回滚__doPostBack
关于回滚__doPostBack('dopostbackbtn','')出错的问题？有谁知道吗？详情请进......
我有一服务器按钮ID号为：dopostbackbtn,我在单击事情中写了许多代码。
System.Text.StringBuilder sb=new System.Text.StringBuilder();
sb.Append("<a href=\"javascript:__doPostBack('dopostbackbtn','')\">首页</A>");
ageInfo.Text=sb.ToString();
我想点击首页就去执行dopostbackbtn按钮中的代码怎么不行呢？

sb.Append("<A href='#' onclick=\"document.getElementById('Button1').click()\">"+min.ToString()+"</A> ");
我点击上面的 min超链接现在可以回滚到后台事件了，多谢 回复人： LoveCherry(论成败，人生豪迈；大不了，重头再来！^_^) ,我现在回滚的时候能候在后台Button1事件中得到点击的超链接min文本字符值如何得到？
谢谢 。

answer is no, you are on the wrong track, use a linkbutton instead
<asp:LinkButton id="lb" runat="server" OnClick="YourEventHandler" />
..
lb.Text = min;

思归老大:我其实就是想实现
http://bbs.openlab.net.cn/ShowForum.aspx?ForumID=31 的翻页功能:
总页数 41 第 1 页 [共有 807 条记录] 1 2 3 4 5 » ... 末页 »
点击第几页时我希望到后台去执行代码.有办法吗?

I already answered you, use LinkButton
<asp:PlaceHolder id="ph" runat="server" />
for (int i=0; i < .. ; i++)
{
LinkButton lb = new LinkButton();
lb.Click += new EventHandler(YourMethodHere);
lb.ID = i.ToString();
lb.Text = (i+1).ToString();
ph.Controls.Add(lb);
ph.Controls.Add( new LiteralControl(" "));
}
void YourMethodHere(object sender, EventArgs e)
{
LinkButton lb = (LinkButton)sender;
//...
}

思归老大:我按你的试了,当我点击第几页时事情是回滚,可并没有执行代码,反而一点击那个ph就从页面上消失了,怎么回事?
while(min<=max)
{
LinkButton lb = new LinkButton();
lb.Click += new EventHandler(gopagex);
lb.ID = min.ToString();
lb.Text = min.ToString();
ph.Controls.Add(lb);
ph.Controls.Add( new LiteralControl(" "));
//sb.Append("<asp:LinkButton id='lb"+min.ToString()+"' runat='server' OnClick='Button1_Click'>"+min.ToString()+"</asp:LinkButton> ");
//sb.Append("<A href='#' onclick=\"document.getElementById('Button1').click()\">"+min.ToString()+"</A> ");
min=min+1;
}
private void gopagex(object sender, EventArgs e)
{
LinkButton lb = (LinkButton)sender;
ViewState["current_page"]=Convert.ToInt32(lb.Text.Trim());//当前页Convert.ToInt32(Request["__EVENTARGUMENT" ].ToString());（用记户所点击的超链接）
string commstring=SplitPage.StratDetachPage((int)ViewState["pagesize"],(int)ViewState["current_page"],(int)ViewState["count"],"menu4","keyid,img","writetime",false,ViewState["where"].ToString());
DataTable tb=DbProvider.Instance().GetRecordsBySql(commstring);
ImagesData.DataSource=tb;
ImagesData.DataBind();
SetPages();
}

you need to re-create the buttons upon postback

是不是点击linkbutton时要重新建立这些linkbuttion?
可是点击它时并没有执行lb.Click += new EventHandler(gopagex);
中的 gopagex过程啊?

doPostBack 不是回滚，只是提交服务端而已。实际就是submit
