Collections in TList

Reply Contact

An Ad is connected to a TradeCodeId in the database. So in the AdProvider its possible to select all Ads for a given tradecode, when listing TradeCodes i dont want to print the TradeCodes that arent in use, so i was thinking i could use the AdCollection of the TradeCode object, how do I make this happend? But the AdCollection.Count is always 0, so nothing is printed.

Any thoughts?

See code below

TradeCodeDataSource s = new TradeCodeDataSource();
s.Parameters.Add("CategoryID", CategoryID.ToString());
s.SelectMethod = TradeCodeSelectMethod.GetByCategoryID;
TList<TradeCode> tr = (TList<TradeCode>)s.GetEntityList();
TList<TradeCode> List = new TList<TradeCode>();

foreach (TradeCode tc in tr)
{if (tc.AdCollection.Count > 0){List.Add(tc);}}

Hi,

You'll need to DeepLoad your TradeCodeDataSource:

TradeCodeDataSource s = new TradeCodeDataSource();
s.DeepLoad();

That should do the trick.

Cheers,

Evan

YES!

Thanks alot, worked perfectly.

Another question

I only want to show the tradecodes which has a Ad. It must be possible to create a filter for that, but i cant find any good documentation on how to write my own filter class.

Ive written a sorter, "public class TradeCodeSort : System.Collections.Generic.IComparer<TradeCode>"

Cheers
