C# 在asp.net中触发sqldependency onchange，但asp.net控件中没有刷新

Sqldependency

onchange在

asp.net

中成功触发，我能够在

Dataset

中获得更新的数据，但当它将

Dataset

绑定到

Gridview

时，它不会刷新自身

此外，当触发

SqlDependency

事件时，不会触发

asp.net

页面生命周期事件

                                                                                           protected void dependency_OnChange(object sender, SqlNotificationEventArgs e)
    {
        SqlDependency dependency = (SqlDependency)sender;
        dependency.OnChange -= dependency_OnChange;

        UpdatePanel1.Update();
        connstr = "server=66.226.75.158\\SQLEXPRESS;database=sqldependencydb;User id= sqldependencyuser01;Password= yewtee#123";
        string ssql = "select EmployeeID,FirstName from dbo.EmployeeList";
        if (connection == null)
            connection = new SqlConnection(connstr);
        if (command == null)
            command = new SqlCommand(ssql, connection);

        if (myDataSet == null)
            myDataSet = new DataSet();
        myDataSet.Clear();
        command.Notification = null;
        Label1.Text = System.DateTime.Now.ToString();
        adapter = new SqlDataAdapter(command);
        adapter.Fill(myDataSet, "dbo.EmployeeList");
        GridView1.DataSource = myDataSet;
        GridView1.DataMember = "dbo.EmployeeList";
        GridView1.DataBind();



    }

我想你需要把

UpdatePanel1.Update（）放进去

after

GridView1.DataBind（）有什么解决办法吗？有什么解决办法吗？？
