    LINQ 101 Examples with Telerik OpenAccess ORM

    We all know that today LINQ is the most popular and easy way for processing data in the .NET community. In fact you can use almost all data sources you might think of: plain objects, XML or relational databases. While we have been offering an extensive LINQ support for months now, and we are continuously improving it, I don’t think it received the credit it deserves. So we decided to foster the awareness of our community towards the great LINQ support we provide with the Telerik OpenAccess ORM tool. Ok, easier said than done. What approach should we take with this one? A...

    Handling concurrent database operations with Telerik OpenAccess ORM

    What usually is of great importance to developers that use ORM tools, are issues related to concurrent updates or deletes that can potentially cause a valuable loss of data, and how the ORM framework handles the cases. Because of the state-less nature of HTTP the object-scope is re-initialized on every postback. That is an operation on its own, future blog-posts will cover some of the best practices approaches to object scope life-cycle management. The problem with stateless scenarios is that all change-tracking that the object-scope does for us in a desktop scenario is lost on every postback so there is a...

    Changing the Docking Layout Simulation – WebUI Test Studio for Silverlight Preview

    As the WebUI Test Studio for Silverlight support is going to be released in a few months I was thinking of sharing a preview via a real demo simulation. If you are not familiar with RadDocking for Silverlight, we should emphasize it is one of the most complex Silverlight components out there supporting any layout you might be interested to have. You can find it building the layout of the Bug Tracker Sample Application for example. The video below shows a simulation of a user changing the layout by pure drag and drop actions. This is exactly what one ...

    Do not filter on null

    This post might seem like a no brainer, but I've received quite a few inquiries on this matter recently, so decided to post here.  Let's say you have a parameter of Type: DateTime with AllowNull: true and we filter on a field based on the input parameter value i.e.: Expression        Operator      Value ===========   ========  ================================= =Fields.MyField        =            =Parameters.MyParam When we tick the 'null' checkbox, it basically filters the report to find the Fields with Nulls. However one might expect that it just won't filter at all with this setup. And indeed if you do not wish to filter, you should not have to. Then how do you handle "empty/blank" values in such cases and...

    Setting custom skin for the web report viewer

    I've been asked a few times by clients how to customize the web report viewer's skins, so they can better match their company identity. I would try to describe 'the process' in this post. We are trying to stay close to the approach used for the RadControls for ASP.NET AJAX, so one who has used our web controls would be pleasantly surprised to find two familiar properties in Telerik Reporting - Skin and SkinsPath. As their names suggest, the first one is used to specify the name of the skin, while the second one specifies the path where this skin can be found. Let's start with...
