asp.net mvc - cannot use Html helper in partial view? -

background

i have following method in controller

[httpget]  public actionresult getmodulepropertyname(string moduletypevalue)  {     var modulekindid = _repository.getmodulekindid(moduletypevalue);     var modulepropertynames = _repository.getmodulekindpropertynames(modulekindid);     return partialview(modulepropertynames);   } 

modulepropertynames may contain list of strings of null.

what want do

i want create text box each string passed partial view placeholder or label string, user type text there later retrieve.

what i've been doing

i'm doing following right now, says cannot resolve symbol textboxfor

@foreach (var names in model) {   <div class="input-block-level">@html.textboxfor(names, new {@placeholder = names})</div> }

html.textboxfor taking expression<func<list<model>>, tproperty> first argument. try use way:

@for (int = 0; < model.count; i++) {     @html.textboxfor(name => name[i], new {@placeholder = names}) } 

or use html.textbox():

@for (int = 0; < model.count; i++) {     @html.textbox("name[" + + "]", model[i], new {@placeholder = names}) }
