Dear Friend,

can you please help me to give me any idea about how I can create a DB driven TREE MENU and which will call FORM.

I have create a TREE MENU but that is hard coded not DB driven and I have introduce some click evens for every MENU to call FORM.

But I need to know how I can create a TREE MENU Dynamically and what is the technique to handle CLICK EVENT to call any FORM which also dynamically.

Please help me to give me some IDEA.
