12.1.2.1.1.23. Rich Textbox

A rich textbox control is a form element that allows users to input and format text with a wide range of styling options, such as bold and italic text, bullet points, and hyperlinks.

*Unlike a multi-line textbox, which only allows plain text input, rich textbox controls provide a more flexible and expressive way to create and edit text-based content.

When a rich textbox control is selected in the design environment, its associated properties are displayed in the Control Properties panel.

*To access the Control Behavior category, users must first create the form behavior.

1. Binding: In this category, users can link a control to its corresponding attribute and define its binding properties.

2. Name: In this category, users can access basic properties required for the control’s identification and proper referencing in the code.

4. Appearance: In this category, users can customize the visual appearance of the control.
   • Height: This is a numeric updown field that allows users to set the height of the control.
     • By default, the height is set to 250. To adjust this size, users can enter numbers into the field either manually or by clicking the increment/decrement arrows.
   • Tooltip: This field allows users to input a tooltip for the control.
     • In the web application, the tooltip is represented by the tooltip icon ( ) next to the control.
