错误1“ItsWeb.Relation.LeftList”并不包含“UserBox”的定义

解决方案 »

  1.   

    把 UserBox  先从页面里删除  在 把 拖一个在页面里  你试一下
      

  2.   

    <asp:Label   id= "lblCaption "   runat= "server "> Label </asp:Label> 
    <asp:TextBox   ID= "UserBox "   runat= "server "   Width= "90px "   OnTextChanged= "UserBox_TextChanged "> </asp:TextBox>
    <asp:Button   ID= "BtnUser "   runat= "server "   Text= "搜   索 "   OnClick= "BtnUser_Click "   />
    id="XXX",runat="server"
    去掉里面的空格
