I’ve been noticing that people use the word “callback” for almost any request to the server, but in ASP it has its own meaning and there are many other ways to call the server. So, I wanted to make a few clarifications and a quick list.

After the official release of our new Add OpenAccess Service wizard you have shown some great interest in using it to shorten the efforts for creating the Web Services and start developing your N-Tier solution. As we are always trying to help you achieve your goals faster and easier, we decided to enhance our resources on the matter with two video tutorials, covering all you need to know about using the wizard for generating WCF Plain Services and WCF Data Services.  

WCF Plain Services

As many of you already know, for exposing your OpenAccess Domain Model through a Plain Service, we are generating a layer of Data Transfer Objects....

As many of you may know, KendoUI is a really awesome new JavaScript framework that combines everything needed for modern JS development into one sweet package.  One of the features it provides is the ability to bind different UI controls to various data sources; so in this blog I will show you how OpenAccess ORM can be leveraged on the backend, and KendoUI can take care of the front end!

Getting Set Up

To get started create a new ASP.Net Empty Web Application.

Note: You can really use any web based project template you like, in this walkthrough I just chose to start with nothing. :)

Spatial data is all the rage, everyone wants a map in their application to quickly visualize data.  In a previous blog I showed how you could query, and display, SQL Spatial data on RadMap for WPF using Telerik OpenAccess ORM.  In this blog, I will show you how to display the data on RadMap for Silverlight.  This adds a slight twist because we need to transport the SQL Spatial data across a service boundary, but thanks to some updates in RadMap this is still an easy process; so lets take a look!

Database Setup

The first thing we need is some spatial data. In...

After working a bit with the Silverlight Report Viewer for Telerik Reporting, it seemed only natural to write a quick post to explain how exactly the Reporting WCF Service (located here in the help file) works and how to quickly and easily get started with it.

To start with, why do we need a WCF service for Telerik Reporting?  The answer is that we added a Silverlight Report viewer not too long ago, and in order to get information to a Silverlight client application you need to either use a javascript bridge through the webpage hosting the XAP, which is a slightly clunky...

If you are following the Telerik Reporting product closely you may already know that with the 2009 Q3 release we entered the Silverlight game. The industry's first native Silverlight Report Viewer allows you to display Telerik Reports in your Silverlight application while having all goodies that the Windows Forms and Web viewers offer. The new member of the report viewers' family sports report parameters, the new document map, true printing and export to all available formats, including PDF, Image (TIFF, PNG, JPEG, BMP, GIF), Microsoft Excel (XLS), Rich Text Format (RTF), HTML, CSV and the new XPS. And all this power wouldn't...

The Q3 2009 release is now in the past, but the newly introduced features are here to stay. Although the newly introduced JustCode productivity tool stirred quite a bit of excitement at PDC and in our forums, it cannot yet shade the native Silverlight support for reports created with Telerik Reporting.

Telerik Reporting Silverlight Viewer

Although there are several Silverlight viewer implementations out there, most notably for SQL Reporting Services, there is no reporting product that offers true native support for Silverlight. The Telerik Silverlight Report Viewer is designed to render Telerik Reports within Silverlight projects (see demos). The Silverlight viewer uses the same rendering...

So if you’re like me, you’re on board with Silverlight and looking to get the most out of your RIA development.  I’ve taken all the advice offered for creating Silverlight apps with WCF services- this video by Tim Heuer has been indispensible, but now we can create a Silverlight Enabled WCF service to avoid the modifications in web.config. When working on an application recently, I was somewhat confused by the error I received after deploying to my local friendly IIS server on the network:

HTTP/1.1 500 Internal Server Error

I’ve been working on a project that uses OpenAccess ORM as the persistence layer between my app and the database. Since the app is going to be used on both web and client platforms I wanted to add a services layer to serve up the data. Turns out it’s pretty easy to do. So I’ll walk you through a quick demo of how to hook OpenAccess up to WCF services and then consume the data with a RadGrid.

Set up the project structure

First, create a class library project called Data to hold the data access code. This is where you’ll use OpenAccess to...
