I have a linkbutton on a form that executes a script, it works fine except
that it posts back to the calling form first. Is there a way to prevent
this? I tried setting the PostBackURL property to the form the script
launches but that resulted in some strange behavior.

TIA
 
Hi Eric,

E.g. you can use this linkbutton .Attributes.Add("onclick", "return false")
if you just need to run script in OnClientClick and prevent postback.

a LinkButton is an anchor with javascript added to do a postback. if you
don't want to do a postback, don't use a link button, just use an anchor (or
HyperLink). if you just want to call a javascript routine from an anchor, the
usual trick is:

<a href="#" onclick="myfunction(this);return false;" >Click me</a>
or
<a href="javascript:myfunction(this);" >Click me</a>

note: some installs of IE fail to honor return false from an event, and must
include code to cancel event bubbling.
