1.在父页里的选择点击按钮事件写
//弹出模态窗口，选择人员
string strTemp,strUrl;

strTemp="<script language=\"javascript\">";
strTemp+="";

strTemp+="var newwin = window.showModalDialog(";

strUrl="\'SelectPersons.aspx?sTxt="+Server.UrlEncode(this.txtPersonName.Text)+"&sVal="+this.txtPersonNo.Text+"'";

strTemp+=strUrl+",window,\"dialogWidth:500px;DialogHeight=350px;status:no;help:no;scroll:no\");";
strTemp+="</script>";

Page.RegisterStartupScript("",strTemp);
2.在SelectPersons.aspx里写

这个问题，其实很简单

出现此问题的原因的于
在模式对话框中提交给服务器时，会新开一个窗口

解决方案

在页面加上下列语句即可
<head>
<base target=_self>
</head>

如此一来，模式对话框就能向普通页面一样提交了
接下来的事，就不用我说啦

对话框用用户控件实现，并弹出窗口

this.Label.Text = "<a onclick=window.open('"+index.aspx?ContactNo="+strAutoID.ToString()+"','popuppage','width=400,height=380,top=130,left=200,scrollbars,resizable') style='CURSOR: hand'>"+e.Item.Cells[2].Text.ToString()+"</a>";
