Answer 1

Use ClientScript class instead of ScriptManager

private string test()
{
   if(somecondition)
   {
       ClientScript.RegisterStartupScript(Page.GetType(), "HideSlider1", "HideSlider();", true);
   }
   return stringvalue;
}

Answer 2

Try this.

private string test()
{
    if(somecondition)
    {
         ScriptManager.RegisterClientScriptBlock(Page, GetType(), "HideSlider1", "<script type='text/javascript'>HideSlider();</script>", true);
    }
    return stringvalue;
}
