Filtering with string parameter that allows free user input
As you probably know, Telerik Reporting comes with built-in parameters and filters. Report parameters allow users to specify or control the data used in a report. They are extremely powerful when used in expressions for filtering, sorting, grouping or even directly provide a value. When used with filters you can limit the number of records in a report based on specified filter rules. If the conditions of the rules are met, the record is included in the report. Let's suppose we have a string parameter that allows free user input, wired up with a filter. This way the user has the freedom to type any word and the report would be filtered based on the parameter...

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.

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.

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...
