C# web browser select list item click

Question

I am trying to select item from select list box using this method:

 var elements = webBrowser1.Document.GetElementsByTagName("select"); foreach (HtmlElement element in elements) { if (element.GetAttribute("id")=="pagesize") { element.GetElementsByTagName("option")[2].SetAttribute("selected", "selected"); webBrowser1.Document.InvokeMember("click"); } }

from this html code

<select name="pagesize" id="pagesize" onchange="changeFileListRequestSize();"> <option value="10">10 files per page</option> <option value="25" selected="selected">25 files per page</option> <option value="50">50 files per page</option> <option value="100">100 files per page</option> <option value="200">200 files per page</option> </select>

item is actually changes but that's doesn't execute onchange="changeFileListRequestSize();" javascript event.

how to simulate select list item click or "change"
