RadTreeView.RadContextMenu is obsolete

[Jill-Connie Lorentsen]

After upgrading to Q2 2009 SP1 I have problems with the drop down menu assigned to my tree view (RadTreeView.RadContextMenu = RadDropDownMenu)

I get an error saying that the RadTreeView.RadContextMenu is obsolete, and I should use the RadContextMenuManager instead.

Trying to compile results in an error "Cannot implicitly convert type 'Telerik.WinControls.UI.RadDropDownMenu' to 'Telerik.WinControls.UI.RadContextMenu' "

I do a lot of formatting on my RadDropDownMenu in code, so I hope there is a way to keep using it in my tree view?

I've done it "the hard way" and implemented use of RadContextMenuManager and RadContextMenu

Hello Jill-Connie Lorentsen,

Generally, you can just change the type of your RadDropDownMenu to RadContextMenu and your code will compile correctly. For example, if you code is:

RadDropDownMenu dropDown = new RadDropDownMenu();

dropDown.Items.Add(new RadMenuItem("First"));
dropDown.Items.Add(new RadMenuItem("Second"));
dropDown.Items.Add(new RadMenuItem("Third"));

this.radTreeView1.RadContextMenu = dropDown;

and you update to Q2 2009 SP1, you need to change it this way:

RadContextMenu dropDown = new RadContextMenu();

dropDown.Items.Add(new RadMenuItem("First"));
dropDown.Items.Add(new RadMenuItem("Second"));
dropDown.Items.Add(new RadMenuItem("Third"));

this.radTreeView1.RadContextMenu = dropDown;

However, please note that as the warning says, the RadTreeView.RadContextMenu property will be removed in the next major release and you will need the RadContextMenuManager in order to create a RadContextMenu property.

If you have additional questions, feel free to contact me.
