Custom Reporting Data Filters

Overview

Custom Reporting Data Filters involve deciding which rows to include and are used in conjunction with custom data sources. Usually, a custom Report filter will apply only to a specific custom data source. This filter can filter the data returned by the data source.

The Applies method returns a boolean that specifies whether or not this Report filter should appear as a selectable filter in the Report designer. The Applies method allows a created filter to only apply to a specific data source.

 public override bool Applies(ReportDefinition definition)
{
    if (definition.UsesCustomDataSource())
    {
        foreach (ICustomReportDataSource dataSource in definition.GetCustomDataSources())
        {
            if (dataSource is SampleCustomDataSource)
            {
                return true;
            }
        }
    }
    return false;
}
