根据用户条件,组合成查询表达式,高手帮我看一下
搜索按钮的代码:(将参数传如到ArticlesList.aspx中去)  
Private   Sub   button1_Click(ByVal   sender   As   Object,   ByVal   e   As   System.EventArgs)   Handles   button1.Click  
Dim   str   As   String  
str   =   "akinds= "   &   dropdownlist1.SelectedValue  
str   +=   "infor=   "   &   textbox1.Text  
str   +=   "seekid=   "   &   dropdownlist2.SelectedValue  
Response.Redirect( "articleslist.aspx? "   &   str)  
End   Sub  

ArticlesList.aspx中的部分代码:  
Private   Sub   Page_Load(ByVal   sender   As   System.Object,   ByVal   e   As   System.EventArgs)   Handles   MyBase.Load  
'在此处放置初始化页的用户代码  
If   Not   Page.IsPostBack   Then  
viewstate( "pagenow ")   =   0  
Dim   akinds   As   String   =   Request.Params( "akind ")  
Dim   seekid   As   String   =   Request.Params( "seekid ")  
Dim   infor   As   String   =   Request.Params( "infor ")  
Dim   moreid   As   String   =   Request.Params( "moreid ")  
If   moreid   =   " "   Then  
If   akinds   =   " "   Or   seekid   =   " "   Or   infor   =   " "   Then  
Response.Redirect( "default.aspx ")  
Else  
If   akinds   =   "-1 "   Then  
mysql   =   "   where   "   +   seekid   +   "   like   '% "   +   infor   +   "% ' "  
Else  
mysql   =   "   where   akinds= "   +   akinds   +   "   and   "   +   seekid   +   "   like   '% "   +   infor   +   "% '   "  
End   If  
End   If  
Else  
mysql   =   "   where   akinds= "   +   Request.Params( "moreid ")  
End   If  
getdatainfor()  
getdata()  
End   If  
End   Sub  

我的问题出在哪里啊?为什么点击按钮没有反应的  

高手帮忙看看啦  

谢谢!


------解决方案--------------------
是不是事件丢失了
------解决方案--------------------
Response.Redirect( "articleslist.aspx?id＝ "＋str) c#的写法
------解决方案--------------------
设置段点,看下mysql的值:
(在getdatainfor()行 上面设置)
