ASP.net MVC 2.0 using the same form for adding and editing

Question

I would like to use the same view to edit a blog post and add a blog post. However, I have a problem with the ID. When adding a blog post, I don’t need to post an id value. When binding to a model binds the form values ​​to an object BlogPostin the controller, it will automatically generate an identifier in the entity of the entity frame.

When I edit a blog post, I need a hidden form field to store the identifier so that it accompanies the next form post. Here is the view I have right now.

<% using (Html.BeginForm("CommitEditBlogPost", "Admin"))
       { %>
            <% if (Model != null)
               { %>
                    <%: Html.HiddenFor(x => x.Id)%>
            <% } %>
            Title:<br />
            <%: Html.TextBoxFor(x => x.Title, new { Style = "Width: 90%;" })%>
            <br />
            <br />
            Summary:<br />
            <%: Html.TextAreaFor(x => x.Summary, new { Style = "Width: 90%; Height: 50px;" }) %>
            <br />
            <br />
            Body:<br />
            <%: Html.TextAreaFor(x => x.Body, new { Style = "Height: 250px; Width: 90%;" })%>
            <br />
            <br />
            <input type="submit" value="Submit" />
    <% } %>
