view:

@html.radiobuttonfor(model => model[i].issufficient, beoordeling.voldoende, new { @checked = "checked", id = "voldoende" + })                         @html.label("voldoende" + i, "voldoende")                         @html.radiobuttonfor(model => model[i].issufficient, beoordeling.onvoldoende, new { id = "onvoldoende" + i})                         @html.label("onvoldoende" + i, "onvoldoende") 

output html:

<input checked="checked" data-val="true" data-val-required="het veld issufficient vereist." id="voldoende0" name="[0].issufficient" type="radio" value="voldoende" /> <label for="voldoende0">voldoende</label> <input id="onvoldoende0" name="[0].issufficient" type="radio" value="onvoldoende" /> <label for="onvoldoende0">onvoldoende</label> 

as can see in comment in controller, issufficient have value 'beoordeling.voldoende'. can me?

i have found solution. instead of radionbuttonfor(issufficient) use result. don't if solution, works!
