HtmlButton Control

Definition and Usage

The HtmlButton control is used to control a <button> element. In HTML, the <button> element is used to create a push button.

Properties

Property	Description
id	A unique id for the control
OnServerClick	The name of the function to be executed when the button is clicked
runat	Specifies that the control is a server control. Must be set to "server"

Example 1

In the following example we declare two HtmlButton controls in an .aspx file (remember to embed the control inside an HtmlForm control). Next, write an event handler that specifies what to happen when a button is clicked:

<script runat="server">
  Sub b1_OnClick(Source As Object, e As EventArgs)
    s1.InnerHtml="You clicked Button1"
  End Sub
  Sub b2_OnClick(Source As Object, e As EventArgs)
    s1.InnerHtml="You clicked Button2"
  End Sub
</script>

<html>
<body>
<form runat="server">
<button id="b1"
  OnServerClick="b1_OnClick"
  style="background-color:lightgreen;
  height=30;width:100"
  runat="server">
  Click me!
</button>
<button id=b2 
  OnServerClick="b2_OnClick" 
  style="background-color:yellow;
  height=30;width:100"
  runat="server">
  Click me too!
</button>
<span id="s1" runat="server"/>
</form>
</body>
</html>
