500pts: Get a reference to a menuitem in ContextMenu (winforms)

Hi there,

Can anyone help, i am trying to get a reference to a menuitem in ContextMenu_Popup, currently i am using the index which is really bad as the index can change.. like this..

ContextMenu.MenuItems[11].Enabled = false;

I have added the menuitem like so but i don't see an NAME item or anything that i can replace the index with... Any ideas?

                  MenuItem inserter =new MenuItem();
                  inserter.Shortcut = Shortcut.Ins;
                  inserter.ShowShortcut = true;
                  inserter.Text = "Insert";
                  inserter.Click += new EventHandler(inserter_Click);
                  
                  viewer.ContextMenu.MenuItems.Add(4,inserter);

Thanks in advance

ian

Why not create "inserter" as class data member?

You wanted this?


                  MenuItem inserter = new MenuItem();
                  inserter.Shortcut = Shortcut.Ins;
                  inserter.ShowShortcut = true;
                  inserter.Text = "Insert";
//Name is the Key
                  inserter.Name = "ins";
                  inserter.Click += new EventHandler(inserter_Click);

                  ContextMenu ctx = new ContextMenu();
                  viewer.ContextMenu = ctx;  //            0 = index
                  viewer.ContextMenu.MenuItems.Add(0, inserter);
                  viewer.ContextMenu.MenuItems[0].Enabled = false;
                  viewer.ContextMenu.MenuItems["ins"].Enabled = true;
                  MessageBox.Show(viewer.ContextMenu.MenuItems["ins"].Name);

Sorry, forgot to explain the bottom half.

viewer.ContextMenu.MenuItems[] has two methods of reference
int i
string key
both for index.   The "key" is the name of the menuItem.

I just ran and compiled this on VS 2005, .NET 2.0 and it worked.  I hope you are using that, else I'm not 100% sure if it will work with 2003.

Okay, I just checked on 2003 on my old system, there is no name attribute, however.  You can still refer to your context menu items by name, if you don't destroy the object that creates them.
i.e.

In your main form, declare your menuItems as global to the form e.g.

private MenuItem inserter = new MenuItem();

//Then this is what I used to test with:
                                           private void Form1_Load(object sender, System.EventArgs e)
            {
                  inserter.Shortcut = Shortcut.Ins;
                  inserter.ShowShortcut = true;
                  inserter.Text = "Insert";
                  inserter.Click +=new EventHandler(inserter_Click);
                  listView1.ContextMenu = contextMenu1;
                  listView1.ContextMenu.MenuItems.Add(0,inserter);
            }

            private void button1_Click(object sender, System.EventArgs e)
            {
                                                               //changing this, it changes the state.
                  inserter.Enabled = !inserter.Enabled;
            }

I totally misunderstood your hint, I was thinking in 2.0, so that didn't appear as a solution to the problem.  Only after I wrote the 2.0 solution I realised he meant 1.1, so I never read your post after that.
 My apologies about this, though, elaborating your idea wouldn't have hurt =/  I wouldn't have glanced over it so fast.

Don't worry, it was more question as hint.
