How to loop through top level contextmenustrip dropdown items?

[rfresh737]

I need to loop through all the top level contextmenustrip dropdown items.

So, I set cms.Items[0] but this gives an error with the foreach loop: "foreach cannot operate on variables of type toolstripitem".

How can I loop through just the cms.Items[0] top level (dropdown) items?

Thanks...

ContextMenuStrip cms = (ContextMenuStrip)sender;

foreach (ToolStripMenuItem item in cms.Items[0])
{
    foreach (ToolStripMenuItem dditem in item.DropDownItems)
    {
        dditem.Checked = true;
    }
{

In the foreach loop, change cms.Items[0] to cms.Items

I have that. It loops through ALL the top level cms menu items.

cms.Items[0] is the "Font Size" menu item with it's dropdown items
cms.Items[1] is the "Expander Vertical Size" menu item with it's dropdown items.

I thought there might be a way to foreach through just the cms.Items[0] part rather than loop through ALL of them.

Here is more of my menu code

            cmsListBox = new ContextMenuStrip();
            cmsListBox.Items.Clear();
            cmsListBox.Opening += new System.ComponentModel.CancelEventHandler(cmsListBox_Opening);

            listbox_font_size = new ToolStripMenuItem("Font Size");
            cmsListBox.Items.Add(listbox_font_size);
            listbox_font_size.DropDownItems.Add("8");
            listbox_font_size.DropDownItems.Add("9");
            listbox_font_size.DropDownItems.Add("10");
            listbox_font_size.DropDownItems.Add("11");
            listbox_font_size.DropDownItems.Add("12");
            listbox_font_size.DropDownItems.Add("13");
            listbox_font_size.DropDownItems.Add("14");
            listbox_font_size.DropDownItemClicked += new ToolStripItemClickedEventHandler(Listbox_Font_Size_Menu_ItemClicked);
            listbox_font_size.Name = "FontSize";

            ToolStripMenuItem listbox_expander_bar_vertical_size = new ToolStripMenuItem("Expander Vertical Size");
            cmsListBox.Items.Add(listbox_expander_bar_vertical_size);
            listbox_expander_bar_vertical_size.DropDownItems.Add("200");
            listbox_expander_bar_vertical_size.DropDownItems.Add("300");
            listbox_expander_bar_vertical_size.DropDownItems.Add("400");
            listbox_expander_bar_vertical_size.DropDownItems.Add("500");
            listbox_expander_bar_vertical_size.DropDownItems.Add("600");
            listbox_expander_bar_vertical_size.DropDownItemClicked += new ToolStripItemClickedEventHandler(Listbox_Expander_Bar_Vertical_Size_Menu_ItemClicked);
            listbox_expander_bar_vertical_size.Name = "ExpanderVerticalSize";

            listBoxTopLevelChecklist.ContextMenuStrip = cmsListBox;

foreach (var item in cms.Items[0].DropDownItems)

That gives me an error:

'System.Windows.Forms.ToolStripItem' does not contain a definition for 'DropDownItems' and no extension method 'DropDownItems' accepting a first argument of type 'System.Windows.Forms.ToolStripItem' could be found (are you missing a using directive or an assembly reference?)

Since the menu strip is a container that takes different types of items, you need to cast Items[0] to ToolStripMenuItem to access the DropDownItems list.

foreach (var item in ((ToolStripMenuItem)menuStrip1.Items[0]).DropDownItems)
{
                    
}
