Hello all,

I've got a form where users can edit members of a group.

So they have the possibilty to add members or remove existing members. So the Url goes like ".../Group/Edit/4" Where 4 is the id of the group.

the view looks like this

<% using (Html.BeginForm("AddUser", "Group")) %>
    <%{%>
        <label for="newUser">User</label>
        <%=Html.TextBox("username")%>
        <input type="submit" value="Add"/>
    </div>
    <%}%>

    <% using (Html.BeginForm("RemoveUser", "Group")) %>
    <%{%>
    <div class="inputItem">
        <label for="groupMember">Bestehende Mitglieder</label>
        <%= Html.ListBox("groupMember", from g in Model.GetMembers() select new SelectListItem(){Text = g}) %>
        <input type="submit" value="Remove" />
    </div>
    <%}%>

The problem is that after adding or removing one user i lose the id of the group. What is the best solution for solving this kind of problem? Should I use hidden fields to save the group id?

Thanks in advance.
