Update of /cvsroot/magicajax/magicajax/Core/UI
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20348/magicajax/Core/UI
Modified Files:
RenderedByScriptControl.cs
Log Message:
Firefox keeps the form data of a page when doing a page reload or using
the back/forward button.
However, the 'RenderedByScriptControls' will disappear after a reload.
To redraw these controls on the page, we will force a callback from the client's
window.onload when the value of hidden field '__RBSCONTROLSEXIST'
equals '1'. This hidden field is set to '1' whenever a callback is made.
On first page rendering, the value of this hidden field is '0'.
Internet Explorer always resets all form data on a page refresh (also the hidden
field '__RBSCONTROLSEXIST'), so for IE no extra callback will be forced.
