Answer 1

Try like this:

OnClientClick='<%# string.Format("setSessionValue(\"video\", {0});", Eval("movieTitle")) %>'

Or even better ensure that you properly encode the movie title using the JavaScriptSerializer class:

OnClientClick='<%# string.Format("setSessionValue(\"video\", {0});", new JavaScriptSerializer().Serialize(Eval("movieTitle"))) %>'

Yeah, I agree, what a horrible mess are those WebForms. You would probably externalize this into a function in your code behind:

public string FormatJs(object movieTitle)
{
    return string.Format(
        "setSessionValue(\"video\", {0});", 
        new JavaScriptSerializer().Serialize(movieTitle)
    );
}

and then:

OnClientClick='<%# FormatJs(Eval("movieTitle")) %>'
