Answer 1

If you are binding your checkboxes to a Dictionary try this:

<% var i = 0; %>
<% foreach (KeyValuePair categoryCheckbox in Model.CategoryCheckboxes) {%>

    " value="<%= categoryCheckbox.Key %>" />
    <%= Html.CheckBox(String.Format("CategoryCheckboxes[{0}].Value", i), categoryCheckbox.Value) %>

    <%= categoryCheckbox.Key %>

    <% i++; %>
<% } %>

Hope this helps

UPDATED:

For binding to IDictionary your form must contain inputs with "CategoryCheckboxes[n].Key" and "CategoryCheckboxes[n].Value" Ids/Names, where n must be zero-based and unbroken.
