Telerik's Controls

[George Ter-Saakov]

I saw the thread here about Telerik's controls and to tell the truth I like
them.....thinking about purchasing myself.

so decided to ask a question.

How heavy are they?
In terms of JavaScript and in terms of ViewState...
I understand there are bunch of controls there and they have different
footprint... But I mean just on average....

I hope they do not add 500K Javascript library......


Thanks
George.

The latest version of the RadControls compiles all the separate controls
into one dll file so that really does help performance as it reduces the
number of calls between dlls. They have also introduced a couple of
wonderful features to help combine scripts used by the various controls on a
page into one file (making them much lighter and far less repetetive) as
well as combining css stylesheets for the various controls used in a page.

A few good performance articles from Todd Anglin, a Telerik employee and
their best evangelist are:

Ajax manager optimization

general manager optimization
http://telerikwatch.com/2008/04/optimization-tipsthe-rad-managers-for.html

Their documentation for the RadScriptManager is at:
http://www.telerik.com/help/radcontrols/prometheus/?RadScriptManager.html
and for the RadStyleSheetManager is at:

The managers really do help in trimming the page down as well as caching the
data for better performance on subsequent hits.

Hope this helps,
