I think you would be better off using a single ListBox and using the ItemTemplate to generate group headers for each key in an <a href="http://msdn.microsoft.com/en-us/library/bb344977.aspx">IGrouping</a> collection. This would be visually similar to using ListBox.GroupStyle in WPF. <br /><br /> This may not satisfy your user interface requirements, but I think it could be cleaner. The solution you&#39;re looking for could be accomplished (anything can, really) I just don&#39;t know if it would be worth spending the time on if there are potentially cleaner solutions. <br /><br /> Let me know if you need any help creating a DataTemplate as I&#39;ve proposed.http://forums.silverlight.net/forums/thread/242183.aspxFri, 03 Jul 2009 19:08:55 GMTd0d632c8-a6f7-4f68-b0ce-26aaafd62132:242183dnlstffrd0http://forums.silverlight.net/forums/thread/242183.aspxhttp://forums.silverlight.net/forums/commentrss.aspx?SectionID=19&PostID=242183<p>I have items in one listbox that are a grouping of items in a seperate listbox, they are right next to each other, and I&#39;d like to make it so that the items in the left listbox match up with the first item of the group in the right list box.&nbsp; Say for example I have 2 items in the left listbox, and 3 items for each item in the left listbox (so a total of 6), I&#39;d like to space out the items in the left listbox so they line up with the first item of each group in the right listbox.&nbsp; Is there any way to do this?&nbsp; Another issue I&#39;m having is that the items in the right listbox are not necessarily the same size.&nbsp; Thanks in advance for the help. <br /></p>
