i currently have:
String url = "../CustomerSettings/CustomerConfiguration.aspx?CustomerID=" + sqlCommand.Parameters["@ReturnCustomerID"].Value.ToString();
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "myUniqueKey", "self.parent.location='"+url+"';", true);
this works great to redirect the parent page but I need it to open a new tab. Any suggestions?
