Hi Yanko,

Thank you very much for your reply. I have tried to use the link you sent but have failed miserably. I am new to Silverlight and that makes it a bit difficult for me. Will you please be able to convert the attached to above work as expected. I will be extremely grateful.

Kind regards.

Hi Leslie,

Thank you for your reply. I created a sample application(OutlookBar_GroupBinding.zip) that has the same data as yours.

Let me know, if you need any further assistance on this matter.

Hi Yanko, Thank you very much for your quick support. This is absolutly perfect. I really appreciate this. I have a last question. Will you please show me how I can implement a click event on the tree using MVVM.

Kind regards.

Hi Leslie,

Thank you for your reply. I am attaching a modified version of my sample application(OutlookBar_GroupBinding_2.zip) where I have handled the left mouse click event of the XamDataTree in MVVM using Command.

Let me know, if you need any further assistance on this matter.

Hi Yanko, Thank you very much for your swift response. I appreciate your time. I have a slight problem with the example you sent. It seems to work but not as expected. For instance, the click event fires when I click anywhere within the Tree. A more appropriate example would be to fire only when a valid treeview item is clicked on. And also the Message should fire from a function as the command should be tied to a function.

Thank you very much.

Kind regards.

Hi Nadeem,

Thank you for your reply.  If you would like to fire an event when a node is selected, you could try the ‘ActiveNodeChanged’ event. You can modify the command implementation as you desire in order to follow your scenario.  This is just an example on how you could bind command instead of handle event in code-behind.

Let me know, if you need any further asssitnce on this matter.

Hi Leslie,

Let me know, if you need any further assistance on this matter.

Hi Yanko,

This is perfect. thank you very much for your help.

Kind regards.

Hi Leslie,

Thank you for your reply. I have been looking into your requirement and I changed my approach. I believe that it would be better to use Behavior instead of Command in this scenario.

I am attaching a modified version of my sample application(OutlookBar_GroupBinding_Modified.zip).

Let me know, if you need any further assistance on this matter.

Hi Yanko,

Thank you very much for your reply above. Sorry to be a pain. I am having a bit difficulty achieving the scenario above. For instance, using MVVM, I would like a function to return the title or text on the treeview item clicked on as and when a treeview item is clicked. Would you please be able to modify the example you attached to achieve this?

Thank you.
