MenuItems.Count

[genc ymeri]

Hi,
I'm a newbie in C# programming but something very weird is happening to me


I have this menu in a C# form.

"File" and under this {"New","Open", "Exit"} and
"Help" with {"Content", "About"};

when I run this code :

for (short j = 0; (j < mnufrmMain.MenuItems.Count );j++)
{
MessageBox.Show(mnufrmMain.MenuItems[j].Text);
}

only "File" and "Help" show up while all the other menu items e.g.
{"New","Open", "Exit","Content", "About"}; do not show ?

Any explanation or how to browse in each of these items will be greatly
appreciated.

Thank You very much in advance !

The reason is New, Open, Exit are all under mnufrmMain.MenuItems[0].MenuItems. But your loop looks for onl
mnufrmMain.MenuItems. MenuItems form a tree like sructure

Add a second for loop within the first to iterate thru the sub menu items too, and ur problem will be solved

I see.....it's complicated b/c in run time we don't know how many nasted
sub-menus we have. It seems that with the mnufrmMain.MenuItems[0].MenuItems
method I can't loop through all of the sub-sub-sub-submenu items.

Is there any other way to browse all the menuitems created in a C# form at
the run time ?

Thanks a lot.

You could use recursive function to do what you're looking for, something
like you see below:

from whereever in your code, you can call:
ScanMenuItems(this.Menu); // or menufrmMain or whatever

then make sure you have ScanMenuItems defined, something like this:

public void ScanMenuItems(MenuItem menu)
{
for (short j = 0; (j < menu.MenuItems.Count );j++)
{
MessageBox.Show(menu.MenuItems[j].Text);
ScanMenuItems(menu);
}
}

public void ScanMenuItems(Menu menu)
{
for (short j = 0; j < menu.MenuItems.Count; j++)
{
MessageBox.Show(menu.MenuItems[j].Text);
ScanMenuItems(menu);
}
}

You'll need the overloaded definition if you want to start with a Menu
class, which is the top level menu definition for a main menu, and then
recurse into submenus from there down.
