About __doPostBack

[see07]

Hello:
Within JavaScript I’m using
__doPostBack(‘cmdDatosGen’, ‘ ‘);
Where cmdDatosGen is a LinkButton on side server, this code work fine executing clicks event in a web form and it is working fine.
Now instead a web form I’m using a Web User Control embedded into a web form and my script don’t work.
Is there somebody able to help me?
I’ll appreciate all suggestions.

Finally I got an answer:
__doPostBack(‘WUC11:cmdDatosGen’, ‘ ‘);
Where WUC11 is Web User Control’s name, and cmdDatosGen is Link Button’s name.
Thanks all people helped me.
