First of all, in order to get values from dynamically generated controls you can either follow the steps I'll discuss after this, or use Request.QueryString for GET requests, Request.Forms for POST requests, or Request.Params if you don't care which HTTP method the parameters come through. Since each is a collection, you can either enumerate all the values and sort out what is what using the names and values, or access the values using the name (like Request.Params["Month1"]).

Second, in order to keep the controls on the page, you must make sure that in Page_Load you are not clearing the controls or re-binding them when you don't want to by using the IsPostBack property. On the first request to the page, this property is false so bind any data / generate controls. If a user submits the page form, this property is true so skip all that stuff, but only if you've set EnableViewState for the page and other controls to true (which is the default).

For more information, see Page.EnableViewState Property[^] (includes example), Page.IsPostBack Property[^] (includes example), and a nice little article that should help tie them all together, Taking a Bite out of ASP.NET ViewState[^].
