Problem with TreeListView Q1 2010

[Muhammad Djamaluddin]

Hi all,

I am using telerik silverlight TreeListView control from Q1 2010 version, and I found some problems that maybe you guys can help. My simple application display document list in a specified folder and I use TreeListView since its hierarchical structure fit with the file system structure. But there are some problem: 
1. Sometimes the column header is not resized automatically according the size of the first item. It is shown in the picture I attached.
2. Data template to display the item in the first column name consists of an image and a Hyperlinkbutton. I can expands or collapse bu clicking folder image, but how can I do the same when I click a hyperlinkbutton?

Btw, I know TreeListView in Q1 2010 different than Q2 2010, they inherited different class.
But as I know, I can't install Q2 2010 in VS2008 SP1 since it require Silverlight 4, right?
