Using ObjectCollection in Silverlight

Question

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'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? I'm not sure. Any and all information on the ObjectCollection control is much appreciated!

Thank you in advance!

Answer 1

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.
