public class checkbox

{

int id;

string name;

bool selected;

}

and I call this in viewmodel as List<checkbox> list

when I am binding the list into view is successfully but when I am getting the selected values the model data shows list: count=0 when selected otherwise shows null

@foreact(var item in model.list){

<input type="checkbox" @selected name="list" value="@item.id">

}

how can I get these values from view to controller

this is not good

name="list"

Hi Siva,

assign a name to your checkbox:

<input name="gender" type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />

Then in your action do something like below:

[HttpPost]
        public ActionResult HandleFormSubmit(string[] gender,
             MembershipFormViewModel model)
        {
            //model not valid, do not save, but return current umbraco page
            if (ModelState.IsValid == false)
            {
                return CurrentUmbracoPage();
            }
            string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here
            return RedirectToCurrentUmbracoPage();
        }

you need to understand how checkboxes post their data. if they have a name attribute, when checked, they post name=value, else if not checked its value is not included in the postback data. so if you had three checkboxes

   <input type="checkbox" name="list" value="1" checked>
   <input type="checkbox" name="list" value="2" >
   <input type="checkbox" name="list" value="3" checked>

and the user did not change the check, the postback data would include:

   list=1&list=2

the mvc binder can bind this data to a string array or numeric array. but that is not what you have. if you change the checkboxes to:

  <input type="checkbox" name="list.id" value="1" checked>
   <input type="checkbox" name="list.id" value="2" >
   <input type="checkbox" name="list.id" value="3" checked>

the binder could blind it your list, but it would only contain 2 entries, and only the id would be filled in. to get you complete list posted back it would be:

@for(var i=0; i < model.list.Count; ++i){
   @Html.HiddenFor(m=>m.list[i].id)
   @Html.HiddenFor(m=>m.list[i].name)
   @Html.CheckboxFor(m=>m.list[i].selected)
}

if you wanted to manually handle the  checkbox its:

    <input type="checkbox" @(Model.list[i].selected ? "checked" : "") name="list[@(i)]" value="true">
