Hello all,

 Does anybody know how to customize TreeView for showing connection lines between items (like in most of other treeview controls)?

I spent a lot of time for this issue but could not find any ideas in the web and own efforts didn't get satisfied result to.

Thanks...

The TreeView control currently does not support showing connection lines between Items.

This is done for WPF Compatibility since the WPF TreeView does not support drawing connection lines. We'd like to give you the option of running your Silverlight XAML on the desktop through WPF and adding features on changing the XAML API breaks that ability.

We are looking into options of adding various abilities to TreeView (multi select, connection lines, Drag & drop and others).
Please feel free to vote on adding connection lines for TreeView at the following codeplex issue if you're passionate about adding it to Silverlight Toolkit future versions: http://www.codeplex.com/Silverlight/WorkItem/View.aspx?WorkItemId=851 

Personally, I've been playing around with editing the template or creating a "mask" on top of the TreeView templates that draw the lines. But without much success.

 I've alredy voted before and waiting with hope for positive result.

IAE Thanks.

Its a shame these features are not included as standard, I've been using the liquid Silverlight treeview for a while, whilst the node content has to be text it does support multi-select, connector lines, drag and drop and is a great control that fills the gap until these features are included in the official Silverlight 2 treeview.

JustinAngel - What do you mean by: "We'd like to give you the option of running your Silverlight XAML on the desktop through WPF and adding features on changing the XAML API breaks that ability." Are you talking about some future goal? Or is something that can be done already? How will it handle Silverlight Tookit controls which are not in WPF?
