Bidirectional reports (C# / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\csharp\VS2022\netframework\20.Reports\42.Bidirectional Reports and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/csharp/VS2022/netframework/Modules/20.Reports/42.Bidirectional Reports
Overview
In this example we will create a report that grows both horizontally and vertically.
Concepts
Normally ranges in FlexCel reports can't intercept. But there is an exception: If you define a range in the shape of a cross, FlexCel will do a bidirectional report.
In Bidirectional reports the row range acts as the master, and the column range as the detail. You can have more than one column range for the same row, but not more than one row range for the same column.
In this example we have two different column reports using the same row report. In the first column we show which employees have orders for a given customer, and in the second we show the orders for that customer.
Those two columns are conceptually different: In the first we use a column and row dataset which are not related. This will create a square with all the records of the column dataset for the column, and all the records of the row dataset for the rows. In the second column, the column dataset (orders) is related to the row dataset (customers). So the number of columns will be different for each row, depending in how many orders that customer has. FlexCel will insert as many columns as the maximum numbers of orders for any customer.
You can look at the User Defined Functions example for another demo on how bidirectional reports work.

// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
//
[assembly: AssemblyTitle("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("(c) 2002 - 2024 TMS Software")]

//
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the '*' as shown below:
[assembly: AssemblyVersion("7.21.0.0")]
//
// In order to sign your assembly you must specify a key to use. Refer to the
// Microsoft .NET Framework documentation for more information on assembly signing.
//
// Use the attributes below to control which key is used for signing.
//
// Notes:
// (*) If no key is specified, the assembly is not signed.
// (*) KeyName refers to a key that has been installed in the Crypto Service
// Provider (CSP) on your machine. KeyFile refers to a file which contains
// a key.
// (*) If the KeyFile and the KeyName values are both specified, the
// following processing occurs:
// (1) If the KeyName can be found in the CSP, that key is used.
// (2) If the KeyName does not exist and the KeyFile does exist, the key
// in the KeyFile is installed into the CSP and used.
// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
// When specifying the KeyFile, the location of the KeyFile should be
// relative to the project output directory which is
// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
// located in the project directory, you would specify the AssemblyKeyFile
// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
// (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
// documentation for more information on this.
