    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...

    Connecting the Dots: ADO.NET Data Services and Telerik Reporting

    ADO.NET Data Services (formerly Astoria) is one of the new technologies released as part of v3.5 SP1 of the .NET Framework. If you haven’t tried this new addition to the framework, I highly suggest you give it a spin. It’s very cool and allows you to quickly and easily set up RESTful WCF services with which your application can interact with the database. If you’re interested in learning more, MSDN has several great resources to help you get started. One of the cool things about Telerik is that the developers are always mindful of building products that can be easily integrated with existing and future...

    Telerik Reporting: Connecting to Stored Procedures

    I’ve blogged in the past about the many ways you can connect your reports to data. Because the developers who build Telerik’s Reporting Tool wanted to make it as flexible as possible, they designed it to have the ability to bind to any object that implements one of the four supported interfaces: IEnumerable, IListSource, ITypedList, and IDbDataAdapter. What does this mean for you? No matter where your data comes from – plain SQL queries, stored procedures, web services, etc – you can bind it to a Telerik report. Okay, I realize that showing an example is much more effective than just talking...
