To add multiple submenus programmatically

To programmatically add a submenu and another menu within the submenu, complete the following steps:

Add the C1.Win.C1Command namespace to your references in your project, and then declare the namespace in your source file.

To write code in Visual Basic
```
Imports C1.Win.C1Command
```
To write code in C#
```
using C1.Win.C1Command;
```
Double-click the form to create a Form_Load event handler, then insert the following code snippets from the remaining steps into the Form_Load event handler.

Add a C1CommandHolder to hold the menu, then create a new C1MainMenu object.

To write code in Visual Basic

Dim ch As C1CommandHolder = C1CommandHolder.CreateCommandHolder(Me)
Dim mm As New C1MainMenu

To write code in C#

C1CommandHolder ch = C1CommandHolder.CreateCommandHolder(this);
C1MainMenu mm = new C1MainMenu();

Add the main menu control to your form, then create the main menu to hold commands.

To write code in Visual Basic

Me.Controls.Add(mm)
Dim mmenu As C1CommandMenu = CType(ch.CreateCommand(GetType(C1CommandMenu)), C1CommandMenu)

To write code in C#

this.Controls.Add(mm);
C1CommandMenu mmenu = ch.CreateCommand(typeof(C1CommandMenu)) as C1CommandMenu;

Set the text property for the new menu, then add the commandlink to the new main menu.

To write code in Visual Basic

mmenu.Text = "&menu 1"
mm.CommandLinks.Add(New C1CommandLink(mmenu))

To write code in C#

mmenu.Text = "&menu 1";
mm.CommandLinks.Add(new C1CommandLink(mmenu));

Create and set up a menu item under the menu (menu 1), then fill the menu with a command.

To write code in Visual Basic
```
Dim menuitem1 As C1Command = ch.CreateCommand()
```
To write code in C#
```
C1Command menuitem1 = ch.CreateCommand();
```

Add text to the new menu item and add a new c1commandlink to menuitem1.

To write code in Visual Basic

menuitem1.Text = "Menu Item 1"
'add a new c1commandlink to the menuitem1
mmenu.CommandLinks.Add(New C1CommandLink(menuitem1))

To write code in C#

menuitem1.Text = "Menu Item 1";
//add a new c1commandlink to the menuitem1
mmenu.CommandLinks.Add(new C1CommandLink(menuitem1));

Create a new command menu for the second menu item below the menu (menu1), and then add a commandlink for the new menuitem2 menu. Menuitem2 is going to be a menu that contains submenus.

To write code in Visual Basic

Dim menuitem2 As C1CommandMenu = New C1CommandMenu()
menuitem2.Text = "Menu Item 2"
menu.CommandLinks.Add(New C1CommandLink(menuitem2))

To write code in C#

C1CommandMenu menuitem2 = new C1CommandMenu();
menuitem2.Text = "Menu Item 2";
mmenu.CommandLinks.Add(new C1CommandLink(menuitem2));

Create a submenu for the new menuitem2 menu and call it Submenu 1, then add a commandlink for submenu1.

To write code in Visual Basic

Dim submenu1 As C1Command = ch.CreateCommand()
submenu1.Text = "Submenu1"
menuitem2.CommandLinks.Add(New C1CommandLink(submenu1))

To write code in C#

C1Command submenu1 = ch.CreateCommand();
submenu1.Text = "Submenu1";
menuitem2.CommandLinks.Add(new C1CommandLink(submenu1));

Save and run your application. The menus appear like the following at run time:
