The field name can be used as an index into the control's C1Report.Fields collection.
Field names are also used to identify fields in VBScript expressions, as shown in the example below.
Duplicate and empty field names are allowed, but should be avoided if you plan to use the field names in scripts or as indexers.
_c1r.Sections.Fields["sampleField"].ForeColor = Color.Black; _c1r.Sections.Detail.OnFormat = "sampleField.ForeColor = iif(someValue < 5, vbRed, vbBlack)";
