RadComboBox inside Composite control javascript error

Hi,
I am writing a server composite control which would reuse some of the RadComboBox functionality. When running a page which uses that control I am getting a JavaScript error (see the bottom of my post). I have narrowed the problem down to the RadComboBox itself. Is there any known fix to that?

Here is my server control (stripped as much as I can to produce the problem) :

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Linq;

using System.Text;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

namespace ServerControl1

{

[ToolboxData("<{0}:ScapaLoad runat=server></{0}:ScapaLoad>")]

public class ScapaLoad : CompositeControl

{

RadComboBox _combo;

[

Category("Data"),

Description("Data source ID for populating combo box"),

PersistenceMode(PersistenceMode.Attribute)

]

public string DataSourceID

{

get

{

EnsureChildControls();

return _combo.DataSourceID;

}

set

{

EnsureChildControls();

_combo.DataSourceID = value;

}

[

Category("Data"),

Description("Database field with value to be used as a value of each combo box element"),

PersistenceMode(PersistenceMode.Attribute)

]

public string DataValueField

{

get

{

EnsureChildControls();

return _combo.DataValueField;

}

set

{

EnsureChildControls();

_combo.DataValueField = value;

}

[

Category("Data"),

Description("Database field to be used as a visible text for chosen element from combo box"),

PersistenceMode(PersistenceMode.Attribute)

]

public string DataTextField

{

get

{

EnsureChildControls();

return _combo.DataTextField;

}

set

{

EnsureChildControls();

_combo.DataTextField = value;

}

protected override void CreateChildControls()

{

Controls.Clear();

_combo = new RadComboBox();

Controls.Add(_combo);

}

protected override void RecreateChildControls()

{

EnsureChildControls();

}

protected override void Render(HtmlTextWriter writer)

{

AddAttributesToRender(writer);

_combo.RenderControl(writer);

}

A page using the control (again, stripped down to just the control itself) :

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<%@ Register Assembly="ServerControl1" Namespace="ServerControl1" TagPrefix="aspSample" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"/>

<asp:LinqDataSource ID="LinqDataSource1" runat="server" EnableDelete="true"

</asp:LinqDataSource>

<aspSample:ScapaLoad ID="ScapaLoad1" runat="server"

DataSourceID="LinqDataSource1" DataValueField="Name" DataTextField="Name" />

</div>

</form>

</body>

</html>

The javascript error I am getting is:

'undefined' is null or not an object Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3ac9d03845-da3c-45e9-ab05-79ee502af576%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2011.2.712.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3af9722142-3e1c-4803-86df-ecfc0d24f144%3a16e4e7cd%3af7645509%3a24ee1bba%3af46195d3%3a1e771326%3aaa288e2d, line 6 character 74101

Please help, it is urgent. If you need any additional data please let me know and I will provide it if I can.

Thanks,

Specialday not disabled in other month

Hello All,

I have a very simple Calendar with 2 months, Sep and Oct
The SpecialDay is Oct first an must be only visible on the second month in the calendar.
So far so good.

In the first month of the calendar this date is not visible as a SpecialDay but when I hover over the date then the date lights-up while it must be disabled and when hover-off then the style is applied from the special date.

The screen dump’s show before hover and after hover.

I set the date on DayRender and compare the date to e.Day and the Month.

The tooltip is only visible on the second calendar month so I know the a have the correct day and month.

How can I disable the days form the other months without setting the property ShowOtherMonthsDays="false" ?

<head runat="server">

<title></title>

<style type="text/css">

.RadCalendar .event_future

{

border: 1px solid Green !important;

background-color: Lime;

}

.RadCalendar .rcOtherMonth a, .RadCalendar .riDisabled a

{

cursor: default;

}

</style>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadCalendar ID="RadCalendar1" runat="server" CultureInfo="nl-NL" EnableMultiSelect="False"

EnableMonthYearFastNavigation="False" FirstDayOfWeek="Monday" MultiViewRows="2"

TitleFormat="MMM" ShowDayCellToolTips="false" Skin="WebBlue" TitleAlign="Center"

UseColumnHeadersAsSelectors="False" UseRowHeadersAsSelectors="False">

</telerik:RadCalendar>

</form>

</body>

</html>

Protected Sub RadCalendar1_DayRender(sender As Object, e As Telerik.Web.UI.Calendar.DayRenderEventArgs) Handles RadCalendar1.DayRender

Dim SpecialDay As Date = DateValue("1-10-2011")

If e.Day.Date = SpecialDay AndAlso e.View.MonthStartDate.Month = SpecialDay.Month Then

e.Day.IsSelectable = True

e.Day.IsDisabled = False

e.Cell.ToolTip = "SpecialDay"

e.Cell.CssClass = "event_future"

Else

e.Day.IsSelectable = False

e.Day.IsDisabled = True

e.Cell.CssClass = "riDisabled"

End If

Me.RadCalendar1.SpecialDays.Add(e.Day)

End Sub

Best regards,

Marco

Selecting which Edit Template controls to show programmatically

Hi

I am working on a grid that allows for in-line editting and I'm using edit templates.

I have a couple of columns that are inter-related.

The first column allows the user to pick from one of three choices when in edit mode,

No Sort, Sort Ascending, or Sort Descending. I am using a ComboBox in this column's ItemTemplate.

The second column allows the user to determine the sort precidence, 1, 2, 3, etc.
For this column I am using a NumericTextBox with SpinUp and SpinDown buttons.

If the first column has 'No Sort' as its value I would like to prevent the Edit Control for the second
column from appearing when I put the row into edit mode.

I have managed to create some client-side code that hides and shows the NumericTextBox and its spin buttons
and I invoke this code on a selection change in the first column's ComboBox. This works acceptably.

However I have been unable to come up with a method for not showing the NumericEditControl when
I put the row into edit mode.

Any ideas on how to do this with client, or server side could wold be a great help.

 master.fireCommand("InitInsert", "");

Grid correctly creates a new row but I never get to ItemCommand handler in codebehind. Why?
Thank you.
