        {
            IFeatureLayer actFeatLyr = (IFeatureLayer)form.axMapControl1.Map.GetLayerByName(layerName);

Use IDisplayTable when working with Joins.

Hi jamesfreddyc

                IDisplayTable dispTable = (IDisplayTable)actFeatLyr;
                ITable table = dispTable.DisplayTable;

                IRow row = table.GetRow(feature.OID);
                Debug.Print(row.get_Value(index).ToString());

Thanks you!
Perfect!
