Comment from OP:
Sorry But I had already seen that code , Problem is what ,

In your suggested code menu is also creating dynamaticaly but in My code I used Menu in design time then added its item at run time on Code behind according to above method..but Menu what I created on design time has Value nothing means null thats why its showing exception of Object reference not found...

Hi
If you are using master page then you have to access it from the master page as below

C#

if (!IsPostBack)
{
    MenuItem mItem1 = new MenuItem();
    mItem1.Text = "Test Menu";
    Menu menu = (Menu)this.Master.FindControl("NavigationMenu");
    menu.Items.Add(mItem1);
}

I think vb.net it may be like Dim menu as Menu= Me.Master.FindControl("StepPlanMenu1")
