protected virtual bool DetermineRenderUplevel ()
protected boolean DetermineRenderUplevel ()
protected function DetermineRenderUplevel () : boolean

Return Value

true if the validation control can be rendered for a newer browser; otherwise, false.

The DetermineRenderUplevel method is a helper function used primarily by the RenderUplevel property to determine whether the client's browser supports "uplevel" rendering. For a browser to support "uplevel" rendering, it must support Microsoft Internet Explorer Document Object Model (DOM) version 4 or later and ECMAScript version 1.2 or later.


This method is used primarily by control developers.
