Try this:
Adding Parent Menu Items:

C#

private void AddTopMenuItems(DataTable menuData)
{
      DataView view = null;
      try
      {
          view = new DataView(menuData);
          view.RowFilter = "ParentID IS NULL";
          foreach (DataRowView row in view)
          {
               //Adding the menu item
               MenuItem newMenuItem = new MenuItem(row["Text"].ToString(), row["MenuID"].ToString());
               menuBar.Items.Add(newMenuItem);
               //Calling the function to add the child menu items
               AddChildMenuItems(menuData, newMenuItem); //This function will add child menu items to your menu control.
          }
      }
      catch (Exception ex)
      {
          //Show the error massage here
      }
      finally {
            view = null;
      }
}

Adding Child Menu Items:

C#

private void AddChildMenuItems(DataTable menuData, MenuItem parentMenuItem)
{
    DataView view = null;
    try
    {
        view = new DataView(menuData);
        view.RowFilter = "ParentID=" + parentMenuItem.Value;
        foreach (DataRowView row in view)
        {
            MenuItem newMenuItem = new MenuItem(row["Text"].ToString(), row["MenuID"].ToString());
            newMenuItem.NavigateUrl = row["NavigateUrl"].ToString();
            parentMenuItem.ChildItems.Add(newMenuItem);
            // This code is used to recursively add child menu items filtering by ParentID
            AddChildMenuItems(menuData, newMenuItem);
        }
    }
    catch (Exception ex)
    {
        //Show the error massage here
    }
    finally
    {
        view = null;
    }
}
