Posting all selected rows using Grid.Mvc

I have successfully implemended a new Index view to my application will will render all outstanding emails to a gridview which features a checkbox for each row.

My intention now is to send an email which will include details of each record selected to a designated recipient.

Once a record has been selected and the details mailed for that record, I will flag that row as 'Emailed' and filter all emailed rows out in my controller before passing the list to the view.

I am a little confused as to how I make my submit button capture all selected records that have been checked and post the entire page back to my controller where I can do my email related stuff.

Here's what I have so far, I don't think I have wired up the submit button correctly to the gridview:

@using GridMvc.Html

@Html.Grid(Model).Columns(columns =>
           {
               columns.Add()
                .Encoded(false)
                .Sanitized(false)
                .Titled("Send Email?")
                .SetWidth(30)                
                .RenderValueAs(o => Html.CheckBox("checked", false));

               columns.Add(a => a.Id).Titled("Id").SetWidth(110);

               columns.Add(a => a.AddressLineOneOld).Titled("Old Address")
                   .RenderValueAs(a => a.AddressLineOneOld + " " +
                                  a.AddressLineTwoOld + " " + 
                                  a.AddressLineThreeOld + " " +                                  
                                  a.AddressLineFiveOld);

               columns.Add(a => a.PostcodeOld).Titled("Old Postcode").Sortable(true);

               columns.Add(a => a.AddressLineOneNew).Titled("New Address")
                   .RenderValueAs(a => a.AddressLineOneNew + " " +
                                  a.AddressLineTwoNew + " " +
                                  a.AddressLineThreeNew + " " +                                  
                                  a.AddressLineFiveNew);

               columns.Add(a => a.PostcodeNew).Titled("New Postcode").Sortable(true);
               columns.Add(a => a.Emailed).Sortable(true);

           }).WithPaging(20)

<br />

<div style="float:right;">
@using (Html.BeginForm("Index", "EmailManager", FormMethod.Post, new { name = "frm", id = "frm" }))
{
        <input id="btnSendEmailForSelected" type="submit" name="submitButton" value="Email Selected" class="btn btn-default" />
}
</div>

How do I post all selected rows back to the controller?

it this line Html.CheckBox("checked", false) add a unique name add the value for the checkbox to the Id or the unique key you have as below 

Html.CheckBox("checked", false, new {name = "selectedAddressesIds", value = "UNIQUE_KEY_HERE"})

and in the action method try the following, you must write your action method to have FormCollection

var selectedIds = form.GetValues("selectedAddressesIds");
if (selectedIds != null)
{
    foreach (var id in selectedIds)
    {
      // do what you want with the selected id.
    }
}
