It's possible, but you're going to need to provide a little bit more information for a specific answer. Your framework/architecture play a role (potentially) in how this performs. Also, whatever else happens on your rowclick event make a difference on what you can/should do. There are large handful of methods to accomplish what you want. A few things to remember though:
1. Consider partial vs. full post back on your .NET control and how that will affect your JavaScript. In other words, look into what happens to your JavaScript on a full post back (when the page essentially refreshes for lack of better words).
2. Re: #1, Hint: You want a partial post back. You're also going to want to look at how to register client scripts in your .NET code. Registering client scripts is a way to make sure your JavaScript functionality occurs after an event fired by a .NET server control.
3. Consider not using a .NET server control and look into other avenues to display your data. Look at maybe parsing your .NET data into JSON and using a client friendly control to display your data and use an input button element for your zoomTo.
