ScriptManager::OnPreRender Method (EventArgs^)
Raises the PreRender event, and registers script files and services for partial-page updates.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The browser that made the partial-page request does not support at least DOM Level 1.0.
For information about the DOM, see the Document Object Model (DOM) Level 1 Specification on the World Wide Web Consortium (W3C) Web site.
Notes to Inheritors:
When overriding this method, call the basemethod so that script blocks and services are correctly handled for partial-page rendering.
