Need quick help...

[Jacek Jurkowski]

I have to add a property to an object that is already
allive. The problem is that I'm creating MainMenu
from a definition file ... enyway , there is a need to add
each menu item some extra informations. I used to
do that using Tag property of an objects but ManuItem
doesn't have anything like that. So how to add a Tag property
to a MenuItem?

Try using a Hashtable to associate the menu item object as a key with some
data that you define.

Hi Jacek,

First of all, I would like to confirm my understanding of your issue.
From your description, I understand that you wants to add extra information
to a menuitem by using Tag Property which the menutiem does no have.
Have I fully understood you? If there is anything I misunderstood, please
feel free to let me know.

I think we can create a new class derived from MenuItem and add a Tag
proterty to the class.

public class MyMenuItem : MenuItem
{
object _Tag;
public object Tag
{
get
{
return _Tag;
}
set
{
_Tag = value;
}
}
}

private void Form1_Load(object sender, System.EventArgs e)
{
MainMenu menu = new MainMenu();
this.Menu= menu;
MyMenuItem menuItem1 = new MyMenuItem();
menuItem1.Text="hello";
menuItem1.Tag="fsdf";
menuItem1.Click+=new EventHandler(menuItem1_Click);
menu.MenuItems.Add(menuItem1);
}

private void menuItem1_Click(object sender, EventArgs e)
{
MessageBox.Show("menuItem1.Tag: " + (this.Menu.MenuItems[0] as
MyMenuItem).Tag.ToString());
}


Please apply my suggestion above and let me know if it helps resolve your
problem.

This soloution is valid but the trouble with doing this is that the derived
class cannot be used at design time.

Hi Jacek,

As Bob said, if you wants to do the job in design time, I think you can
adopt Bob's suggestion.
