string item1="category1"; string Script = "window.program = '" + item1 + "';"; Page.RegisterStartupScript("PopupScript", Script);

item1 gets generated dynamically from some value in code behind. But its not working. Any suggestoins where I m getting wrong?

You need it wrapped in script tags, there's an overload for this in the newer replacement ClientScript:

string item1="category1";
string Script = "window.program = '" + item1 + "';";
Page.ClientScript.RegisterStartupScript(GetType(), "PopupScript", Script, true);

Unless you're on .Net 1.1 I believe, Page.RegisterStartupScript is deprecated.
