C# 通过ObjectDataSource进行分页的中继器

是否可以使用ObjectDataSource的：

EnablePaging="true" 
MaximumRowsParameterName="maximumRows" 
StartRowIndexParameterName="startRowIndex" 
SelectCountMethod="TotalNumberOfProducts">

或者我必须在代码隐藏中设置所有值，并将其传递给ObjectDataSource的参数：

<SelectParameters>
  <asp:Parameter Name="startRowIndex" DbType="Int32" DefaultValue="0" />
  <asp:Parameter Name="maximumRows" DbType="Int32" DefaultValue="10" />
</SelectParameters>

因为中继器不支持分页，您无法使用Objectdatasource实现这一点。。。
但如果要进行分页，则必须在代码级别处理。。。
我在代码级别对datalist进行了分页，因为datalist也不支持分页。。。
如果您需要代码，我可以为您提供。。。。 当您想将数据绑定到中继器时，请调用bindRpt方法，注意：这个示例处理“下一步”、“上一步”、“第一步”按钮的分页。。。。如果有什么不清楚的，请告诉我

private void BindRpt()
{
    PagedDataSource ObjPds;
    ObjPds = DoPagging((DataTable)ViewState["dtblProducts"]);
    dlProducts.DataSourceID = "";
    dlProducts.DataSource = ObjPds;
    dlProducts.DataBind();
}
protected PagedDataSource DoPagging(DataTable dt)
{
    if (dt.Rows.Count > 0)
    {
        lblNoRecord.Visible = false;
        pnlNavigation.Visible = true;
        pnlTopNavigation.Visible = true;
    }
    else
    {
        lblNoRecord.Visible = true;
        pnlNavigation.Visible = false;
        pnlTopNavigation.Visible = false;
    }
    PagedDataSource ObjPagDataSource = new PagedDataSource(); //'declares the paged data source
    ObjPagDataSource.DataSource = dt.DefaultView;

    ObjPagDataSource.AllowPaging = true;
    ObjPagDataSource.PageSize = PgSize;
    if (hdfPageIndex.Value == "SetLastPageIndex")
    {
        CurrentPageIndx = ObjPagDataSource.PageCount - 1;
        ObjPagDataSource.CurrentPageIndex = ObjPagDataSource.PageCount - 1;
    }
    else
    {
        ObjPagDataSource.CurrentPageIndex = CurrentPageIndx; 
    }

    if (ObjPagDataSource.PageCount > 1)
    {
        if (ObjPagDataSource.IsFirstPage == true)
        {
            ibtnLast.Enabled = true;
            ibtnFirst.Enabled = false;

是的，请这样做，我会很感激的。如果我没有弄错的话，这个解决方案在表示层而不是数据访问层上进行分页，对吗？是的，你是对的，如果你想在数据访问层上进行分页，最好是在存储过程层上进行…：）
