基于数据库信息在基于会话登录的基础上填充gridview

Question

我在基于会话的登录登录基础上填充gridview时遇到了问题。我正在使用母版页。目前我得到一个“必须声明标量变量”。我的想法是在脚本区域的某处找回它。任何帮助是极大的赞赏！！！！

现在的问题是代码应该为非主页面检索基于他们的uname（数据库中的列）或UID（主键和理想方式）的人的具体信息 母版页代码至少相关的东西）

protected void btnlogin2_Click(object sender, EventArgs e) 
{ 
    if (btnlogin2.Text == "Login") 
    { 

     string strCmd = "Select * From Person Where uname=@uname and upass=@upass"; 
     SqlConnection objConn = new SqlConnection(strConn); 
     SqlCommand objCmd = new SqlCommand(strCmd, objConn); 
     objCmd.Parameters.AddWithValue("@uname", txtusername.Text); 
     objCmd.Parameters.AddWithValue("@upass", txtpassword.Text); 


     using (objConn) 
     { 
      objConn.Open(); 
      SqlDataReader objDR = objCmd.ExecuteReader(); 

      if (objDR.Read()) 
      { 

       Session["uname"] = txtusername.Text; 

       if (objDR["Type"].ToString() == "Member") 
       { Response.Redirect("member.aspx"); } 
       else if (objDR["Type"].ToString() == "Pledge") 
       { Response.Redirect("member.aspx"); } 
       else if (objDR["Type"].ToString() == "Admin") 
       { Response.Redirect("eboard.aspx"); } 



      } 
      else 
      { 


       // btnlogin2.Text = "Failed"; 

      } 
     } 
     btnlogin2.Text = "Logout"; 
    } 
    else if (btnlogin2.Text == "Logout") 
    { 
     btnlogin2.Text = "Login"; 
     txtusername.Visible = true; 
     txtpassword.Visible = true; 
     pnlSideBar.Visible = false; 

     Session.Abandon(); 
     Response.Redirect("index.aspx"); 

    } 
    btnlogin2.Text = "Failed"; 
}

创建你主子属性格式，并使用它的任何地方你的内容页面上，而不是一个变量。母版页属性可以通过在你的aspx页面中添加指令来访问内容页面上的任何位置。
