I have one contextmenustrip control associated with treenode. I have created one menu item in contextmenustrip manually in the form itself(for example named as "Assign").
Now I want to add sub menu items whenever user clicks this Assign item, it will create a list of users name as a sub menu item with checked or unchecked option.
For example, once user clicked Assign then I want to show the user name dynamically.
To add an item, you would call
myContextMenuStrip.Items.Add("Item title", null, myClickHandler);
To add a sub-menu, you take an existing item and do the same to it:
(myContextMenuStrip.Items[0] as ToolStripMenuItem).DropDownItems.Add(...)
