Hello,

I'm trying to load a DataTypeDefinition in the frontend (just need to display an Umbraco DropDown), but the values of the control are always the default values. Even after I change the value in the DropDownList and I press the save button the controls get it's old value back. Does someone know what I'm doing wrong?

Here is my code:

FrontPage:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Profile.ascx.cs" Inherits="MikzIntranet.UmbracoExtension.UserControls.Profile" %>
<asp:Panel ID="PnlProfile" runat="server" DefaultButton="LnkSave" CssClass="profileContainer">
    <table cellpadding="0" cellspacing="0">
        <tr>
            <td class="labelCell"><strong>Naam</strong></td>
            <td class="fieldCell"><asp:TextBox ID="TxtName" runat="server" ValidationGroup="Profile" CssClass="textbox"></asp:TextBox></td>
            <td class="validatorCell"><asp:RequiredFieldValidator ID="ReqValName" runat="server" ControlToValidate="TxtName" ErrorMessage="Voer uw naam in." ValidationGroup="Profile"></asp:RequiredFieldValidator></td>
        </tr>
        <tr>
            <td class="labelCell"><strong>Functie</strong></td>
            <td class="fieldCell"><asp:PlaceHolder ID="PlaceHolderFunction" runat="server"></asp:PlaceHolder></td>
            <td class="validatorCell"></td>
        </tr>
        <tr>
            <td class="labelCell">&nbsp;</td>
            <td class="fieldCell"><asp:LinkButton ID="LnkSave" runat="server" Text="Opslaan" OnClick="LnkSave_Click" ValidationGroup="Profile"></asp:LinkButton></td>
            <td class="validatorCell">&nbsp;</td>
        </tr>
    </table>
</asp:Panel>

Code behind:

    public partial class Profile : BaseUserControl
    {
        public dropdown _umbracoDropDown;

        #region Properties

        /// <summary>
        /// Return the MemberId stored in the ViewState. This property must first be set.
        /// </summary>
        private int MemberId
        {
            get
            {
                return Convert.ToInt32(ViewState["MemberId"]);
            }
            set
            {
                ViewState["MemberId"] = value;
            }
        }

        #endregion

        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);

            //Get the function datatype and add it to the PlaceHolder.
            DataTypeDefinition functionDataType = DataTypeDefinition.GetDataTypeDefinition(Configuration.FunctionDataType);
            _umbracoDropDown = (umbraco.editorControls.dropdown)functionDataType.DataType.DataEditor;
            PlaceHolderFunction.Controls.Add(_umbracoDropDown);
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //Get the current member his profile.
                MemberProfile memberProfile = ControllerLayer.GetMemberProfile();

                //Store the MemberId in the ViewState.
                MemberId = memberProfile.MemberId;

                //Set the normal properties.
                TxtName.Text = memberProfile.MemberName;

                //Set the properties.
                _umbracoDropDown.ID = "DdlFunction";
                _umbracoDropDown.CssClass = "dropdown";
                SetSelectedListItem(_umbracoDropDown, memberProfile.Function);
            }
        }

        /// <summary>
        /// Update the profile of a member.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void LnkSave_Click(object sender, EventArgs e)
        {
            //Create a new MemberProfile-object with the values from this page.
            //In here _umbracoDropDown.SelectedValue should be the value the user selected, but it's always the default value.
            MemberProfile memberProfile = new MemberProfile(MemberId, TxtName.Text, _umbracoDropDown.SelectedValue);

            //Update the profile.
            ControllerLayer.UpdateMemberProfile(memberProfile);
        }
    }

I hope someone can help me.
