asp.net 2.0 中ICallbackEventHandler的使用(无刷新页面)

function callToServer()

var context = "";

<% = blientScript %>

Result : <INPUT id="txtResult" />

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

public partial class _Default : System .Web.UI .Page , System.Web.UI.ICallbackEventHandler

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected String blientScript

{

get

{

return this.ClientScript.GetCallbackEventReference(this, "param", "handleResultFromServer", "context");

}

public string RaiseCallbackEvent(string eventArgument)

{

return "客户端在[" + DateTime.Now.ToString() + "]传送来 [" + eventArgument + "].";

}

原来作者那个无法通过调试....应当这样...

return this.ClientScript.GetCallbackEventReference(this, "param", "handleResultFromServer", "context"); //应当这样在 (asp.net beta2 中)

//参考
