分页：

1、先把属性AllowPaging设置为true，
2、pagesize为每一页的行数，PageSize="15".
3、OnPageIndexChanging="gridview1_PageIndexChanging"

protected void gridview1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridview1.PageIndex = e.NewPageIndex;
gridview1.DataBind();

   }  
    ---------------  
    protected void Page\_Load(object sender, EventArgs e)  
    {

        if (!IsPostBack)  
        {  
            if (UserInfo.Username.ToLower() == "ykj")  
                lblPageName.Visible = true;  
        }  
        FillDG();  
        if (!IsPostBack)  
            FillUI();  
    }  
    private void FillDG()  
    {  
        YearStsDetailedData = pc.GetStsdingApplyInfo("");  
    }  
    private void FillUI()  
    {  
        gridYearStsDetailed.DataSource = YearStsDetailedData;  
        gridYearStsDetailed.DataBind();

    }
