Hi Nithya. G,

I use EssentialObject menu control to create dynamic menu.

Sub CreateMenu()
        Dim MI As EO.Web.MenuItem
        Dim MII As EO.Web.MenuItem
        Dim MIII As EO.Web.MenuItem
        Dim Add As Boolean

        MyMenu.Items.Clear()
        MyMenu.EnableScrolling = True
        MyMenu.EnableViewState = False 
        MyMenu.ScrollDownLookID = "scroll_down"
        MyMenu.ScrollUpLookID = "scroll_up"
        MyMenu.ScrollSpeed = 100 

        Dim SQL As String
        Dim I As SByte = 0

        Dim CnMenu As New SqlClient.SqlConnection
        Dim CnSubMenu As New SqlClient.SqlConnection
        Dim CnFunction As New SqlClient.SqlConnection

        SQL = "Select MasterMainMenu.MainMenuID, MasterMainMenu.MainMenuName, MainMenuLink from MasterMainMenu order by Seq "
        GetCN(CnMenu)

        Dim CmMenu As New SqlClient.SqlCommand(SQL, CnMenu)
        Dim RdMenu As SqlClient.SqlDataReader
        RdMenu = CmMenu.ExecuteReader()
        Do While RdMenu.Read
            MI = New EO.Web.MenuItem
            MI.ItemID = RdMenu.Item("MainMenuID").ToString.Trim
            MI.Text.Html = RdMenu.Item("MainMenuName").ToString.Trim
            If RdMenu.Item("MainMenuLink").ToString.Trim <> "" Then MI.NavigateUrl = RdMenu.Item("MainMenuLink").ToString.Trim

            MI.HoverStyle.Font.Size = 8
            MI.HoverStyle.Font.Bold = True
            MI.NormalStyle.Font.Bold = True
            MI.NormalStyle.Font.Size = 8
            MI.HoverStyle.ForeColor = Drawing.Color.RoyalBlue
            MyMenu.Items.Add(MI)

            SQL = "Select FunctionID, SubMainMenuName, SubMainMenuID, FunctionLink from MasterSubMainMenu where MainMenuID='" & RdMenu.Item("MainMenuID").ToString.Trim & "' Order By Seq"

                MII.HoverStyle.ForeColor = Drawing.Color.Red
             
                MII.HoverStyle.Font.Size = 8
