Contextmenu when moving to Prometheus

[FU]

I have a problem moving the contextmenus from the ASP.NET-treeview to the ASP.NET AJAX-treeview.

I loaded the contextmenus for differenct nodetypes like this:
myTree.ContextMenuContentFile = "AllMenus.xml";

It seems I have to split the AllMenus.xml into an xml-file for each nodetype and load it like this:
RadTreeViewContextMenu contextMenu = new RadTreeViewContextMenu();

contextMenu.LoadContentFile("Menu1.xml");
myTree.ContextMenus.Add(contextMenu);

contextMenu.LoadContentFile("Menu2.xml");
myTree.ContextMenus.Add(contextMenu);

contextMenu.LoadContentFile("Menu3.xml");
myTree.ContextMenus.Add(contextMenu);

But when I rightclick on any node it shows the standard IE-contextmenu. What am I doing wrong or not doing at all?

Hi Mickey13,

To display different context menu for each node you should set the ContextMenuID properties of the nodes as shown in the attached sample project. Please download the files and give them a go.

I hope this will get you started.

I already did this as it works the same way in the RadControls for ASP.NET-treeview. My problem is that if I replace the existing/working RadControls for ASP.NET-treeview with the new RadControls for ASP.NET AJAX-treeview I can't get it to show the context-menu.

It seems I have two problems:
1. If I load several XML-files as in my previous post, I get a JavaScript-error "Sys.InvalidOperationException: A control is already associated with the element.".

2. If I only load one XML-file I don't get any errors but also no contextmenu.

Hello Mickey13,

There have been changes in the built-in context menu of the treeview. Therefore, I attached a sample project that shows the needed approach. I used your logic so that the project can get you started. Have you run the project I attached? Can you apply the same approach to your application?
