Key Updates in This Release

Enhanced Enum Value Mapping for Excel Export

Excel export now supports text mapping for enumeration values through the ValueMapping attribute:

[ValueMapping(text: "Small Business Client", 0)]
[ValueMapping(text: "Tier 1", 1)]

Boolean Type Value Mapping Support

Boolean value mapping is now available for more flexible data representation:

[ValueMapping(text: "confirmed", true)]
[ValueMapping(text: "pending", false)]

Dependency Injection Support for Filters

To enable dynamic processing during import/export operations, dependency injection is now supported for filters. In ASP.NET Core applications, register dependencies in the Startup class:

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    AppDependencyResolver.Init(app.ApplicationServices);
    services.AddSingleton<IImportResultFilter, ImportResultFilterTest>();
    services.AddSingleton<IImportHeaderFilter, ImportHeaderFilterTest>();
    services.AddSingleton<IExporterHeaderFilter, TestExporterHeaderFilter1>();
}

Key points about filter dependency injection:

Injected filter types take precedence over attribute-specified filters
Injected filters operate globally across all applicable scenarios
Requires version 2.4.0-beta2 or later

Example implementation:

public class CustomExportHeaderFilter : IExporterHeaderFilter
{
    public ExporterHeaderInfo Filter(ExporterHeaderInfo headerInfo)
    {
        if (headerInfo.ExporterHeaderAttribute.IsIgnore)
        {
            headerInfo.ExporterHeaderAttribute.IsIgnore = false;
        }
        return headerInfo;
    }
}

Global Filter Disabling Capability

To disable all filters for specific import/export operations, set the IsDisableAllFilter property to true on import/export attributes.

AutoFit Row Limit Configuration

Added AutoFitMaxRows configuraton to limit automatic column sizing based on row count:

[ExcelExporter(Name = "General Export Test", AutoFitMaxRows = 5000)]

Custom Cell Width Settings

Individual column width control is now available:

[ExporterHeader(Width = 100)]
public DateTime CreationTime { get; set; }
