How to loop through controls in a DocumentWindow?

Hi,

I've been trying to do something fairly simple (I thouight). Basically I want to loop through all the controls that are within a DocumentWindow. I thought the C# code would be something like:

// testDocumentWindow, DocumentWindow containing other controls

foreach (object obj in testDocumentWindow.Items)
{
//do something
}

There are no attributes for testDocumentWindow.Controls, testDocumentWindow.Children or testDocumentWindow.Items.

Could someone please help.

Thanks,

Ryan.
