C＃代碼：

public void msgcounter() 
    { 

     SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["FBMNGTConnectionString"].ConnectionString); 
     con.Open(); 

     int msgstatusid = 0; 
     while (msgstatusid < 22) 
     { 

      string strquery2 = string.Empty; 



      strquery2 = "select count(Status) as msgcntstatus from MessageApprovalTable where Status = " + msgstatusid + " and ToEmployee_ID =" + Session["Employee_Id"]; 





      SqlCommand cmd2 = new SqlCommand(strquery2, con); 

      SqlDataAdapter sda = new SqlDataAdapter(cmd2); 
      DataSet ds = new DataSet(); 

      sda.Fill(ds); 


      string mgcount = Convert.ToString(ds.Tables[0].Rows[0]["msgcntstatus"]); 


      switch (msgstatusid) 
      { 
       case 11: 

        mgInLabel1.Text = Convert.ToString(mgcount); 

        break; 
       //case 22:

       // break; 
       //case "2":

       default: 
        break; 

      } 





      msgstatusid++; 
     } 

    } 



    protected void Timer1_Tick(object sender, EventArgs e) 
    { 
     counter(); 
     msgcounter(); 
    } 

Answer 1

請添加下面一行的Timer_Tick， 說，菜單ID：MDB; Runat =「服務器」

MDB.attributes.add（「class」，「active-menu」）;

所有頁面你可以採取href的值或頁面名稱有關菜單項
