ASP.NET Response.Redirect to new window

Hi All,
 
I have an query when user select any option it should redirect and open new tab in same browser, actually it worked fine in firefox and IE but in chrome it opens a new window. Below is the code. Could anybody help me.
 
Protected Sub cboSports_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboSports.SelectedIndexChanged If cboSports.SelectedValue <> "" Then Response.Write("<script>") Response.Write("window.open('" & cboSports.SelectedValue & "','_blank')") Response.Write("</script>") End If End Sub
 
Thanks in Advance
