Is User Control in Asp.Net can be completely self contain? -


i trying make usercontrol have data process, initialize data, ajax, self contain 1 control. can insert anywhere on asp pages.

but problem is, usercontrol contains script manager , page contain user control has script manager too, asp doesn't allow me have 2 script manager in 1 page.

in case this, wonder if usercontrol can self contain? or proper way of using usercontrol using template, , data process, event handler have on page contains usercontrol?

thanks.

======edit: guess use scriptmanager.getcurrent check if page exists scriptmanager , add otherwise. thanks.

for part, can make self-contained. use clientscript object. this:

if (!page.clientscript.isclientscriptblockregistered("key")) {     page.clientscript.registerclientscriptblock(gettype(), "key",         "function myfunction() {" +         "..." +         "}", true); }

by providing unique key code block, can ensure particular block of javascript added page once, , once.
