Only the report controls that do not intersect with each other can be correctly exported to CSV. In other cases, the resulting CSV file may have a completely broken layout.
To make sure that your report layout will be preserved in a CSV format, enable the report's DesignerOptions.ShowExportWarnings property at design time, and check to ensure there are no exclamation marks shown for intersecting controls (colored in red).
When exporting to a CSV file, XtraReports uses the protected GetTextView method of the XRControl class, which is overridden in the appropriate report control. This method returns a two-dimensional string array used for the text representation of a control. For instance, the XRLabel is represented as a simple string, the XRRichTextBox as a one-dimensional array of strings, the XRTable as a two-dimensional array of strings, and the XRPictureBox cannot be represented as a string.
Composite report documents created from multiple merged documents cannot be exported to file formats that support a continuous (table-like) layout (such as TXT or CSV).
As a workaround, use subreports to combine multiple XtraReport to a single document. Alternatively, export all your reports to CSV and TXT files separately and then join all the exported data to a single file.
You can export a report to Csv using one of the following methods with or without the CSV export options passed as parameters:
