Autofiting rows and columns (VB.Net / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\vb\VS2022\netframework\20.Reports\85.Autofit and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/vb/VS2022/netframework/Modules/20.Reports/85.Autofit
Overview
When using FlexCel, you can opt for autofit certain rows so they adjust to their content. By default, this is not done automatically for all rows since most rows do not need autofit, and so you need to use a special <#Row Height(autofit)> tag. Make sure you read Autofitting Rows and Columns in the API developer's guide for more information on autofitting.
Concepts
With default settings, autofitting rows in FlexCel will not change the autofitting status of the row. So, when you open this file in Excel, all row heights will be recalculated again, changing page breaks, but guaranteeing that all text is visible. If you prefer to keep autofitted row fixed when you open them on Excel, make the row fixed on the template or use the <#Autofit Settings> tag.
You can use an "Adjustment" parameter on the <#Row Height> and <#Autofit Settings> tags, to leave a margin for text. Remember that normally Excel text is a little wider than FlexCel's, so it might need more room. "AdjustmentFixed" is other parameter that can be used for the same thing.
You can use different types of autofit depending on your needs, and they are shown on different sheets on this demo. There are normally 2 "modes" of autofit:
The default. FlexCel autofits the rows so it can print/export fine, but leaves the rows to autofit so Excel will autofit them again when you open the file. This mode ensures text will not be "cropped" in Excel or FlexCel, but the row heights will be different in both.
"Fixed" mode. Here, FlexCel calculates the Autofit and fixes the row to that size. When you open the file in Excel rows will not change, so the page will print the same. But, as Excel normally uses more space to print the words, some words might be cropped when opening on Excel. To avoid cropping, it is recommended that you use a large Adjustment, of about 150.

' 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")>

'
' 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.
