Text Reader control

This control creates a text box that you can expand or collapse to show or hide sections of text that are larger than a specified number of characters. The extra text is hidden until the user clicks Show More or a similar link that you can specify.

Data binding

Set or modify the data binding for the control in the General properties tab. The Text Reader control can be bound to a String variable.

Configuration properties

Set or modify configuration properties for the control, such as appearance and behavior properties, in the Configuration properties tab.

Screen size: A configuration property that has the Screen Sizes icon beside the property name can have different values for each screen size. If you do not set a value, the screen size inherits the value of the next larger screen size as its default value. If you are using the Process Designer desktop editor, you are setting the value for the large screen size. The other screen sizes inherit this value.

Theme definitions: Theme definitions specify the colors and styles for a control and determine the appearance of the control. You can preview the look and feel of controls in the theme editor. See Themes.

The Text Reader control has the following types of event handlers:

On load: Activated when the page loads. For example:

if (${DeviceSensor}.getDeviceInfo().isIPhone) {me.setExpanded(false);} else {me.setExpanded(true);}

On click: Activated when the control is clicked. For example:
```
me.toggleExpanded()
```
On expand: Activated when the user expands the text. For example:
```
${TextReader2}.setExpanded(false)
```
