Definition and Usage

Examples

HTMLAnchor
ASPX Source:
<script runat="server">
Sub Page_Load
link1.HRef="http://www.w3schools.com"
link1.Target="_blank"
link1.Title="W3Schools"

link2.HRef="http://www.microsoft.com"
link2.Target="_blank"
link2.Title="Microsoft"
End Sub
</script>

<html>
<body>

<form runat="server">
<a id="link1" runat="server">Visit W3Schools!</a>
<br />
<a id="link2" runat="server">Visit Microsoft!</a>
</form>

</body>
</html>
Output Result:

Visit W3Schools!
Visit Microsoft!


In this example we declare two HtmlAnchor controls in an .aspx file (remember to embed the control inside an HtmlForm control). Then we modify the URL, target, and title of the HtmlAnchor controls in an event handler (an event handler is a subroutine that executes code for a given event). The Page_Load event is one of many events that ASP .NET understands.
