In FastReport 2019.4 added the ability to subscribe to PreviewControl.OnPrint and PreviewControl.OnExport events, which are called directly when the corresponding buttons are pressed. When viewing a report, a viewer is called with a toolbar that has elements such as a print button and a drop-down list with report exports. Selecting any item in the list will trigger the OnExport event, and pressing the Print button will trigger OnPrint. Let's take an example and see how we can use these events in practice. You can use the standard handler for these events, which is created for the visual component of PreviewControl:   In this case you just add the necessary actions to the handler. But if you add the PreviewControl component in the application code, you will have to sign your own handler for the eve ...

Long time ago an interesting functionality appeared in Microsoft SQL Server 2005- window functions. These functions allow you to perform calculations in a given range of lines within a Select clause. For those who have not encountered these functions, the question arises - “What does window means?”. A window means a row set within which calculations are performed. The window function allows you to break the entire data set into such windows. Of course, all that window functions can do is also possible without them. However, window functions have a great advantage over regular aggregate functions: there is no need to group the data set for calculations, which allows you to save all the rows in the set with their unique identifiers. At the same time, the results of the work of window functions are simply added to the resulting sample as another field. The main advantage of using window functions over regular aggregate functions is as follows: window functio ...

In FastReport .NET 2015.1 we have released an Online Report Designer.

The full-featured version of the Online Report Designer is available in the Professional edition of FastReport .NET. A demo version is available in Trial edition. You can download it from our site for free. The evaluation version cannot save reports back in the server. At the moment Online Report Designer works together with the object WebReport. Also you can use the Designer in ASP.NET MVC. Online Designer allows you to edit the appearance of reports, modify the properties of objects, add new objects etc. Online Designer can change the script of the report and event handlers of the report, but by default for security reasons this option is disabled. This feature can be enabled in the properties of the object WebRe ...

Today I would like to talk about the way the foreach loop works inside. We all know that a foreach loop is - a loop that iterates through all the elements of the collection. Its greatest advantage in the ease of use - we do not need to worry about how many elements in the collection. However, many do not know that this is just syntactic “sugar”, which facilitates the work of the programmer. Therefore, we simply have to know in what the resulting compiler will convert. The foreach loop works differently, depending on the collection you want to sort through. 1)      If it has to deal with the banal array, we can always know its length. Therefore, foreach will eventually be converted to a for loop. For example: ...
