    Binding Hierarchical RadGrid with Telerik OpenAccess ORM

    It is quite often that different customers eventually face the need to use a master-detail hierarchical representation of their data. However most customers are not aware that this is extremely easily achievable using Telerik OpenAccess ORM together with our RadGrid. Furthermore it is achieved without writing ANY code in the code behind file of your project. Now let’s get to the job! What will be needed is just one RadGrid and two OpenAccessDataSource controls. The two data source controls will be used to query data from the master and detail tables. In our case we used the Company and Employee tables(one company has many...

    Impressions from Basta Germany Developer Conference

    Just coming back from Mainz, Germany where Basta 2009 took place this week. It was a great conference where Telerik provided Silver Sponsorship and very nice lanyards to the approximately 700 attendees. Stephen Forte enjoyed speaking at a German conference for the first time. Check out his post about how to write a WCF service and then call it from Silverlight asynchronously. Telerik OpenAccess ORM expert Jan Blessenohl also gave a presentation on ORM and RIA Services. You can see a photo from our booth on the evening before the show - as usual Telerik was early and well prepared. Many professional developers stopped...

    Altering OQL queries to generate different JOIN clauses in SQL

    As most of you probably know, OQL was the main object-oriented query language that was supported by Telerik OpenAcess ORM before Linq was introduced in .NET. Even though Linq is now the de facto standard for querying data, support for OQL is still there and I would state that it still is pretty convenient to use in some scenarios. We will use this post to share some tips on querying data using the Object Query Language. Consider the following query: IQueryResult projection = scope.GetOqlQuery("SELECT pr.ProductName, cat.CategoryName " + "FROM CategoryExtent AS cat,cat.Products AS pr").Execute();  This query makes...

    Sorting, Filtering, Grouping and Aggregating on all CPU cores using RadGridView for WPF and PLINQ

    As some of you may already know the Q2 release of RadGridView for WPF ships with a brand new “data engine” entirely based on LINQ. This means that all data operations including sorting, filtering, grouping, aggregating and paging will be pushed down to the IQueryProvider when RadGridView is bound to an IQueryable. For example if you are using LinqToSql, LinqToEntities or OpenAccess ORM all gird operations are executed on the SQL server using the magic of LINQ providers. Staying on the cutting edge I decide to try out PLINQ (Parallel LINQ) and enable RadGridView to execute its data operations on all available CPU cores. PLINQ...

    O# or The Fall Conference Speaking Schedule

    digg_url = "http://www.stephenforte.net/PermaLink,guid,8d9a457e-c203-43d0-bedd-27336578c997.aspx";digg_title = "O# or The Fall Conference Speaking Schedule";digg_bgcolor = "#FFFFFF";digg_skin = "normal";digg_url = undefined;digg_title = undefined;digg_bgcolor = undefined;digg_skin = undefined; Every fall, the kids go back to school, the weather gets cooler, Munich kicks off its annual Oktoberfest festival, and the fall conference season heats up. It seems that I always miss Oktoberfest. I had friends who lived in Munich earlier this decade and each year my trips to Mt. Everest got in the way. Now that Telerik has a Munich office, I got to go to Oktoberfest (O#) with geeks. I can see the eyes rolling by the non-technical readers of this blog (basically my Mom is the only non-technical person who reads this blog), however, geeks can drink a lot, judging by how I had to...

    RadChart for SL/WPF: Data grouping and aggregation

    Howdy folks! The RadControls for XAML Q3 Beta1 is out and it features an updated version of the RadChart control. We receive dozens of feature requests every day and one of the more substantial ones is the ability to analyze data with RadChart. The feature I will describe today is a great step in that direction. I’m talking of course about data grouping and aggregation.   Just like grouping and aggregate functions are one of the major features of our GridView control they can be used with the charts as well (if you have the beta). Basically the feature allows you to group business...

    Create a SQL Azure CRUD Application with Telerik OpenAccess and the WCF Wizard

    digg_url = "http://www.stephenforte.net/PermaLink,guid,a7d16ce5-33d4-475b-bb5a-32d38c2a99b4.aspx";digg_title = "Create a SQL Azure CRUD Application with Telerik OpenAccess and the WCF Wizard";digg_bgcolor = "#FFFFFF";digg_skin = "normal";digg_url = undefined;digg_title = undefined;digg_bgcolor = undefined;digg_skin = undefined; Over the past few weeks I have showed how to use Telerik OpenAccess with the WCF Wizard. I think that this wizard is a crucial piece of technology since I hate to write plumbing code myself, it takes me too long and I usually make mistakes. I wish that SQL Azure would provide RESTful and WCF services wrapped around your database tables and views with just a check box in the Azure management page. But alas, I can dream. Until that day arrives, you will have to code the services yourself. So I decided to do it with OpenAccess and WCF (and of course the Wizard.) First you...
