Datagrig window.open registerstartupscript problem

Hi All. I have just finished a contract and returned to a project I was working on. Something very odd has happened while I was away. I have a DataGrid which dispayes a set of results from our DB. The datagrid has a button called "Play". When "Play" is clicked, it should bring up a poup window displaying a "Music Player". This code below worked 3 weeks ago but is not working now. I already tried RegisterClientScriptBlock. Any bright ideas on what is happening? In advance, many thanks for all your help.

This is a stripped down version of the code:

VB.NET
####################
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim dt As New DataTable
Dim i As Integer
Dim dr As DataRow
dt.Columns.Add("SomeCol", System.Type.GetType("System.String"))
For i = 1 To 4
dr = dt.NewRow()
dr("SomeCol") = i.ToString
dt.Rows.Add(dr)
Next
DataGrid1.DataSource = dt
DataGrid1.DataBind()
End Sub

Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.ItemCommand
If e.CommandName = "Play" Then
Dim popupScript As String = "<script language='javascript'>" & _
"window.open('../player/right_frame.aspx', 'Window', 'width=200, height=200');" & _
"</script>"

Page.RegisterStartupScript("playerPopup", popupScript)

End If
End Sub

hi YZlat. thanks. each of the "Play" buttons is dynamic and carries a queryString with it i.e page.aspx?userID=XXXtrackID=XXX..... so it not a question of just one button. there are quite a few of them. these are generated by the fields in the datagrid i.e datagrid1.items(x).Cells(x) and repeats itself for all the retuned entries. i am not sure if btnPlay.Attributes.Add can be made dynamic in this case? any thoughts?

Phillie the code above will produce as many buttons as there are rows in the datagrid. You could also change it to a link ro a linkbutton and pass it a unique query string
