RadSchedulerRecurrenceEditor Alone

Hi all,

I am new to the UI for ASP.NET AJAX. I am still learning. I am interested in using RadSchedulerRecurrenceEditor alone, not with RadScheduler. The problem I encounter now is that I see only the Recurrence label, and "Never" is selected in the dropdown box. I write the logic that reads the RecurrenceRule from Appointments.xml and assigns it to RecurrenceRuleText of the RadSchedulerRecurrenceEditor control, but the control does not show the entries from my RecurrenceRule. Can you please help? Thank you very much.

Radeditor moving from window 7 to windows 10

In a vb.net web form 2010 application that uses the rad editor, the development workstation uses windows 7 currently. In the near future, they will be using windows 10 workstations for development. The skin value for the radeditor uses a skin that points to windows7 as listed below:

<telerik:RadEditor ID="reLetterEditor"
            runat="server"
            Skin="Windows7"
            ContentFilters="DefaultFilters,PdfExportFilter"
            NewLineMode="Br"
            EditModes="Design,Preview,html"
            Width="100%"
            Height="800px"
            >

When the development workstation is changed to using windows 10, is there anything I need to be aware of concerned about?

Will changing the skin value to be "Windows10" be enough? Is that all I need to do except for testing the application?

Combobox Load on demand problems

I am trying to get the combobox to load on demand and be searchable but am having problems. I have followed the demos but can get it to work.
Here is what I have.

Aspx page:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" CollapseDelay="0"

ExpandDelay="0" Filter="StartsWith" ItemsPerRequest="10"

MarkFirstMatch="true" EnableAutomaticLoadOnDemand="True" EmptyMessage="-New Menu-"

ShowMoreResultsBox="True" EnableItemCaching="false" EnableLoadOnDemand="True" EnableVirtualScrolling="True">

<HeaderTemplate>

<table style="width: 275px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 175px; height: 13px">Name

</td>

<td style="width: 60px; height: 13px">ID

</td>

<td style="width: 40px; height: 13px">Grade

</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 275px" cellspacing="0" cellpadding="0">

<tr>

<td style="width: 175px;">

<%# DataBinder.Eval(Container.DataItem, "FullName")%>

</td>

<td style="width: 60px;">

<%# DataBinder.Eval(Container.DataItem, "StudentID")%>

</td>

<td style="width: 40px;">

<%# DataBinder.Eval(Container.DataItem, "DisplayGrade")%>

</td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

C# to bind

RadComboBox1.DataTextField = "FullName";

RadComboBox1.DataValueField = "StudentID";

RadComboBox1.DataSource = dt_students;

RadComboBox1.DataBind();

I get this error when I click on it.
"There was an error in the callback.s[]_$$__$$__$$_False_$$_"

Any help would be great thank you.

Unexpected behaviour of asp controls after page change in RadListView

I have a RadListView control, which has a asp button in Itemtemplate to delete the Item . I have a requirement to make all my controls in page read only. Intially in Page_PreRender event i am traversing through the all controls and their child controls and disabling them. Everything is working as expected. But when i change page of RadListView The asp controls which i have disabled them earlier are again getting enabled. Is this expected behaviour with RadListView combining with RadPager. Below are the properties i have set.

<telerik:RadAjaxManagerProxy ID="ADCleintsRadAjaxManagerProxy" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="ClientsRadAjaxPanel">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ClientsRadListView" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxPanel ID="ClientsRadAjaxPanel" runat="server"

LoadingPanelID="RadAjaxALoadingPanel" ViewStateMode="Disabled">

<telerik:RadListView ID="ClientsRadListView" runat="server"

ItemPlaceholderID="DrugsContainer"

AllowPaging="True" PageSize="4" DataSourceID="ClientsDataSource"

OnItemDataBound="ClientsRadListView_OnItemDataBound"

ViewStateMode="Disabled" OnNeedDataSource="ClientsRadListView_OnNeedDataSource" OnItemCreated="RadListView1_ItemCreated" >

I have checked the Button enable property in different events when i changed the page. Below are the sequence of page flow. When i changed the RadListView page> RadListView1_ItemCreated> Button.enabled property is true PageLoad > Button.enabled property is true Page_PreRender > first disabling all the form elements with a function > I found my Button enabled property is false here after disabling means my function is working fine. RadListView1_ItemCreated> This event is fired again and my button.enabled is true here. Please can any one help me with this?

RadioButtonList How to set Forecolor of the Text for the items

I have an ASP.Net page with VB.net code-behind.

I have a number of telerik controls on the page like the RadMenu, RadButtons, RadTextBox, RadLabel, etc.

The page has a dark near black background.

I have just added the telerik RadioButtonList. My default skin for all my ASP.Net pages is Office2007.

With the Office2007 skin, the text of the items in the RadioButtonList is Black. I need the text of the items to be White.

How to override the forecolor of the text of the items without affecting the other telerik controls on the page?

Sincerely,

Keith Jackson

In RadTreeView, I want to add an image at right side of the node text for each nodes

Hi Team,

In RadTreeView, I want to add an image at right side of the node text for all the nodes in Client- Side.

Description:
1. Dynamically, I am adding nodes in the client side and here I wanted to place an image at right side of the node text(find attached for how I wanted) and I tried with "farimage" property, Image index property as the value of "1" and tried with many ways. But, all are not working out.

In one way, I am able to achieve this, If I append an image with the text. But, I am getting an error ("A potentially dangerous Request.Form value was detected from the client ") while post occurs.

I would be helpful if you send me an example.
