TLabel class

TLabel displays a piece of text on a Web page. Use Text property to set the text to be displayed. TLabel will render the contents enclosed within its component tag if Text is empty. To use TLabel as a form label, associate it with a control by setting the ForControl property. The associated control must be locatable within the label's naming container. If the associated control is not visible, the label will not be rendered, either.

Note, Text will NOT be encoded for rendering. Make sure it does not contain dangerous characters that you want to avoid.

Since: 3.0
