    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...

    WebUI Test Studio and Sitefinity

    The folks from Telerik Sitefinity team just blogged about testing the Sitefinity modules with WebUI Test Studio. There are several important facts I’d like to point you to: - You can automate the testing of all the elements on the page in any ASP.NET Web application with WebUI Test Studio. Sitefinity CMS is an excellent example as its modules often contain quite complex pages. - Although we often highlight the RadControls Translators we add as the third component of the test studio, the product is not limited to testing of RadControls-based applications at all. For example such small but ...
