ASP:UpdatePanel + Triggers virker ikke

Jeg har følgende kode:
<strong>Publish to my network(s):</strong><br />
        <asp:RadioButton ID="CreateSwapNetworkCustom" runat="server" ValidationGroup="ValidationGRPCreateSwap"
            GroupName="CreateSwapNetworkRadio" Text="Custom" OnCheckedChanged="CreateSwapNetworkCustom_CheckedChanged"
            AutoPostBack="true" />
        <asp:RadioButton ID="CreateSwapNetworkAll" runat="server" ValidationGroup="ValidationGRPCreateSwap"
            GroupName="CreateSwapNetworkRadio" Text="All" Checked="true" OnCheckedChanged="CreateSwapNetworkAll_CheckedChanged"
            AutoPostBack="true" />
        <asp:UpdatePanel ID="d" runat="server" UpdateMode="Conditional">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="CreateSwapNetworkCustom" EventName="CheckedChanged" />
                <asp:AsyncPostBackTrigger ControlID="CreateSwapNetworkAll" EventName="CheckedChanged" />
            </Triggers>
            <ContentTemplate>
                <asp:CheckBoxList ID="CreateSwapNetworkList" runat="server" Visible="false" ValidationGroup="ValidationGRPCreateSwap" />
            </ContentTemplate>
        </asp:UpdatePanel>

Code behind:
//Create swap - Custom network or All network
    protected void CreateSwapNetworkCustom_CheckedChanged(object sender, EventArgs e)
    {
        if (CreateSwapNetworkCustom.Checked == true)
        {
            con.Open();
            SqlCommand cmd = new SqlCommand("SELECT * FROM NetworkUserTBL WHERE UserID ='" + Session["UserID"] + "' AND Authed ='" + "1" + "'", con);
            SqlDataReader PrintUserNetworks = cmd.ExecuteReader();

            while (PrintUserNetworks.Read())
            {
                con2.Open();
                SqlCommand cmd2 = new SqlCommand("SELECT * FROM NetworkTBL WHERE ID ='" + PrintUserNetworks["NetworkID"] + "'", con2);
                SqlDataReader PrintNetworkInfo = cmd2.ExecuteReader();
                PrintNetworkInfo.Read();

                CreateSwapNetworkList.Items.Add(new ListItem(PrintNetworkInfo["Name"].ToString(), PrintNetworkInfo["ID"].ToString()));

                PrintNetworkInfo.Dispose();
                con2.Close();
            }

            PrintUserNetworks.Dispose();
            con.Close();

            CreateSwapNetworkList.Visible = true;
        }
        if (CreateSwapNetworkCustom.Checked == false)
        {
            CreateSwapNetworkList.Visible = false;
        }
    }
    protected void CreateSwapNetworkAll_CheckedChanged(object sender, EventArgs e)
    {
        if (CreateSwapNetworkAll.Checked == true)
        {
            CreateSwapNetworkList.Visible = false;
        }
        if (CreateSwapNetworkAll.Checked == false)
        {
            CreateSwapNetworkList.Visible = true;
        }
    }


Mit problem er at de 2 radio buttons kun virker den ene vej. Dvs. at hvis jeg trykker på Custom, så kommer min checkdownlist, men hvis jeg klikker tilbage på All, så sker der intet.
