Parameters inside expressions (C# / netframework)

Note

This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\csharp\VS2022\netframework\20.Reports\50.Expression Parameters and also at https:​//​github.​com/​tmssoftware/​TMS-​FlexCel.​NET-​demos/​tree/​master/​csharp/​VS2022/​netframework/​Modules/​20.​Reports/​50.​Expression Parameters

Overview

In FlexCel it is possible to create Expressions that include parameters.

Concepts

  • How to create report Expressions using parameters.

  • How to apply an Expression Format to a formula. You can't directly write a formula like: =a1+1<#format cell(blue)> because of course Excel will not recognize it as a valid formula.

    But you can use the <#format range> tag to format the formula. On this example, formula is on column "D" and the formatting tag for the formula is on column "E"

AssemblyInfo.cs

using System.Reflection;
using System.Runtime.CompilerServices;

//
// 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 - 2025 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("7.25.0.0")]

//
// 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.
