Answer 1

Create two hidden fields, one with name StartDate and other with name EndDate and assign the values accordingly. These values will be available in the controller when you post the form.

<input type="hidden" name="StartDate" value="@Model.StartDate" />
<input type="hidden" name="EndDate" value="@Model.EndDate" />
