How do I use Telerik in ASP.NET Razor (not MVC)?

I'm a little puzzled at where Telerik fits in with the ASP.NET framework when it comes to the Razor view engine. I have a ASP.NET Razor web site (not MVC, Telerik Razor documentation all points to MVC) but am at a loss as to how to integrate Telerik controls. Is there some documentation which will help me?

OnClientAppointmentInserting incorrect timeslot

Hi,

I am trying to get the selected time range for a new appointment and am getting incorrect information passed into the OnClientAppointmentInserting method. As shown in the screen shot "appointment selection.jpg" I select a time period of 10:30 am to 12:30 pm, I then right click and select new appointment. When the OnClientAppointmentInserting method is fired the start time is now 12:00 pm and the end time is now 12:15 pm (see "timeslot.jpg").

Am I missing something or is this an issue with the OnClientAppointmentInserting event?

Thanks

Gavin.

Here is my code

<telerik:RadScheduler ID="rsAppointments" runat="server"

DataEndField="AppointmentEndDate"

DataKeyField="PatientAppointmentID"

DataStartField="AppointmentStartDate"

DataSubjectField="AppointmentTypeID"

DataDescriptionField="AppointmentTypeID"

Height="600px" MinutesPerRow="15"

onnavigationcomplete="rsAppointments_NavigationComplete"

OnClientAppointmentInserting="OnInsertAppointment"

OnClientAppointmentEditing="OnEditAppointment"

GroupBy="Clinicians"

onappointmentcreated="rsAppointments_AppointmentCreated"

onappointmentupdate="rsAppointments_AppointmentUpdate"

onappointmentdelete="rsAppointments_AppointmentDelete">

<TimelineView UserSelectable="False" />

<ResourceTypes>

<telerik:ResourceType Name="Clinicians" KeyField="UserID" TextField="ClinicianName" ForeignKeyField="ClinicianID" />

</ResourceTypes>

<AppointmentTemplate>

<table border="0" cellpadding="3" cellspacing="0" width="100%">

<tr>

<td style="border: none;" rowspan="2"><asp:Literal ID="litContent" runat="server"></asp:Literal></td>

</tr>

</table>

</AppointmentTemplate>

<AppointmentContextMenuSettings EnableDefault="true" />

<TimeSlotContextMenuSettings EnableDefault="true" />

</telerik:RadScheduler>

function OnInsertAppointment(sender, args)

{

var slot = args.get_targetSlot();

var dteStart = slot.get_startTime();

var dteEnd = slot.get_endTime();

var res = slot.get_resource();

var resourceID = res.get_key();

var oManager = GetRadWindowManager();

var oWnd = oManager.getWindowByName("rwAppointment");

var URL = "AppointmentEdit.aspx?mode=insert&start=" + dteStart.toString("dd/MM/yyyy HH:mm:ss tt") +

"&end=" + dteEnd.toString("dd/MM/yyyy HH:mm:ss tt") +

"&cID=" + resourceID +

"&pid=" + <%= PatientID %>;

oWnd.setUrl(URL);

oWnd.show();

args.set_cancel(true);

}

Within the AppointmentInsert or AppointmentUpdate event handler, how can I get ASP.NET control references from an advanced form edit/insert template? I need to find an ASP.NET control in the template within these two events only, and use its value for save.

Thanks.

Argument Null Exception when using AddAjaxSetting

Hello,

I am working on an ASP.Net page (using VB) that dynamically builds a table and form. When the page loads and it's building the form and table there are a series of controls that I'm trying to create and add to an Ajax Manager (that is also created in code) but when I'm trying to do an AjaxManager.AjaxSettings.AddAjaxSetting(oCheckbox, oRadTextBox) I get an error:

ArgumentNullException was unhandled by user code.
Value cannot be null.
Parameter name: page

I was doing some research into the problem and found this post:
http://www.telerik.com/community/forums/aspnet-ajax/ajax/problem-when-using-radajaxmanager-in-umbraco.aspx

At the end of the post Maria Ilieva was following up with the original poster and said something about MasterPages and how the ajax manager is placed. I'm using master pages so I suspect that's my problem. The master page is very simple and has nothing more than formatting, style statements, logos, etc. The web form that uses the master page is where the ajax manager resides. I've paraphrased a stripped down simple version of the code here so you can see what I'm doing. I'm creating two controls, adding them to cells to a row and table then trying to add them to the ajax manager.

oCheckbox.ID = "chk1"

oCheckbox.AutoPostBack = True

oCell.Controls.Add(oCheckbox)

oRow.Cells.Add(oCell)

oRadTextBox.ID = "txtSerial"

oCell.Controls.Add(oRadTextBox)

oRow.Cells.Add(oCell)

oTable.Rows.Add(oRow)

oAjaxManager.AjaxSettings.AddAjaxSetting(oCheckbox, oRadTextBox)

The ArumentNullException error occurs on the last statement with the AddAjaxSetting method. How am I supposed to be calling this from the web form when using master pages?
