关于分页控件AspNetPager中的EndRecordIndex属性
第一次加载是页码和分页都是正确的，repeater控件显示的是一条数据
当我输入的查询条件得到的是一条数据时，也没错；
当我打算再次显示多条数据时，repeater控件得到的就是一条数据，而且调试的EndRecordIndex=1，
帮我看看代码哪有漏洞，实在找不出来啦？
表示层的内容：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GetddlregionSource(); //区域的数据源
string pre = txtpredate.Value + " 00:00:00";
string next = txtnextdate.Value + " 23:59:59";
string regions = ddlregion.SelectedItem.Text;
AspNetPager1.RecordCount = JICHAManager.GetAspNetPagerCount(AspNetPager1.StartRecordIndex, AspNetPager1.EndRecordIndex,pre,next,regions); //加载时得到总页数
GetAspNetPagerSource(); //得到所有的记录
}
}
#region “得到地区的数据源”
public void GetddlregionSource()
{
IList<SEC_REGION> list = SEC_REGIONManager.GetAllRegion();
ddlregion.DataTextField = "REGION_NAME";
ddlregion.DataValueField = "REGION_ID";
ddlregion.DataSource = list;
ddlregion.DataBind();
ddlregion.Items.Insert(0, new ListItem("--全部--", "-1"));
