Answer 1

The method System.Web.UI.Page.RegisterClientScriptBlock has been deprecated for some time (along with the other Page.Register* methods), ever since .NET 2.0 as shown by MSDN.

Instead use the .NET 2.0 Page.ClientScript.Register* methods. - (The ClientScript property expresses an instance of the ClientScriptManager class )

Guessing the problem

If you are saying your JavaScript alert box occurs before the page's content is visibly rendered, and therefore the page remains white (or still unrendered) when the alert box is dismissed by the user, then try using the Page.ClientScript.RegisterStartupScript(..) method instead because it runs the given client-side code when the page finishes loading - and its arguments are similar to what you're using already.

Also check for general JavaScript errors in the page - this is often seen by an error icon in the browser's status bar. Sometimes a JavaScript error will hold up or disturb unrelated elements on the page.
