Hi,
I am looking for a source code to add a check box in a treeview control and when selected in one of the parent node it has to select all the child nodes and vice versa.

You can have a look at this link:
http://silverlight.net/blogs/justinangel/archive/2008/11/18/silverlight-toolkit-treeview-treeviewitem-amp-hierarchaldatatemplate.aspx
or you can do something like this:
Parent.Header = "Parent";...if(Child1.Items.Count > 0) Child1.Header = "Child1";else Child1.Header = new CheckBox();
do looping for treeview control to make all the child nodes checked.
Hope this helps you.

I strongly recommend you read my TreeView article previously linked here. Basically, You'll need to have a CheckBox databound to some value in a HierarchicalDataTemplate.
We've got a sample for that up on our official Silverlight Toolkit samples: http://silverlight.net/samples/sl2/toolkitcontrolsamples/run/default.html?path=Controls|TreeView|Using%20CheckBoxes

I'm also trying to achieve this but my datacontext items don't have a value which I could bind to my checkbox. I want to do another stuff when the checkbox is clicked. Everything else is working for me but I can't seem to find the checkbox control within the TreeViewItem. Do I need to find a way to bind the checkbox to a value or is there a way to find the Checkbox control within the treeviewitem?

You can try something:
TreeViewItem
CheckBox chk = (CheckBox)newParent.Header;

This didn't work. I have the datacontext item in the Header, no checkbox. I have a datatemplate with a stackpanel and a checkbox and contentpresenter inside it.

I think what Justin Angel suggested will help you.

Yes, that helped. I'm using RIA Services but I extended the EF model class with a custom property and got it binded for the checbox. Now everything works fine. Thanks again.

You could also use the TreeView control from VectorLight http://www.vectorlight.net/controls/tree_view.aspx
It has some very useful features, and also the ones you mentioned....
