Show the code you are using; we cannot guess what is going wrong from the above.

public void SubMenu(ToolStripMenuItem menuitem, string submenu) { string get_subcatagory = "select * from medicine_subcatagory where Cat_ID=(select Cat_ID from medicine_catagory where Med_Cat='" + allopathicToolStripMenuItem.Text + "')"; DataTable dt = d.getdata(get_subcatagory); foreach (DataRow dr in dt.Rows) { ToolStripMenuItem ssmenu = new ToolStripMenuItem(dr["Med_Sub"].ToString(),null, new EventHandler(ChildClick)); if (menuitem.DropDownItems.Contains(menuitem.DropDownItems[dr["Med_Sub"].ToString()])) { menuitem.DropDownItems.Remove(ssmenu); } else { menuitem.DropDownItems.Add(ssmenu); } } } thats he code i use for add submenu in menuitem

And what happens when you step through it in your debugger? Although, at a guess it is failing the if expression. BTW please indent your code and put <pre> tags round it, so it looks like:

public void SubMenu(ToolStripMenuItem menuitem, string submenu)
{
string get_subcatagory = "select * from medicine_subcatagory where Cat_ID=(select Cat_ID from medicine_catagory where Med_Cat='" + allopathicToolStripMenuItem.Text + "')";
DataTable dt = d.getdata(get_subcatagory);

foreach (DataRow dr in dt.Rows)
{
    ToolStripMenuItem ssmenu = new ToolStripMenuItem(dr\["Med\_Sub"\].ToString(),null, new EventHandler(ChildClick));
    if (menuitem.DropDownItems.Contains(menuitem.DropDownItems\[dr\["Med\_Sub"\].ToString()\]))
    {
        menuitem.DropDownItems.Remove(ssmenu);
    }
    else
    {
        menuitem.DropDownItems.Add(ssmenu);
    }
}

}

A quick glance at the documentation[^] suggests that you are testing against the wrong object type.
