attributes - style tag automatically added to ASP.NET ListBox control -


i have asp.net project following line of code:

<asp:listbox id="lbxinvoices" runat="server" selectionmode="multiple" rows="16"></asp:listbox>

obviously, i'd control render 16 rows. unfortunately, refuses so...when check html source page, see following:

<select size="16" name="ctl00$cphmaincontent$wizard1$lbxinvoices" multiple="multiple" id="ctl00_cphmaincontent_wizard1_lbxinvoices" class="defaultlistbox" style="height:100px;width:250px;">

where did class attribute come from? , more importantly, did style attribute (which apparently overriding "size" attribute) come from? how can rid of them?

if add style="height: auto" attribute server side tag, can work, seems weird, , i'd stop adding attribute in first place.

am missing something?

( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
