How to read back files using SaveBinary tutorial in WinForms Grid Control?
Loading the WinForms GridControl with a SOAP/Binary file generated with an older version (3.3 or earlier) had a bug. Loading the SOAP has been corrected for the 4.1 version. But if you are loading a binary file, please use the attached tool - ConvertBinaryGridModelToSoap.
ConvertBinaryGridModelToSoap
ConvertBinaryGridModelToSoap fixes a problem where serialization is broken when a GridBaseStylesMap was serialized out. In that specific case full type information of the object was written out, which causes a problem when we want to read back that file after upgrading Essential Grid to a newer version.
The specific problem has been fixed for version 4.1, but reading back these faulty files is only possible if we convert them to SOAP files.
With SOAP files, Essential Grid has a workaround implemented within its LoadSoap method that fixes the problem. This allows us to read back files from older versions, even if they have full type information serialized out.
ConvertBinaryGridModelToSoap automates the process to convert one or multiple files to SOAP. In its command line, we need to specify the files we need to convert the soap and the extension that should be used for the files.
The source code for ConvertBinaryGridModelToSoap must be compiled first with the same version of Essential Grid that the file was written out with. Only then will it be able to read back in the binary serialized file.
