    Reporting: Using connectionStrings from configuration file

    We've been asked several times, what is the right way of using connection strings from the configuration file, so that Telerik Reports would work both in run time and design time. The answer can be found in this new Knowledge Base article: Using connectionStrings from configuration file It is worth mentioning that the Report and Data Source Wizards do this automatically when instructed to save the selected connection string in the config file. A working solution using the approach from the latter article can be found in our Visual Studio examples. Enjoy! ---------------- Steve...

    Medium Trust Support for Telerik Reporting

    A lot of people requested this, so we've put all our efforts into it and even managed to finish it in time for the Q2 service pack that shipped just this Friday - download it if you haven't yet. Please hold on your dismay - deploying an ASP.NET application containing Telerik Reporting on a web host that requires Medium Trust permission level is now a reality. For those of you, who do not know what that means - you probably do not need it, but if you would like to know, check the following "ASP.NET Trust Levels and Policy Files" and "Use Medium Trust in ASP.NET 2.0" documents in MSDN. There...

    Teaser: Telerik Reporting CrossTab Wizard

    Telerik Reporting Q2 2009 release (expected within a week) would come with new table/crosstab wizards. As the first one is pretty trivial i.e. you set datasource for the table and select which columns to show, we would skip detail introduction, but showing off with the crosstab wizard is something we would gladly do :) As you can see our designers have prepared some really nice images to spice it up. Now let's go to the Arrange Fields step, where we select the fields from our datasource and arrange them into Row/Column groups depending on what we're aiming for. If we skip adding fields to the...

    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...
