Custom format

Xavi

Is there a way to add a "custom format" in the "Select Format" window?

I need to use calendars that do not exist in Windows and I would need to add custom formats as "Solar Calendar", "Serial Calendar", etc..

Thanks

Hello,

It's not possible without modifying the source code of FastReport.Net.

Can you let provide me with a basic guide? Which function or source file do I need to modify mainly?

Thank you

It's quite complex task:
- you have to create own format based on FastReport.Format.FormatBase class;
- register it in the AssemblyInitializer class (see AssemblyInitializer.cs file);
- modify the TypeConverters\FormatConverter.cs file (ConvertFrom method);
- modify the FastReport.Forms.FormatEditorForm class to add the format ui editor (most complex task).

This solution works fine but it is very dependent of your updates. I would ask you as suggestion, if it is possible, to add something like IFormatProvider / ICustomFormatter in the FR Net project.
It would be nice that we can register a formater from our application.
For example, I would need to add in "Select Format / Date" an industrial calendar (a date calendar used in many industries), or Solar Calendar used by some users in the Iran and not supported by .Net.
Also, some customers want dates like 10AUG08.

It is not necessary that the user enters parameters for the format. I am asking to be able to register custom closed formats, without user parameters.

Another option would be to offer a delegate or event from the source to format the text to be printed out.

Thank you

Hello,

It's hard enough to make existing format system extendable. I will try to do this in the next major version.
