Web Server Controls->ASP.NET LinkButton Control

Definition and Usage

The LinkButton control is used to create a hyperlink button.

Note: This control looks like a HyperLink control but has the same functionality as the Button control!

Examples

LinkButton
ASPX Source:

<script  runat="server">
Sub lblClick(sender As Object, e As EventArgs)
   Label1.Text="You clicked the LinkButton control"
End Sub
</script>

<html>
<body>

<form runat="server">
<asp:LinkButton Text="Click me!" OnClick="lblClick" runat="server" />
<p><asp:Label id="Label1" runat="server" /></p>
</form>

</body>
</html>

Output Result:
Click me!  
  IF you click the linkbutton "Click me!',it will show:
Click me!

You clicked the LinkButton control


In this example we declare one LinkButton control and one Label control in an .aspx file. When the user clicks on the link, the lbClick subroutine is executed. The subroutine sends the text "You clicked the LinkButton control" to the Label control.
