Example
- HTMLTextarea
- In this example, we declare an HtmlTextarea control, an HtmlInputButton control, and an HtmlGeneric control in the .aspx file. When the submit button is triggered, the submit subroutine is executed. This submit subroutine sends the message "You wrote: " and the text entered by the user in the text box to the p element.
