Html in node's text - Q1 2012

I've just installed Q1 2012 and I have a display problem with my treeviews. The html in node's text is displayed as is (see screenshot).
I generate the treeviews in code:

...

var title = String.Format(

"Unclassified <span style='font-size:9px'>({0})</span>", nb);

RadTreeNode unclassified = new RadTreeNode(title, "-2");

...

What is the fastest fix?

Validating grid in Insert mode

<telerik:GridTemplateColumn HeaderText="Image Url">

<ItemTemplate>

<asp:Label ID="lblImageUrl" runat="server" Text='<%# ShortenText.Shorten(Eval("imageURL"), 20) %>' />

</ItemTemplate>

<EditItemTemplate>

<asp:TextBox ID="txtImageUrl" runat="server" Text='<%# Eval("imageURL") %>' /><asp:RequiredFieldValidator

ID="ImageUrlValidator" runat="server" ErrorMessage="Image URL is required!"

ControlToValidate="txtImageUrl" Text="*" ValidationGroup="AdvertsGroup" /><asp:RegularExpressionValidator

ID="ImageUrlValidator1" runat="server"

ErrorMessage="Image URL can be only image path!" Text="*"

ControlToValidate="txtImageUrl"

ValidationExpression="http(s?)://([\w-]+\.)+[\w-]+(/[\w- ./]*)+\.(?:gif|jpg|jpeg|png|bmp|GIF|JPEG|JPG|PNG|BMP|Gif|Jpg|Jpeg|Png|Bmp)$"

ValidationGroup="AdvertsGroup" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Navigate Url">

<ItemTemplate>

<asp:Label ID="lblNavigateUrl" runat="server" Text='<%# ShortenText.Shorten(Eval("navigateURL"), 20) %>' />

</ItemTemplate>

<EditItemTemplate>

<asp:TextBox ID="txtNavigateUrl" runat="server" Text='<%# Eval("navigateURL") %>' /><asp:RequiredFieldValidator

ID="NavigateUrlValidator" runat="server" ErrorMessage="Navigate URL is required!"

ControlToValidate="txtNavigateUrl" Text="*" ValidationGroup="AdvertsGroup" /><asp:RegularExpressionValidator

ID="NavigateUrlValidator1" runat="server" ErrorMessage="Navigate URL should be valid internet url!"

ControlToValidate="txtNavigateUrl" Text="*"

ValidationExpression="http(s)?://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?" ValidationGroup="AdvertsGroup" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

Basically they should not be able to insert anything but a valid image path (URL) in the txtImageUrl and valid target url in the txtNavigateUrl fields. Both fields are required. How to achieve that? Obviously the validators i have there are ignored when i click Insert link (insert mode).

Thank you

Problem with 2012.1.215.35 version

We encountered following problems with the version 2012.1.215.35

1. Enter button stopped working for all the pages, if focus is on any of the other controls on the page. For example , in login page, the default onload cursor was on username field, if we just pressed entered, it did not work, if we clicked on any other point on the page and clicked enter, it worked as expected.

2. RadDatePicker control - behavior changed for some pages- if the date field is clicked, in first click, it was highlighting the date and showed the calendar control in second click.

After downloading the version 2011.3.1305.35, these problems were gone.

Thanks

Headers still drag when "AllowDragToGroup" = false

Hello,

I am using a RadGrid control, and as it currently stands, you can drag a grouping field (with the tool tip "Drag out of the bar to ungroup"), even though "AllowDragToGroup" = false. This is causing a javascript error "Sys.WebForms.PageRequestManagerServerErrorException".

I can't find an option to disable the dragging of this field, does anyone have a solution?

Thanks for any help

Paste problems

I've got a radEditor on a form.

I was doing a bit of testing and so went to the BBC home page and selected all the content on the page and copied it then pasted it to my editor.

You can see the results on this Jing video.

I'd be gratefule for any comments on how I might prevent either of the results shown in the video from occurring.

AllowDelete=false and other functions

I am populating a Rad Scheduler using a WCF services, some of the items cannot be deleted so I have set AllowDelete to be false this does not seem to work and when I hover over the appointment the delete image still appears.

I have also tried to set some other information based on whether the appointment is a parent or child and this does not seem to work either, see my code below. The subject of the appointment changes to be either "Parent: ...." or "Child: ...." so the IF statement is working correctly. But the other changes I am trying to make do not seem to work correctly.

Am I adding the appointments incorrectly/is there another way to do this that will work.

Public Overloads Overrides Function GetAppointments(ByVal Owner As RadScheduler) As IEnumerable(Of Appointment)

Dim AppointmentsList As New List(Of Appointment)

'get a list of appointments to add and put them in the list above

Do While Rs.ReadNext

Dim AppointmentItem As New Appointment

Slot.Fill(Rs.ReadRow)

AppointmentItem.Start = Slot.Start_DT.Value

AppointmentItem.End = Slot.End_DT.Value

AppointmentItem.AllowEdit = False

AppointmentItem.ID = Slot.GUI.Value

If Slot.ParentGUI.IsNull Then

AppointmentItem.Subject = "Parent: " & Slot.Name.Value

AppointmentItem.AllowDelete = False

AppointmentItem.ContextMenuID = "SchedulerAppointmentContextMenuDelete"

Else

AppointmentItem.Subject = "Child: " & Slot.Name.Value

AppointmentItem.RecurrenceParentID = Slot.ParentGUI.Value

AppointmentItem.AllowDelete = False

AppointmentItem.BackColor = System.Drawing.Color.Black

AppointmentItem.ForeColor = Drawing.Color.Pink

AppointmentItem.ContextMenuID = "SchedulerAppointmentContextMenuNothing"

' have tried this too, AppointmentItem.ContextMenuID = Nothing

End If

AppointmentsList.Add(AppointmentItem)

Loop

Rs.Close()

Return AppointmentsList

End Function

How to implement automatic insert and intersept that call to add IdFirm property to object and then save it database.

A minor cosmetic suggestion

Most end-users, if they recognise the word "Ajax" at all, prolly still think it is a product to clean the bathtub with.

Consider changing the default text for the Spell Check button from "AJAX Spellchecker to "Spellchecker"
