RecurenceParent is not visible, children are

In my implementation, I have some parent appointments that are visible=false. This is because the parent may belong to another user (not visible), and the single occurrence of an appointment is moved to the current user (current user's appointments are visible).

Originally, I did not include any appointments that were not of the current user, but this meant that the current user could not edit the single occurrence of their appointment, because it happened to be part of a series that originally belonged to another user.

Now, my scheduler loads in all appointments for the current user, and also includes any parent appointments, and sets parent appointments that belong to other users to visible=false.

This seemed to be working, except that the parent has a 'RecurrenceRule', so the scheduler automatically parses the rule and builds the recurring appointments. The recurring appointments are visible, even though the parent is visible=false. How can I force the parsed recurring appointments to be visible=false?

I tried setting the parent RecurrenceRule to null in AppointmentDataBound, and that prevents the recurring appointments for other users from being generated, but when you delete the current user's single occurrence, it throws an exception that the scheduler could not parse the parent RecurrenceRule (not surprisingly since I manually removed it).

Any ideas?

Problem by RadChart heigth setting

Dear Telerik Team,

we would like to ask how to strongly define RadChart's heigth. The heigth is set up in according to the size of chart's legend currently. Our chart has 192 series, in other words 192 items in the legend. The heigth of the chart is adjusted to the heigth of the legend regardless to the fact whether the legend is hidden or shown bellow. Here's our code snippet of the RadChart settings:

radChart.ClearSkin();

radChart.Skin = Skin;

radChart.SeriesOrientation = ((RadChartEntity)Session[radChart.ID]).Orientation;

radChart.AutoLayout = true;

radChart.PlotArea.Appearance.Dimensions.Width = 500;

radChart.PlotArea.Appearance.Dimensions.Height = 500;

radChart.PlotArea.EmptySeriesMessage.TextBlock.Text = "No data";

radChart.PlotArea.XAxis.IsZeroBased = false;

radChart.PlotArea.XAxis.AutoScale = false;

radChart.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;

radChart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 45;

radChart.PlotArea.XAxis.Appearance.LabelAppearance.CompositionType = LabelItemsCompositionTypes.RowImageText;

radChart.PlotArea.XAxis.Appearance.LabelAppearance.Position.AlignedPosition = AlignedPositions.Top;

radChart.Appearance.FillStyle.FillType = FillType.Solid;

radChart.Appearance.TextQuality = TextQuality.ClearTypeGridFit;

radChart.Appearance.Border.Visible = false;

radChart.Legend.Appearance.ItemTextAppearance.MaxLength = 20;

radChart.Legend.Appearance.Position.AlignedPosition = AlignedPositions.TopRight;

//radChart.Legend.Appearance.Overflow = Overflow.Row;

radChart.ChartTitle.Appearance.Position.AlignedPosition = AlignedPositions.TopLeft;

radChart.ChartTitle.Appearance.Position.Auto = false;

Let us also remark, the heigth of the RadChart equals to 600px a the width of the RadChart equals to 1000px.

<telerik:RadChart ID="radChart" runat="server" Height="600px" Width="1000px" EnableViewState="false">

</telerik:RadChart>

We attached the image of the chart for the illustration as well.
We'll be very grateful for any suggestions about solving such the problem.

Kind regards,
SCT

How to change the default protocol(Http Get or Post) of RadAjax controls

Hi,

I am currently researching on whether to use Http Get or Post in my Ajax Enabled website.
Can you tell me what protocol does the RadAjax controls like RadAjaxPanel use by default?(I think it uses Http Post)
Also can you tell me what should I do If I have to change the Protocol.
I would be extremely thankful if I can get a quick response.

Thanks in advance.

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" %>

<body>

<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
