Dynacly add scriptmanager when needed?

Hi,

I'm trying to create a Web User Control that uses asp.net Ajax. I'd like it to find out if a scriptmanager already exists in the page and, if not, add ti dynamically. Would such a thing be possible?

Thanks in advance for any help.

Regards,

Stefan

Yes its possible, you can check if ScriptManager is registered. FindControl(); or you can added it in the Master Page

Thanks for your quick reply. But how would I use FindControl if I don't know what the name of the scriptmanager would be?

I'm thinking of a situation where my control gets used in combination with other ajax controls, or gets used multpile times on a form. (Actually, my control would be a DotNetNuke module)

Any ideas?

If you didn't change it ScriptManager1

I know, but the hard thing is, that all controls get added to the page dynamically by DotNetNuke. This means I'm pretty sure the name won't be ScriptManager1...

So if there's no other way than to use findcontrol, the only option would be to add the ScripManager to the page itself somehow.

Thanks for your help.

hello.

you can get a reference to the ScriptManager control by using the static GetCurret method. If there's already a ScriptManager on the page, you will get a non null value.

I've put together an example ofUsing Control Adapters to automatically attach AJAX Extenders to ASP.NET Controls, which isn't exactly what you want, but there is code for walking through the controls on a page to see if there is already a ScriptManager or ScriptManagerProxy ...

hello.

hum...why are you going through a cicle to get the scriptmanager control?

Because I'm doing it from an HttpModule ... and also because I didn't know of the static method :-)

Not sure if it will work in the module though ... will have a go.

hello.

well, i guess it might not work if you haven't instantiated the master page (which is easily solved by just "touching" the property)

Hi again, it's been a while since I had time to figure this thing out, but your answers look promising. Thanks a lot so far.
