如何委托telerik网格视图从每个子页面的父页面调用常用方法？

我Telerik Gridview用于显示记录列表,我有超过10页我正在使用此gridview与以下常见事件代码复制粘贴(有一些小的更改)在所有这些页面上:

protected void Page_Load(object sender, EventArgs e)
{
    DisplayRecords()
}

public void DisplayRecords()
{
    //Grid view names are different on different pages.
    GridView1.DataSource=Fetching records from database.
    GridView1.DataBind();
}

protected void GridView1_SortCommand(object sender, GridSortCommandEventArgs e)
{
    DisplayRecords()
}

protected void GridView1_PageIndexChanged(object sender, GridPageChangedEventArgs e)
{
    var index = e.NewPageIndex;
    DisplayRecords()
}

protected void GridView1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
{
    var size = e.NewPageSize;
    DisplayRecords()
}

这是我的一页继承自以下页面:

public partial class LoadSettings : ParentPage
{
    //Load events and other events
}

[Serializable]
public class ParentPage: RadAjaxPage
{

}

Page 1:**ttt.aspx**
public void DisplayRecords()
    {
        //Grid view names are different on different pages.
        GridView1.DataSource=this.GetAlltttData()
        GridView1.DataBind();
    }

    public DataTable GetAlltttData()
            {
                using (var context = new MyDataContext())
                {
                    var data = from c in context.ttt select c;
                    return MyDataContext.LINQToDataTable(data);
                }
            }


Page 2:**bbb.aspx**
public void DisplayRecords()
    {
        //Grid view names are different on different pages.
        GridView1.DataSource=this.GetAllbbbData()
        GridView1.DataBind();
    }

    public DataTable GetAllbbbData()
            {
                using (var context = new MyDataContext())
                {
                    var data = from c in context.bbb select c;
                    return MyDataContext.LINQToDataTable(data);
                }
            }

protected void rgbbb_SortCommand(object sender, GridSortCommandEventArgs e)
        {
           DisplayRecords()
        }
protected void rgbbb_PageIndexChanged(object sender, GridPageChangedEventArgs e)
        {
            var index = e.NewPageIndex;
            DisplayRecords()
        }

 protected void rgbbb_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
        {
           var size = e.NewPageSize;
           DisplayRecords()
        }

那么这可能是我可以将所有这些事件放在这个ParentPage页面中,只是从每个子页面调用而不是用这个事件污染我的每一页？

注意:在我的一些页面中,此DisplayRecords方法可以包含一些参数,但所有事件都是常见的.
