Changing Param programaticly

Apr 17, 2009 at 10:54 PM
Id like to be able to change the value of a param via event (button click)
<param name="initParams" value="xmlDataPath=gallery4.xml" />

I'm sure this is simple ASP.NET Dev 101 stuff but I keep finding myself going in circles with the documentation.
Anybody mind throwing me a bone?
