Calling a Javascript function from C# class

For some reason I can't figure out what I'm doing wrong on this - despite several things I've found on the internet.

I'm trying to adjust the size of the page based on information selected prior to the page load or upon a selected change in a dropdown. I have the controls in cells and rows in a table.

This is part of the aspx code:

Then in the .cs file, I've tried:

1. adding this - protected System.Web.UI.WebControls.Literal useJS;

then in the Page_Load and SelectedIndexChange methods, I've put:
.....
useJS.Text="";
--this errors when hit

2. Just adding in the Page_Load and SelectedIndexChange methods:
Javascript:rowTestHide();
--this errors when hit

3. Or I tried this:
String scriptString = "";
Response.Write(scriptString);

--this also errors when I try it

As you can probably see, I don't know what I'm doing. This seems that it would be siimple enough, but I haven't figured it out.

Thanks for your help.

A little more searching and this is all I had to put in my C# code in the event I wanted it to fire from:

string rowTestHide = "";
RegisterStartupScript("rowTest",rowTestHide );

It works. I'm not certain this is the most efficient way, but it's a very small application, only accessed through our intranet, so I'm not concerned about a performance hit.

Thanks.
