Need help on query string in asp.net

Question

I have a create-quote.aspx page. I want to open this page in different modes, depending on whether the querystring parameter is present or not.

My question is which event should be checked if I have a querystring parameter or not. I think it should be despised what you say.

Answer 1

Probably the best choice is to handle them on the Page_Load event:

Answer 2

You're right. You must check the request in the preinit event. Before initialization, the start phase begins, where request request objects are created.

Answer 3

I would check that there is something like this in the Page_Load event:

Page_Load { if(!Page.IsPostback) { if(Request.QueryString["id"] != null) { // do whatever with the id value } } }
