Page.RegisterClientScriptBlock() is not working ..... :-(

[Vipul Pathak]

Hi,

I am writing a WebControl. With that I need to emit JavaScript code on the
page. For that I am using "Page.RegisterClientScriptBlock" method inside the
PreRender event. It is shocking to see that the the method takes the script
to emit, but does not actually emit it on the page. Neither it throws any
exception.

I am emiting JavaScript from 2 places: PreRender event and Render event. In
PreRender, I am using Page.RegisterClientScriptBlock() and In Render I am
using output.Write(). It could be noticed that output.Write() is working,
but Page.RegisterClientScriptBlock() is not.

What might be the reason? Any Help ?

Thanks,

PS: Also to note, RegisterStartupScript() is working from PreRender.

Did you look at the HTML source of the rendered page to make sure it's not
being emitted? Did you wrap your javascript with <script language=javascript></script>?
PreRender should be fine for doing this.

Yes, I have done all that ...

I'd suggest building the smallest app you can where this doesn't work. When
I build a page that does as you suggest it works fine (RegisterClientScriptBlock
in PreRender).

Yes, we had this before. The reason is, I believe, you are registering the
script too late. Try registering the script before PreRender is called...in
a different event or method?
