有没有一种方法可以在页面加载时分别加载gridviews？

Question

我正在使用C＃和ASP.NET开发一个监视网页，我需要在具有不同数据源的多个Gridview中显示数据。有时，这些数据源之一无法连接或超时，结果页面无法加载。

是否可以在页面加载时（例如在更新面板内）单独加载gridviews，以便如果一个gridviews无法加载，则其余页面不会受到影响？

我尝试在try / catch中包装SqlDataSource \的连接和Gridview的绑定，但是如果到sql源的连接失败，则整个页面将无法加载。

我正在页面加载时执行以下功能

protected void LoadReceivingState(string conString, string SelectCommand) 
    {
        string resultcode = "";
        try
        {
            SqlDataSource_ReceivingState.ConnectionString = ConfigurationManager.ConnectionStrings[conString].ConnectionString;
            SqlDataSource_ReceivingState.SelectCommand = SelectCommand;
            SqlDataSource_ReceivingState.SelectCommandType = System.Web.UI.WebControls.SqlDataSourceCommandType.StoredProcedure;
            SqlDataSource_ReceivingState.DataBind();
            GridView_ReceivingState.DataSourceID = null;
            GridView_ReceivingState.DataSource = null;
            GridView_ReceivingState.DataSource = SqlDataSource_ReceivingState;
            GridView_ReceivingState.DataBind();
            GridView_ReceivingState.Visible = true;
            //PanelAppTracking.Visible = true;
        }
        catch (SqlException ex)
        {
            GridView_ReceivingState.Visible = false;
            
            resultcode = "code: " + ex.Number.ToString() + "Error: " + ex.Message.ToString();
            ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert(resultcode);", true);
            
        }

        
    }
