the error in: @html.editorfor(item.checkbox1)

i tried change @html.textbox(item.checkbox1) or @html.checkboxfor(item.checkbox1) , error remain,any idea how manage it?

instead of using loop try foreach , display each items.

for eg :

@foreach (var item in model)  {   <tr>    <td>      @html.textbox(item.name)    </td>   </tr> } 

edit

@foreach (var item in model)         {             <tr>                 @if (item.id == viewbag.selectedid)                 {                     <td>                         @html.textbox(item.name)                     </td>                     <td>                         @html.checkbox(item.checkbox1)                     </td>                       <td>                         <button type="submit" name="submit" value="save">save</button>                         <button type="submit" name="submit" value="cancel">cancel</button>                     </td>                 }
