| 代码说明： 只要文本框的内容发生变化并且包含该文本框的表单被提交回服务器，该事件就被触发。
下面的程序使用TextChanged事件报告表单内的内容是否发生了变化.
<Script Runat="Server">
Sub Page_Load
lblMessage.Text = ""
End Sub
Sub txtSomeText_TextChanged( s As Object, e As EventArgs )
lblMessage.Text = "You changed the value!"
End Sub
</Script>
<html>
<head><title>TextBoxChanged.aspx</title></head>
<body>
<form Runat="Server">
<asp:TextBox
ID="txtSomeText"
Text="Apple"
OnTextChanged="txtSomeText_TextChanged"
Runat="Server"/>
<asp:Button
Text="Submit!"
Runat="Server"/>
<p>
<asp:Label
id="lblMessage"
Runat="Server" />
</form>
</body>
</html> |
