Example
- HTMLInputHidden
- In this example, we declare an HtmlInputHidden control, an HtmlInputText control, an HtmlInputButton control, and an HtmlGeneric control in the .aspx file. When the submit button is triggered, the submit subroutine will be executed. This submit subroutine will set the value of the hidden field to the value of the input field and display the value of the hidden field in the p element.
