Hi Jason,

          thanks for your fast response, however i look a the souce code path you mention which doesnt contain any souce code ( C:\Program Files\Infragistics\NetAdvantage for WPF 2008 Vol. 2) . actually which is pretty cool if something can share an execuable application project for download, when i look at the showcase presentation,which is wonderful and those are able to fullfill my requirement, however im not open like a solution file to run it on my local PC to learn from the sample code.

     when i purchase for these components, my boss is expecting the almost the same output, which is something i need to archive it especially the showcase sales manager layout and design pattern, which is really attracting me.

    if possible, i would like your big hand to get some best pratice souce code which may help all the developers fast to learn for those components.

  also, i realize that the "feature browser" contain a toybox library, which looks like doesnt a stardard dll come from the box, and the sample tab doesnt show the output as well.

 sorry for this long message and please give soeme advise,

thanks !
