] | I am trying to RegisterClientScriptBlock in a method that is only called via an AJAX call. It doesn't appear to actually register the script on the page and I'm guessing this is because it's not actually reloading the entire page. Is there any way to register javascript on a page from within an ajax method call?
```
... | With AJAX enabled pages, you should use the ScriptManager to register scripts:
```
ScriptManager.RegisterClientScriptBlock(Page, typeof(MyPage),
"MyScript", "GoStuff()", true)
```
You can use this to register all your scripts (Original load, postback, AJAX postback). |
