Merge two contextmenustrips to a single tree node

[libishkb]

I have create two separate contextmenu strips on a windows form. Now i want to display both these combined on to a tree node. Is this possible?
e.g.
First strip: Add, Subtract
Second strip: multiply, divide.

When I right click on a tree node the menu should display Add,subtract,multiply and divide.

I know that
treeView.Nodes[3].Nodes[2].ContextMenuStrip= firststrip;
will disply the first one only. I want to do something like this
treeView.Nodes[3].Nodes[2].ContextMenuStrip= firststrip+secondstrip

You will have to programmatically add all off the ContextMenuItems from menu 1 and menu 2 into a new menu 3, then show that. A simple 'for' loop construct should do it.

I tried this but doesnt work. Do you find any error in this code?

       private ContextMenuStrip mMergeContextMenuStrips(params ContextMenuStrip[] list)
        {
            ///
            /// Merges contextmenustrips  and return a new strip
            ///
            ContextMenuStrip MergeContextMenuStrip = new ContextMenuStrip();
            for (int i = 0; i < list.Length; i++)
            {
                for (int j=0; j< list[i].Items.Count; j++)
                {
                    MergeContextMenuStrip.Items.Add(list[i].Items[j]);
                }
            }
            return MergeContextMenuStrip;
        }

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

*** EDIT ***
If you read my first post, ignore it :D I didn't notice you were passing an array of ContextMenuStrip objects to your method.

Here's a better question, what doesn't work about it? It crashes, merged strip comes out empty, etc..?

In the code above, at the line given below

MergeContextMenuStrip.Items.Add(list[i].Items[j]);

as soon as the item[j] in the list[i] is added to MergeContextMenuStrip this item is deleted from the list[i].items. I dont want this to happen. I just want a copy of this list[i].Items[j] to be pasted in the MergeContextMenuStrip.

Hmm, it looks like those ToolStripMenuItems can only belong to one context menu at a time. You're absolutely correct, when you add from one list to the other, it just removes itself. I dug around MSDN and I don't see why this is.

Either way, all you need to do is create a copy of each one you find and then add it to your merged list.

I found a couple of resources on merging context menus. There's a ToolStripManager.Merge method that does this, but it also seems to remove the items from the source and put them in the new location. So I think your best bet, if you want to maintain both lists, is to create a copy.
