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....

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.

I think what Justin Angel suggested will help you.

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.

You can try something:

TreeViewItem newParent = (TreeViewItem)TreeView1.SelectedItem;

CheckBox chk = (CheckBox)newParent.Header;

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?

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:

Hi,

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.

Adding Checkbox in Treeview Control....

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.
