Hi all

Please check my code

C#

MainMenu first_menu = new MainMenu();
this.Menu = first_menu;

MenuItem[] secondMenu = new MenuItem[2];
MenuItem menu = new MenuItem(row["CategoryId"].ToString());
secondMenu[0] = menu;

MenuItem Parent_menu = new MenuItem( row["Name_tb"].ToString(), secondMenu);

error happening as object reference does not set to an instance of object

What may be the reason,how to pass value field of menu item in windows application other than this method

Thanks in Advance

hi
this line is throwing exception
MenuItem Parent_menu = new MenuItem( row["Name_tb"].ToString(), secondMenu);

So, either row["Name_tb"] is null or secondMenu is null. Just use the debugger.

something is null - I'd guess your row-Value is null or empty. check with the debuger, or give full exception text here - (look at the stack trace which line causes the error) You can also split your code and use some "intermediate" variables (e.g. string strID = row["CategoryId"].ToString();) for debugging so you can find out which statement causes the exception
