the following: pyCurrentSpace=="ASpaceName" Then select the Run visibility condition on client checkbox. |
Disable |
Select to disable the text input:
|
Wrap Text | Select if the label is to be presented as multiple lines when the text is longer than the cell width. If this checkbox box is not selected, the label may appear truncated at runtime. |
Required | This box appears only for fields in cells on flow actions and sections. Select to require that (when the form appears at runtime in read-write mode) users cannot successfully submit the form if the field is blank.
Selecting Required marks the label for this field with an orange asterisk () when the flow action form appears in read-write mode. (The asterisk also appears if the Label control's Value For field is not blank and the Label control's Required box is checked.) For sections, checking this box enables client-side format validation when this section is part of a harness form that has the Enable Client Side Validation box selected on the HTML tab. At runtime, users who leave this field blank and submit the form are notified immediately that the field is required; the form is not transmitted to the server. |

Edit Options | Select an edit mode for this control. The edit mode of the control, specified here, takes precedence over section and harness settings.

Read-only when | Appears only when you select Read Only in the Edit Options field. Enter or select one of the following:
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. |
||||||||||||||
Specify width |
Select Auto if you want the layout to determine the width of the control area. This is the default. If you want to specify the width, select Custom and set the width in columns, pixels, or percent. |
||||||||||||||
Specify height |
Select Auto if you want the layout to determine the height of the control area. This is the default. If you want to specify the height, you can select Size to Content, which means setting the minimum number of pixels or rows to display, or Custom to set the height in pixels or percent. |
||||||||||||||
Min/Max characters |
Optional. Enter a value that determines the minimum and maximum number of characters that can be entered in the text input. You can designate either value as unlimited by leaving it blank. |
||||||||||||||
Tooltip |
If you want to display a tooltip when the user hovers the mouse pointer over the text input, press the down arrow to select the property that you want to display as a tooltip or type a text string within quotations, for example, "Select to open an item". |
||||||||||||||
Placeholder
|
Select None if you do not want to display placeholder text. Select Other if you want to display a hint or instructional text in the field. The text disappears when the user enters a value. If the user does not enter a value, the placeholder text reappears when the field loses focus. |
||||||||||||||
Style |
Specifies the format of the text input. You can style text input controls and create additional formats in the skin rule. To select a custom format, press the down arrow and select Other. |
||||||||||||||
Advanced Options |
The best practice is to define custom styles in the skin.
|

Auto Prepend |
Appears if Type is Select a property or constant that you want to add either before the displayed property value. For example, when the user name appears, the system can automatically prepend the user's title. |
||||||||||||||
Auto Append |
Appears if Type is Select a property or constant that you want to add after the displayed property value. For example, when the user name appears, the system can automatically append the full mail extension to the name. |
||||||||||||||
Show Value As |
Appears if the Type is Select to label either outcome using Text or an Image. |
||||||||||||||
True Image
False Image |
Appears if the Type is Select an image to label either outcome. Used with a boolean type. |
||||||||||||||
True Text
False Text |
Appears if the Type is Enter a text string to label either outcome. Used with a boolean type. If the Localize? checkbox is selected on the section's HTML tab, a SmartPrompt Appears in the Constant field in the Parameters dialog. Select a field value rule if you plan to localize the text. If this text is to be localized, enter no more than 64 characters. A field value rule with pyCaption as the second key part and this text as the final key part is needed for each locale. |
