Using ObjectCollection in Silverlight

This is stemmed from another question I had where the solution had me using ObjectCollection. I have never used an ObjectCollection before and was wondering if anyone knew where I could find more info on it?

Everywhere I look talks briefly at best about the ObjectCollection, but never really says much about it. I know it is another control, I开发者_StackOverflow'm just not sure what it does exactly.

From what I can gather it is more or less a "holder" or container for variables used in the code-behind. Or possibly a table of data?

The ObjectCollection is provided by the Silverlight Toolkit. If you have that installed open the Documentation .chm file via the programs menu, its documented in there.

It isn't actually a control even though it is placed in the System,Windows.Controls namespace. In fact all it is a standard generic Collection<T> defined as:-

 ObjectCollection : Collection<Object> { }

The only reason a separate class is needed at all is because you can't describe generic types in Xaml.
