JavaScript - Open a new window with parameters

I have to open a new window from my ASP.net web application.

Here is the code I've been using.

Dim strScript As String = "<script language='javascript'>" & vbCrLf
strScript += " function window.onload() {" & vbCrLf
strScript += "    window.open('POREP01.aspx'); }" & vbCrLf
strScript += "</script>" & vbCrLf

Me.RegisterClientScriptBlock("strScript", strScript)

This works fine. But now I hwve to do the same thing on another page with parameters...and I am not able to place the parameters in Javascript, being new to JavaScript. Here is an example of a page which I have to open in a new window.

OrderpreviewPO.aspx?ordernumber=" & Me.ddlOrderNumber.SelectedItem.Value

Priya25,
Try this :

        Dim ParentLoadScript As String
        Dim strURL As String

        If IsPostBack Then
            strURL = "POREP01.aspx?ordernumber=" + Me.ddlOrderNumber.SelectedValue.ToString
            ParentLoadScript = "<script language=javascript>"
            ParentLoadScript &= "window.open('" + strURL + "');"
            ParentLoadScript &= "</" & "script>"
        End If

        If Not IsClientScriptBlockRegistered("ParentLoad") Then
            RegisterClientScriptBlock("ParentLoad", ParentLoadScript)
        End If
