Hello Telerik,
I'm tring to develop a custom designer for a simple user control I've done.

The problem I got is that the setter of my Custom user control (not designer) is not updated (and I got a js exception when loading)

Here're my classes (taking as example this link) :

Custom UserControl (the part it's intresting) :

private int _ProvaID = 5;

public int ProvaID

get

return _ProvaID;

set

_ProvaID = value;

The .js

Type.registerNamespace("SitefinityWebApp.Resources");

SitefinityWebApp.Resources.FormattedDownloadList_Designer = function (element)

SitefinityWebApp.Resources.FormattedDownloadList_Designer.initializeBase(this, [element]);

SitefinityWebApp.Resources.FormattedDownloadList_Designer.prototype =

initialize: function ()

SitefinityWebApp.Resources.FormattedDownloadList_Designer.callBaseMethod(this, 'initialize');

,

dispose: function ()

SitefinityWebApp.Resources.FormattedDownloadList_Designer.callBaseMethod(this, 'dispose');

,

refreshUI: function ()

var data = this._propertyEditor().get_control();

jQuery("#ProvaID").val(data.ProvaID);

,

applyChanges: function ()

var controlData = this._propertyEditor().get_control();

controlData.ProvaID = jQuery("#ProvaID").val();

The Designer .ascx :

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="FormattedDownloadList_Designer.ascx.cs"

Inherits="SitefinityWebApp.Resources.FormattedDownloadList_Designer" %>

<%@ Register Assembly="Telerik.Sitefinity" Namespace="Telerik.Sitefinity.Web.UI"

TagPrefix="sitefinity" %>

<%--<sitefinity:ResourceLinks ID="resourcesLinks" runat="server">

<sitefinity:ResourceFile AssemblyInfo=

"SitefinityWebApp.Controls.FormattedDownloadList, SitefinityWebApp, Version=4.0.1210.0, Culture=neutral, PublicKeyToken=null"

Static="true" />

</sitefinity:ResourceLinks>--%>

<div id="LibraryOption">

<label for="ProvaID"> Width</label>

<asp:TextBox runat="server" ID="ProvaID" Text=""></asp:TextBox>

</div>

and the Designer .cs

public partial class FormattedDownloadList_Designer : ControlDesignerBase

protected override void InitializeControls(Telerik.Sitefinity.Web.UI.GenericContainer container)

base.DesignerMode = ControlDesignerModes.Simple;

protected override string LayoutTemplateName

get

return "SitefinityWebApp.Resources.FormattedDownloadList_Designer.ascx";

public override IEnumerable<System.Web.UI.ScriptReference> GetScriptReferences()

var res = new List<ScriptReference>(base.GetScriptReferences());

var assemblyName = this.GetType().Assembly.GetName().ToString();

res.Add(new ScriptReference("SitefinityWebApp.Resources.FormattedDownloadList_Designer.js", assemblyName));

return res.ToArray();

public override IEnumerable<ScriptDescriptor> GetScriptDescriptors()

//This is taken from the forum....I've got ProvaID null here

ScriptControlDescriptor desc = new ScriptControlDescriptor(this.GetType().FullName, this.ClientID);

// desc.AddElementProperty("ProvaID", this.ProvaID.ClientID);

return new[] desc ;

The exception I got (and if I click on ignore in VS2010 it loads) is the one I've attached below ... the ProvaID's getter of my user control is called but the value is not displayed

What am I doing wrong? is there a way of understanding why I got this JS error?
Thanks
Ilaria

Hello,
I missed this piece of code :

SitefinityWebApp.Resources.FormattedDownloadList_Designer.registerClass('SitefinityWebApp.Resources.FormattedDownloadList_Designer', Telerik.Sitefinity.Web.UI.ControlDesign.ControlDesignerBase);

if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();

now it works... thanks
