Examples
HTMLImage
In this example, we declare an HtmlImage control in a .aspx file (remember to nest the control inside an HtmlForm control). Then we modify the src, alt, and border attributes of the HtmlImage control in an event handler (an event handler is a subroutine that executes code for a given event). The Page_Load event is one of the many events that ASP.NET understands.
HTMLImage 2
In this example, we declare an HtmlImage control and an HTMLSelect control in a .aspx file (remember to nest the controls inside an HtmlForm control). Then we modify the src attribute of the HtmlImage control based on the user's selection. The selected value in the HTMLSelect control determines which image is displayed.
