I am new to ASP.net and DNN module development.  I have creating a working module, and would like to inject javascript into the page via the server-side code-behind event handler for a Button.  I am successfully injecting javascript in the Page_Load event using RegisterClientScript, but when I try the same technique in a Button event handler, I can see using the brower's view-source that the javascript is not being written to the page.

I don't know if this is an ASP.Net page build life-cycle issue, or a DNN-specific issue.  Can anyone point me in the right direction?

Thanks for your reply.  The specific reason for my question is that I have a tall input form and In a button postback event handler I am doing server-side validation, and then displaying error messages using DotNetNuke.UI.Skins.Skin.AddModuleMessage().  In Firefox, Opera, Chrome, & Safari the returned page is scrolled to the top so that the AddModuleMessage display is visible without scrolling - even when scrolled to the bottom of my tall form when the button is clicked.  In IE however, if I click the button while scrolled to the bottom of the form, the  DNNModuleMessage at the top is not in view, so it would be easy to miss the error message display.  I had hoped to insert some javascript in the button event handler to cause the page to scroll to the top so the AddModuleMessage display would be visible.
