Having trouble injecting Javascript in AJAX enabled page withRegisterClientScriptBlock

[CrystalMikeMD@gmail.com]

Greetings,

I've been at this problem for some time now and have decided to seek
out some help.

Essentially, this is what I have. A basic ASP.NET 2.0 page. On this
page is the standard <formtag. Under that, we have an UpdatePanel
object where the rest of my partial rendering controls live. There is
simply a basic control, such as a Literal or Label in the
UpdatePanel. When a button is clicked on the page, I want to send out
Javascript back to the Label or Literal (set the Text property of this
control with javascript) such as "<script>alert( 'hello');</script>"

The problem? Whatever I send to the control gets there but nothing is
ever executed.

So, I have started trying RegisterClientS criptBlock() on the top level
"Page" object and even at the inner control level.

Nothing seems to happen.

If I inject javascript in the "Page_Load" method, it runs and works.
However, I need to inject javascript at a later time after the page
loads (since this is AJAX).

Does anyone have any words of advice? Anyone that has been down this
road? I sure would appreciate some help.

I got it.

Use the STATIC method "RegisterClient ScriptBlock" instead of the
ClientScriptMan ager for a control.

Something like this will work globally:

Microsoft.Web.U I.ScriptManager .RegisterClient ScriptBlock(Upd atePanel1,
typeof(UpdatePa nel),“TestKey”, “alert(’Test’); “, true);

Two days wasted but now I feel better.

Re: Having trouble injecting Javascript in AJAX enabled page withRegisterCli entScriptBlock

you server injected client to be render from a update panel postback,
you code needs to call the ScripManager.Re gisterClientScr iptBlock and
this call must be from a control inside the update panel. this is
because only html/script rendered inside the update panel is returned to
the client.
