Can one cause Page.IsPostBack to be true independently of ASP.net?

by

If one is checking a user’s roles to determine whether they may access a page, is it safe to put this check only inside an if (!Page.IsPostBack) { ... }? Could it be possible for the client to cause Page.IsPostBack == true independently of ASP.net; that is, the client POST’s to the page and sets the right form fields? If that were possible, then I suppose best practice would be to check security on every page load, not just when Page.IsPostBack == false.

AppSettings in App or Web Config Using a Linked File

The file (named common.config) that is being referenced is a linked file in a separate project in the same solution. That common.config is set to Content with Copy Always in both projects.

Is there a way to insert Silverlight XAML into my page using ASP.NET code-behind?

by

So, I want to create some Silverlight charts from some data on my ASP.NET web page. The way to do this, either using Visifire (my current thing) or the upcoming Silverlight charting, seems to be to create some XAML, or at least some Silverlight objects (like in this Visifire sample), and then stuff them into the page somehow.
