WCF - The server method 'LoadClients' failed

I followed the below tutorial link to populate a RadComboBox using WCF service.
This works fine on localhost but when I deploy it on the server I'm getting an error "The server method 'LoadClients' failed" whenever this service is called.

http://www.telerik.com/help/aspnet-ajax/combobox-load-on-demand-wcf-service.html

WebConfig:

<system.serviceModel>

<behaviors>

<endpointBehaviors>

<behavior name="WCFClientsAspNetAjaxBehavior">

<enableWebScript/>

</behavior>

</endpointBehaviors>

</behaviors>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

<services>

<service name="WCFClients">

<endpoint address="" behaviorConfiguration="WCFClientsAspNetAjaxBehavior" binding="webHttpBinding" contract="WCFClients"/>

</service>

</services>

<bindings>

<webHttpBinding>

<binding name="webBinding">

<security mode="Transport">

</security>

</binding>

</webHttpBinding>

WCFClients.svc:

<OperationContract()> _

Public Function LoadClients(ByVal context As RadComboBoxContext) As RadComboBoxData

'The RadComboBoxData object contains all required information for load on demand:

' - the items

' - are there more items in case of paging

' - status message to be displayed (which is optional)

Dim result As New RadComboBoxData()

' Dim connectionStr As String = Current.Session("ConnectionString").ToString

Dim connectionStr As String = "MyConnectionString"

Dim TransMgr As New TransmgrClientsDataContext(connectionStr)

'Get all items from the Customers table. This query will not be executed untill the ToArray method is called.

Dim allCustomers = From c In TransMgr.Clients _

Order By c.LastNm _

Select customer = New RadComboBoxItemData With _

{.Text = c.LastNm & " " & c.FirstNm, .Value = Convert.ToString(c.Clnt_No)}

'In case the user typed something - filter the result set

If Not [String].IsNullOrEmpty(context.Text) Then

allCustomers = allCustomers.Where(Function(item) item.Text.StartsWith(context.Text))

End If

'Perform the paging

' - first skip the amount of items already populated

' - take the next 10 items

Dim customers = allCustomers.Skip(context.NumberOfItems).Take(10)

'This will execute the database query and return the data as an array of RadComboBoxItemData objects

result.Items = customers.ToArray()

Dim endOffset As Integer = context.NumberOfItems + customers.Count()

Dim totalCount As Integer = allCustomers.Count()

'Check if all items are populated (this is the last page)

If endOffset = totalCount Then

result.EndOfItems = True

End If

'Initialize the status message

result.Message = [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", endOffset, totalCount)

Return result

End Function

aspx:

<script type ="text/javascript" >

function validateCombo(source, args) {

args.IsValid = false;

var combo = $find(source.controltovalidate);

var selectedItem = combo.get_selectedItem();

if (selectedItem) {

var value = selectedItem.get_value();

if (value > 0) {

args.IsValid = true;

}

</script>

<telerik:RadComboBox runat="server" ID="rcbClients" Height="100px" EnableLoadOnDemand="true"

ShowMoreResultsBox="true" EnableVirtualScrolling="true" AllowCustomText="false"

EmptyMessage="Type lastname ...">

<WebServiceSettings Path="WCFClients.svc" Method="LoadClients" />

<asp:CustomValidator ID="cvClients" runat="server" ClientValidationFunction="validateCombo"

SetFocusOnError="true" ErrorMessage="Please select a client from Dropdown" ControlToValidate="rcbClients">*

</asp:CustomValidator>

Thank you for your help!!

Design problem in Telerik 2011 ...

Hi,

Initially, My Application referenced with Telerik 2008 version and It accessed custom themes from the

App_themes folder. It was working fine. Now, I have updated the telerik version 2011. I am surprised to see that all my css

are not working properly. Application Design failed in all radcontrols like RadGrid,RadTreeview etc.,

I have read documentation in the below url,

http://www.telerik.com/help/aspnet-ajax/grid-appearance-creating-new-skins.html

For RadGrid Design, I did the following,

I have changed some class names in the custom.css file.

.RadGrid to .RadGrid_Office2007 and .MasterTable_2007 to .rgMasterTable.

After changing this, I have got some decent alignment of this grid. But, I am not able

to retain the original design. I have both the versions (Telerik) of this application,

not able to fix up the design problem exists in the latest version (2011).

Please see the screenshot attached herewith.

Please do the needful.

Thanks,

V. Raguraman.

[Solved] Single Column In DetailsTable

I am working with version 2011.3.1305.35 of the RadGrid. I have a wide grid with 19 columns. There is an additional field I need to add that contains comments, which by its self can be 1000 characters long. If I add that column to the end of the grid most of the data is cut off. What I want to do now is put that comments column in a details table so the user can click the expand icon and view the comments. I think I have it set up correctly however, there is code in the ItemCreated event that tries to run when the expand icon is clicked. What is the best way to determine if the item being created is part of the details table?

Here is how I have the set grid setup:

<telerik:RadGrid ID="tGrid" runat="server" AllowPaging="True" AllowCustomPaging="true"

PageSize="500" AllowSorting="True" AutoGenerateColumns="False" CellSpacing="0"

OnNeedDataSource="tGrid_NeedDataSource" AllowMultiRowSelection="true" OnItemCreated="tGrid_ItemCreated"

OnDataBound="tGrid_DataBound">

<PagerStyle AlwaysVisible="True" Position="Top" />

<MasterTableView Width="100%" DataKeyNames="schedID" ClientDataKeyNames="schedID">

<Columns> .... </Columns>

<DetailTables>

<telerik:GridTableView AdditionalDataFieldNames="schedComments" DataKeyNames="SchedID">

<Columns>

<telerik:GridBoundColumn DataField="schedComments" Display="true" UniqueName="schedComments"

SortExpression="schedComments">

<HeaderStyle Width="100%"></HeaderStyle>

<ItemStyle Wrap="true" />

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

</MasterTableView>

</telerik:RadGrid>

widgets raddock and server controls

There seems to be a lot of talk about widgets these days.
Any specific Telerik solutions ?
I was looking at using a rad dock project as the main window.
Also develop some server controls in separate projects and use them the the main project.
Add them as toolkit items perhaps.
The server control should be stand alone.
Is this possible
Is this the best solution
Any advise please.
Regards
Jim

Chnage Font of All text in ContentArea

I'm implementing a mail for using RadEditor.

I need to be able to switch between Html and Plain Text.

I have a control on the page to do the switch, but I'm struggling with the code to actually update what the user sees in the editor.

Specifically, I'm trying to implement Outlook-like functionality so that, if they select Plain Text, all the formating is removed from any existing content and the font is switched to a non-proportional one.

I'm calling this when the format selection changes ...

setTimeout(function ()

{

sender.fire('FontName', { value: 'Courier New' });

}, 300);

and whilst this changes the selected font, it doesn't change any existing text.

Is there a way for me to select all of the content before calling the .fire method?

Input Manager and Invalid Javascript Validation Code

I have a contact us form that has been built and uses a RadInputManager to validate the input client side. The JavaScript that is created by the Input Manager seems to be invalid JavaScript as the variable name it uses are just numbers, e.g. var 0 = ...., and var 1 = ...

I have put a test page together which just includes two textboxes and a submit button to demostrate this. To view the page see http://learnbigteachbig.rocktime.net/test.aspx. The HTML for the page is also below.

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>

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

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

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

<div>

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

</telerik:RadScriptManager>

<telerik:RadInputManager ID="RadInputManager1" runat="server" EnableEmbeddedSkins="True"

EnableEmbeddedBaseStylesheet="False">

<telerik:TextBoxSetting ClearValueOnError="False" EmptyMessage="Full name"

ErrorMessage="Your full name is required">

<TargetControls>

<telerik:TargetInput ControlID="fdFullName" />

</TargetControls>

<Validation IsRequired="True" ValidationGroup="ContactUs" />

</telerik:TextBoxSetting>

<telerik:RegExpTextBoxSetting ClearValueOnError="False" EmptyMessage="Please enter your email address"

ErrorMessage="A valid email address is required" ValidationExpression="[^@]+@[^\.]+\..+">

<TargetControls>

<telerik:TargetInput ControlID="fdEmailAddress" />

</TargetControls>

<Validation IsRequired="True" ValidationGroup="ContactUs" />

</telerik:RegExpTextBoxSetting>

</telerik:RadInputManager>

<asp:TextBox ID="fdFullName" runat="server" ValidationGroup="ContactUs"></asp:TextBox>

<br /><br />

<asp:TextBox ID="fdEmailAddress" runat="server" ValidationGroup="ContactUs"></asp:TextBox>

<asp:Button ID="btnSubmit" runat="server" Text="Submit" ValidationGroup="ContactUs" />

</div>

</form>

</body>

</html>

The Javascript error that I get is

Error: missing variable name
Source File: http://learnbigteachbig.rocktime.net/test.aspx
Line: 79, Column: 4
Source Code:
var 0 = document.all ? document.all["0"] : document.getElementById("0");

I believe this is because variable names in JavaScript must begin with a letter, $ or _ to be valid. Is there something I need to add to the Input Manager to fix the problem?
