Question

I am using WinForms, i have tried TreeView and it almost have similar structure to the MenuStrip, only one thing i can’t figure out is how to insert a ToolStripMenuItem as a sub item. Is there anyway maybe like:

//There is no Items.Add() after you find the toolstripitem array
MenuStrip.Items.Find("key").Items.Add().
//Same thing
ToolStripMenuItem.Items.Find("key").Items.Add().

I have tried almost everything and there is nothing like that at all, maybe someone could help me.

Answer 1

Try this code.

        var item = menuStrip1.Items["toolStripMenuItem1"];

        ToolStripMenuItem newItem = new ToolStripMenuItem("my new item");
        var index = menuStrip1.Items.IndexOf(item);
        menuStrip1.Items.Insert(index + 1, newItem);

Edit: Updated with new code.

Edit2: This code will add the new menu item inside as dropdown item.

        ToolStripMenuItem item = (ToolStripMenuItem)menuStrip1.Items["toolStripMenuItem1"];

        ToolStripMenuItem newItem = new ToolStripMenuItem("my new item");
        item.DropDownItems.Add(newItem);
