Hello,

I need to create a menu dynamically where the number of items is variable
but I don't know how to add a single click event handler with a way to
distinguish which item caused the click event:

foreach (MyType obj in ObjectTypes)
{
    MenuItem item = new MenuItem(obj.title);

     // Ideally pass on obj.id to the event handler.
    item.Click += new System.EventHandler(this.typedMenuItem_Click);

    menuItemFileNew.MenuItems.Add(item);
}

Thanks,

Jeronimo

How are about this:

private void typedMenuItem_Click(object sender, EventArgs e)
{
MenuItem mnu=(MenuItem)sender;
switch(mnu.Name)
{
case "MenuName1":
//Do one thing
break;
case "MuniName 2":
//Do other thing
break;
...
...
}
}

Thanks Norman,

The menu items are actually dynamic.. but I can make your suggestion work
by looking for the name on the collection...

thanks.

Hi Jeronimo,

Thanks for your feedback!!

I am glad that you got what you want, but just as "Herfried K. Wagner
[MVP]" and I pointed, the MenuItem does not have a "Name" property, and the
compiler will generate error on building Name property. Actually, Name
property is added by the VS.net designer for only design-time usage. So I
suspect you actually used MenuItem.Text property, yes?

Anyway, if you need further help, please feel free to tell us. I will work
with you. Thanks

'MenuItem' doesn't have a 'Name' property.

Addendum:

> 'MenuItem' doesn't have a 'Name' property.

You may want to use a menuitem extender to extend the 'MenuItem' class with
properties:

Hi Jeronimo,

Thanks for your post!!

I think Norman have provided you one option way: use MenuItem.Text property
to distinguish the items(In design-time, there is no Name property). This
makes sense, because normally, we will not use 2 menuitems with the same
text.

Also, if all the menuitems are the same parent's children, we may use Index
property to determine their position. But I think the Text property options
is better in your situation.
=====================================
Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.
