Adding node context menu with Hiearchical View Model

[Anne Lyon]

Hi,

My TreeView is bound to a ObservableCollection<TreeNode>. Using a HierarchicaldataTemplate the ItemSource is bound to my collection's TreeNodeChildren.
I want to bind a context meny to each node, and must do it in code as the context meny can be different for each node.

But how do I bind the contect menu to the node when the node is a TreeNode and not a RadTreeViewItem?
I cannot cast the current TreeNode to a RadTreeViewItem and hence cannot use the code:
myRadTreeViewItem.SetValue(RadContextMenu.ContextMenuProperty, contMenu);
as TreeNode doesn't have that functionality. I know how to bind properties, like isExpanded, between myTreeNode class and the TreeView, but how do I "bind" a command?

So in code I want to add a new TreeNode to my bound TreeNodeChildren collection, then dynamically create a new context menu and attach this context menu to my newly created TreNode. How do I do that?

Appreciate if somebody has an idea!

Hi Anne,

Try something like this:

RadContextMenu.SetContextMenu(myTreeNode, contMenu);

Hi Igor,

First of all I apologize this question has appeared so many times in the forum as I encountered a Telerik server error which made me believe the postings had been unsuccessful... Please remove duplicate postings if you like...

If I try your solution:
"RadCOntextMenu.SetContextMenu(myCurrentreeNode, contMenu)" I get a syntax error as it doesn't like myCurrentTreeNode as parameter. This is even if the parameter is of type TreeNode which the class my Obserable Collection bound to the treeView consists of.
