Balanced columns (VB.Net / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\vb\VS2022\netframework\20.Reports\57.Balanced Columns and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/vb/VS2022/netframework/Modules/20.Reports/57.Balanced Columns
Overview
The FlexCel reporting engine will automatically balance the ranges that are inside a master range so the master range will stay in place. You can use this feature for creating master detail reports with balanced columns inside (where the master will grow to cover the longest column), or use a fake "master" report to ensure the columns inside the report have the same number of rows.
Concepts
How to create a master detail report with detail columns, and where the master grows with the biggest of the columns. In columns where the number is less, the last cell of the column will be copied to fill the missing rows, so all columns have the same height.
How to use Fixed N Bands to avoid having empty rows at the end of each master record.
How to use the "ROWS" function in the config sheet (see Creating empty datasets with N rows) to create a database with a single row, that you can use as a master from the main report, and so ensure balanced columns.
For more information in balanced columns please take a look at the section Fixed N Bands in the Reports designer's guide.

' 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 - 2014 TMS Software")>
<Assembly: AssemblyTrademark("")>
<Assembly: AssemblyCulture("")>
'
' 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("6.2.1.0")>
'
' 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.
