Repeater嵌套问题，可以简单的理解为双重for循环。原理其实是一样的，下面是我在项目中摸索的，编译通过，效果明显。呵呵，好了

源码如下：

[c-sharp] view plaincopyprint?

        </asp:Repeater>

下面是后台代码的绑定外层Repeater数据方法：

[c-sharp] view plaincopyprint?

/// <summary>
/// 绑定Repeater数据源
/// </summary>
protected void GetBind()
{
Repeater1.DataSource = BindData();
Repeater1.DataBind();
}
///// <summary>
/// 绑定数据源
/// </summary>
/// <returns></returns>
protected IList BindData()
{
using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext())
{
var query_WineParty = from query_wineHeader in ctx.Nop_WinePartyHeader
join query_winePlotos in ctx.Nop_WinePartyPhotos
on query_wineHeader.WinePartyHeaderId equals query_winePlotos.WinePartyHeaderId
//join query_winePartyProduct in ctx.Nop_WinePartyProduct

join query_wineplace in ctx.Nop_WinePartyPlace
on query_wineHeader.WinePartyHeaderId equals query_wineplace.WinePartyHeaderId
select new
{
query_winePlotos.WinePartyPhotosId,
query_wineHeader.WinePartyHeaderId,
wineHeaderName = query_wineHeader.Name,
query_wineplace.Quantity,
ImageUrlPlotos = query_winePlotos.ImageUrl == null ? "" : "../" + query_winePlotos.ImageUrl,
query_winePlotos.Description,
query_wineHeader.ActivityDate,
//query_Product.Name,
//ImageUrlPicture = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false)
};
return query_WineParty.ToList();
}
}

/// <summary>
        /// 绑定Repeater数据源
        /// </summary>
        protected void GetBind()
        {
            Repeater1.DataSource = BindData();
            Repeater1.DataBind();
        }
        ///// <summary>
        /// 绑定数据源
        /// </summary>
        /// <returns></returns>
        protected IList BindData()
        {
            using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext())
            {
                var query_WineParty = from query_wineHeader in ctx.Nop_WinePartyHeader
                                       join query_winePlotos in ctx.Nop_WinePartyPhotos
                                       on query_wineHeader.WinePartyHeaderId equals query_winePlotos.WinePartyHeaderId
                                       //join query_winePartyProduct in ctx.Nop_WinePartyProduct
                                       //on query_wineHeader.WinePartyHeaderId equals query_winePartyProduct.WinePartyHeaderId
                                       //join query_Product in ctx.Nop_Product
                                       //on query_winePartyProduct.ProductId equals query_Product.ProductId
                                       //join query_product_picture in ctx.Nop_ProductPicture
                                       //on query_Product.ProductId equals query_product_picture.ProductID
                                       join query_wineplace in ctx.Nop_WinePartyPlace
                                       on query_wineHeader.WinePartyHeaderId equals query_wineplace.WinePartyHeaderId
                                       select new
                                       {
                                           query_winePlotos.WinePartyPhotosId,
                                           query_wineHeader.WinePartyHeaderId,
                                           wineHeaderName = query_wineHeader.Name,
                                           query_wineplace.Quantity,
                                           ImageUrlPlotos = query_winePlotos.ImageUrl == null ? "" : "../" + query_winePlotos.ImageUrl,
                                           query_winePlotos.Description,
                                           query_wineHeader.ActivityDate,
                                           //query_Product.Name,
                                           //ImageUrlPicture = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false)
                                       };
                return query_WineParty.ToList();
            }
        }

下面是绑定内嵌Repeater数据集方法：

[c-sharp] view plaincopyprint?

/// <summary>
/// 在项被数据绑定后，绑定内嵌Repeater
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater rpColumnNews = (Repeater)e.Item.FindControl("Repeater2");
string[] newrowv = e.Item.DataItem.ToString().Split(new char[] { ',' });
//提取ID 格式：——>wineHeaderID=1 截取字符串
string wineHeaderID = Convert.ToString(newrowv[1]);
int index = wineHeaderID.LastIndexOf("=");
rpColumnNews.DataSource = GetNop_WinePartyProduct(int.Parse(wineHeaderID.Substring(index + 1)));
rpColumnNews.DataBind();
}
}
/// <summary>
/// 绑定内嵌Repeater数据源
/// </summary>
/// <returns></returns>
protected IList GetNop_WinePartyProduct(int winePartyHeaderID)
{
using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext())
{
var query = (from query_winePartyProduct in ctx.Nop_WinePartyProduct
join query_Product in ctx.Nop_Product
on query_winePartyProduct.ProductId equals query_Product.ProductId
join query_product_picture in ctx.Nop_ProductPicture
on query_Product.ProductId equals query_product_picture.ProductID
where query_winePartyProduct.WinePartyHeaderId == winePartyHeaderID
select new
{
query_Product.Name,
ImageUrl = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false)
}).Take(4);
return query.ToList();
}
}

/// <summary>
        /// 在项被数据绑定后 ， 绑定内嵌Repeater
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rpColumnNews = (Repeater)e.Item.FindControl("Repeater2");
                string[] newrowv = e.Item.DataItem.ToString().Split(new char[] { ',' });
                //提取ID  格式：——>wineHeaderID=1 截取字符串
                string wineHeaderID = Convert.ToString(newrowv[1]);
                int index = wineHeaderID.LastIndexOf("=");
                rpColumnNews.DataSource = GetNop_WinePartyProduct(int.Parse(wineHeaderID.Substring(index + 1)));
                rpColumnNews.DataBind();
            }
        }
        /// <summary>
        /// 绑定内嵌Repeater数据源
        /// </summary>
        /// <returns></returns>
        protected IList GetNop_WinePartyProduct(int winePartyHeaderID)
        {
            using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext())
            {
                var query = (from query_winePartyProduct in ctx.Nop_WinePartyProduct
                             join query_Product in ctx.Nop_Product
                             on query_winePartyProduct.ProductId equals query_Product.ProductId
                             join query_product_picture in ctx.Nop_ProductPicture
                             on query_Product.ProductId equals query_product_picture.ProductID
                             where query_winePartyProduct.WinePartyHeaderId == winePartyHeaderID
                             select new
                             {
                                 query_Product.Name,
                                 ImageUrl = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false)
                             }).Take(4);
                return query.ToList();
            }
        }

绑定数据方法，大同小异，大家可以根据自己的需求更改所需方法；

顺便把Repeater分页方法也粘贴出来吧。希望对大家有帮助！

[c-sharp] view plaincopyprint?
