I want to use your filtered combobox as given in web link: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx
But I am getting "CS0234: The type or namespace name 'QuickStart' does not exist in the namespace 'Telerik' (are you missing an assembly reference?)" error.
I tried to find QuickStart in my telerik package but can not found this file/dll. Please help me to implement the required control and get the proper dll.

Are you trying to run the demos from the
Telerik\RadControls for ASP.NET AJAX Q1 2012\Live Demos\RadControlsExamples.sln?
Or maybe you just copy / paste the code from the online demos?
If so, note that they include a reference to the QuickStart namespace. Its definition / files can be found in the
\Telerik\RadControls for ASP.NET AJAX Q1 2012\Live Demos\App_Code\QuickStart folder of your local installation.
Let me know if this helps.

Currently the code files related to the site itself are here:
RadControls for ASP.NET AJAX Q3 2013\Live Demos\App_Code\QSFCommon
When you open the demo solution you can use the IDE tools to navigate to the code that creates the user control to easily find the needed files.

but it throws an error here
<qsf:ConfiguratorPanel runat="server" ID="InternetExplorerConfigurator" Enabled="true"
Title="Internet Explorer Settings" Expanded="false" Style="text-align: left;"
HorizontalAlign="Right" Width="370px">
It says "Unknown server tag 'qsf:ConfiguratorPanel'"
I have added this at the header
<%@ Register TagPrefix="qsf" Namespace="Telerik.QuickStart" %>
Hi Shiba,
Have you also added the class from the App_Code folder? You also need to trace the resources it needs and add them too (image sprite, stylesheet, script).
For your convenience, I extracted them from the demo site and I attached here a small sample that shows a working panel.

Dear Telerik Team
I am using trial version of telerik
I am facing this Error
while using <telerik:RadAutoCompleteBox> i got error in designer page as Quickkstart reference was not fount and i downloaded Telerik Quick Start Dll file and added in the reference then i got another error following below
Error 54 The type or namespace name 'DropDownList' does not exist in the namespace 'Telerik.QuickStart' (are you missing an assembly reference?)
kindly sort it out
All QuickStart related code is available in the installation of our Demo site, available for download from your Telerik accounts. I am attaching a very simple web site, including all needed Quick start controls code, so you can examine it on your side.
In order to use the QuickStart controls in a Web Application, you need to add their code to the App_Code folder and make sure that their namespace match the application namespace as well. You will also need to make sure that the Build action of all QuickStart related files is set to "Compile":
As this is a general programing task which has to be handled by each developer, I would advice that you go through the steps in the following article and see what you might have missed during the integration process:

Hello,
I can not find these files [\Telerik\RadControls for ASP.NET AJAX Q1 2012\Live Demos\App_Code\QuickStart ] even this path in my 'Telerik folder' on C:\ drive. Can you please tell me, What i need to install from telerik?
thanks,

Hello,
I have same problem but i have installed Telerik, still i have same problem and it have not solved my problem. I can not find the file in the given path (\Telerik\RadControls for ASP.NET AJAX Q1 2012\Live Demos\App_Code\QuickStart ).
Thanks.
In order to have the mentioned folder you need to have the 2012 Q1 version of the controls installed - can you verify that you have done so?
Please note that as of Q1 2013 the demos source code is shipped with a separate installation. If you are using a version released after that you can download the demos installation from your Telerik account following the steps below:
- Log into your Telerik account.
- Go to Products & Subscription / DevCraft Complete option
- Click on the big blue Download button on the right side of the loaded screen
- Find the UI for ASP.NET AJAX section and click the Browse all product files option on its right
- Download the Demos Installation file.
I hope this helps.

Hello Telerik,
I have done the following steps for getting QuickStart:
1. Registered the Telerik.QuickStart namespace at header
<%@ Register TagPrefix="qsf" Namespace="Telerik.QuickStart" %>
2. Added the QuickStart files to the App_Code folder from program files:
C:\Program Files (x86)\Telerik\UI for ASP.NET AJAX Q1 2016\Live Demos\App_Code\QSFCommon
3. Made sure the Build Action of all added QuickStart files are set to "Compile"
After this, I'm getting a deluge of compile errors "Statement cannot appear outside of a method body/multiline lambda" and "'Class' statement must end with a matching 'End Class'". This appears like the compiler is trying to interpret CS code with VB code.
Do you have any suggestions? Thanks.
Hi,
Depending on your setup, our App_Code folder may contain files with different languages and to deal with this, you should all an entry to your web.config similar to the following one taken directly from our demos' web.config:
<
compilation
debug
=
"true"
targetFramework
=
"4.0"
>
<
codeSubDirectories
>
<
add
directoryName
=
"Grid_VB"
/>
</
codeSubDirectories
>
I also advise you follow the steps from the "Isolate this demo as a stand-alone application" link right above the source code view so you can get rid of the additional namespaces used by the demos site.

Thanks for your reply, but I have actually found that the real issue. The project I'm working on is a Visual Basic project, so the QuickStart files (which are in CSharp) don't compile.
Do you offer the same QuickStart files and functionality in Visual Basic instead of CSharp?
Hi Torrey,
We don't. They are code files we have created for the sake of the demo site and we write in C#. You can start from code converters (like this one) to translate the existing code.
Regards,
Telerik

Ok, thanks.
I am attempting to identify and convert only the files necessary for getting the basic paging grid to work. Please see here.
Although I've made progress, but I'm running into numerous errors, like the following: 'IsNullOrWhiteSpace' is not a member of 'String'. I found later that this method was introduced in .NET 4.0; however, our framework is targeted for 3.5.
So it seems like the QuickStart code was intended for .NET 4.0 and above. Is that correct?
Do you have a version of QuickStart that works with .NET 3.5 that perhaps you have compiled into a DLL?
Hi Torrey,
Yes, the demos site targets .NET 4.0 and is not optimized for .NET 3.5. We do not have a version for 3.5 nor a compiled assembly of it, because it is a WebSite type of project.
Regards,
Telerik
Hi Torrey,
Let me clarify something—the Telerik.QuickStart namespace is only created for the demos site. It provides the demos with information boxes, configuration panels and so on. It does not affect the controls themselves (like the grid), and it is not required at all for you to use the controls.
So, the short answer to your question is - there are no paging styles for the grid defined in Telerik.QuickStart, and all of the available ones from Telerik.Web.UI should work under .NET 3.5 as well.
Regards,
Telerik

Ok, I see. That makes sense.
We will go with an example on the demo site that doesn't use the QuickStart namespace, and build from there.
Thanks for your help and clarification.

I Have UI for Asp.NET Ajax Q2 2016 and there is no folder with the name of liveDemos\App_code so what will i do

I Have UI for Asp.NET Ajax Q2 2016 and there is no folder with the name of liveDemos\App_code so what will i do
and give a valid answer above discussion answer are not working correctly plz provide a helpful answer
Actually, the LiveDemos\App_Code folder does exist as you can see in this screenshot.
Make sure that you have installed the right installation, which include the demo files such as:
Telerik_UI_for_ASP.NET_AJAX_2016_2_607_Demos_Dev.msi
You can find more information how to isolate the code from the demo app at http://demos.telerik.com/aspnet-ajax/Common/QSFInstructions/Instructions.html

Hola Francisco,
The Telerik.QuickStart namespace is part of the demo website and is used only for the purposes of the demos.
If you do want to use it, you can find its code in the App_Code folder of the demo site you can download it from your account: Go to https://www.telerik.com/account/product-download?product=RCAJAX and download Telerik_UI_for_ASP.NET_AJAX_20xx_x_xxx_Demos_Dev.msi.
Alternatively, the Isolate this demo as a stand-alone application page shows how to remove it from the demos. This page is available as a link on each demo along with a download option with ready-to-use demo files (Download demo code files):
If you experience any troubles isolating a specific demo, please let us know exactly which one and we can send you a runnable sample app with it.
