Public Interface IErrorFilteringService

Remarks

You can programmatically filter messages shown in the Error List panel:

For this, do the following:

1. Create a class that implements the IErrorFilteringService interface.
2. Use the Filter(IEnumerable<ErrorDataContract>) method to modify the collection of errors.
3. Register the custom class that implements the IErrorFilteringService interface at application startup.

The following code snippet is a service that hides all errors related to report layout:

CustomErrorFilter.cs

class CustomErrorFilter : IErrorFilteringService {
    public IEnumerable<ErrorDataContract> Filter(IEnumerable<ErrorDataContract> errors) {
        return errors.Where(e => e.ErrorSource != DevExpress.XtraReports.Diagnostics.ErrorSource.ReportLayout);
    }
}

Register the CustomErrorFilter service at application startup:

Program.cs

using DevExpress.XtraReports.Web.ReportDesigner.Services;
// ...
builder.Services.AddScoped<IErrorFilteringService, CustomErrorFilter>();
