I want to change on mouse over to onclick event. so when use click on parent item, it should open subitem and on next click it should close the menu.

Ok i got it now.

Do following :

Create one class derived from menu control.

Override render event

C#

Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)

            Dim stringBuilder As StringBuilder = New StringBuilder()
            Dim stringWriter As StringWriter = New StringWriter(stringBuilder)

            Dim htmlWriter As HtmlTextWriter = New HtmlTextWriter(stringWriter)
            MyBase.Render(htmlWriter)

            Dim html As String = stringBuilder.ToString()

            Dim strMouseHover = "onmouseover=""Menu_HoverStatic(this)"""
            Dim strMouseClick = "onclick=""Menu_HoverStatic(this)"""

            Dim str As Boolean = html.Contains(strMouseHover)


            html = html.Replace(strMouseHover, strMouseClick)

            writer.Write(html)

        End Sub

Then overide Menu_HoverStatis(this) function as per below link:
