get at the product groups & display product group name

Very tough to undestand you question. Unsure | :~

Sorry if I misunderstood you. Is it possible to one more foreach loop inside the one you specified and iterate through ProductGroups collection ?

Yes, for some reason I was try to get down to the 3rd level by only using two for each loops! (Dont ask - a million n 1 things going on here at the mo')

So now I have these loops:-

foreach(Site site in Sites)<br />
{<br />
     //write info here for site<br />
     foreach (ProductGroup productGroup in site.ProductGroups)<br />
            {<br />
                //write info here for product group<br />
                foreach (Product product in productGroup)<br />
                {<br />
                     //write info here for product<br />

Only 1 issue now, when I try & compile I get this error:-

foreach statement cannot operate on variables of type 'KSS.PriceNet.Shared.EntityModel.ProductGroup' because 'KSS.PriceNet.Shared.EntityModel.ProductGroup' does not contain a public definition for 'GetEnumerator'.

I haven't seen this before, any ideas?

Because ProductGroup is not collection class. So foreach won't work. I think 3rd forloop has some problem. It could be like

foreach (Product product in productGroup.Products)
{

Right ?

Something like this?

foreach (Site site in sites)
{
   foreach ( ProductGroup aGroup in site.ProductGroups)
   {
       foreach (Product prod in aGroup.Products)
       {

       }
   }
}

Do you mean FavIcon ? Add the following tag to your page head

<link rel="shortcut icon" href="/favicon.ico" />

You should keep the favicon.ico in the specified path.

Paging in GridView

Hi, I have a aspx page with a GridView with Paging and Sorting enabled.
I opened a SQL Profiler to check at what times the stored procedure which fetches data to bind to GridView is being called.

When I go to another page and come back to the GridView page then the procedure does not get called. But when I use the paging feature of the GridView and try to see next 10 records on the second page of GridView, my profiler shows a call to the stored procedure which always returns say 100 rows.

If my procedure at the first place did give the GridView all the 100 rows then why upon changing GRid Pages the procedure gets called again.

NOTE: I have bound the GridView using SqlDataSource.

U have to use the Gridview_paging Event..in this u have find the currentindex of the Gridview give this index to the newIndex of the Gridview...then bind the Grid again.

u have to creat function that binds the grid
ie BindGrid();
call it on load;
then creat gridview_pageindexchanging
and put in it
{
gv.PageIndex=e.New index;
BindGrid();
}

You should take a good book and learn how web pages works.

HTTP is a stateless protocol. Gridview fetches all the rows when it is binded at the very first time. When you press the next button on pager, entire page will be posted to the server which removes all the values binded on the last page. So it will fetch all those data again and bind it to grid view, Pageindex will be checked then and it moves to the page specified.

This will make performance issues when you are working with large set of data's. So I prefer to do custom paging always, by fetching required number of rows from DB.

Hope this helps

Tks Navaneeth. Your answer nelped a lot. I will try and implement caching on my collection that binds to the GridView to improve performance. Although I guess custom paging is a much better option for huge no of records.

Instead of caching, you could go for custom paging. Caching might show weird results for users browsing site at same time.
