Hi,

I did a column MappingType.Hidden for every column beforehand.

                datatable.Columns["column1"].ColumnMapping = MappingType.Element;
                datatable.Columns["column2"].ColumnMapping = MappingType.Element;
 
2.How can I un"hide" every element?So I can access to every column again?

Thanks for the reply in advance.

DataTable Column MappingType C#

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
