Nesting using repeater in repeater

User controls that browse categories in a generic Web site are typically located on the left side of most asp.net pages, enabling users to quickly find products by category. Recently met a customer, because the product on his website is not many, so the request in the original category browsing based on the product added. A more convenient, and secondly lengthened the length of the left navigation bar to make the page more coordinated. The original category navigation bar is implemented by repeater, now need to add to each category of commodity information, so I thought of the original repeater nested repeater. The implementation interface is as follows:


Front Page section:
<asp:repeater id= "rptcategories" runat= "Server" >
<HeaderTemplate>
<table width= "100%" border= "0" cellspacing= "0" cellpadding= "0" >
</HeaderTemplate>
<ItemTemplate>
<!--category name-->
<tr><th><%# DataBinder.Eval (Container.DataItem, "TypeName")%></th></tr>
< product--> under the category of!--
<asp:repeater id= "rptproduct" runat= "Server" >
<ItemTemplate>
<tr><td><a href= ' productinfo.aspx? id=<%# DataBinder.Eval (Container.DataItem, "ID")%> ' ><%# DataBinder.Eval (Container.DataItem, " ProductName ")%></a></td></tr>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

Background Code section (partial code):
When binding category name, the product under the binding category
private void Rptcategories_itemdatabound (object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
Bll. Products Products =new BLL. Products ();
if (E.item.itemtype = = ListItemType.Item | | E.item.itemtype = = ListItemType.AlternatingItem)
{
Repeater rptproduct = (Repeater) e.item.findcontrol ("rptproduct");
Find the data item that the taxonomy repeater associated with
DataRowView ROWV = (DataRowView) e.Item.DataItem;
Extract Category ID
int Categorieid = Convert.ToInt32 (rowv["ID"]);
According to the classification ID query the products under this category, and binding products repeater
Rptproduct.datasource = products. Getproductsbycategorieid (Categorieid);
Rptproduct.databind ();
}
}
