Data fields

Hi I have an application that writes a number of reports using Crystal Reports through a C# application and produces a pdf document as the output. I'm trying to add a new report. The data for the reports comes from a series of csv files.

I've added in the fields in the details section, however the report has misinterpreted the data types of some of the fields. It's taken an address as a number, a time field as a number and a number as a string.

How can I manually correct the field type. I can't find any option in any of the menus or property windows. I can't believe this option isn't available somewhere.

Thanks

Crystal Reports tries to keep DataSchema in Typed DataSets (.xsd files). You open XSD files and change the data types.

A Crystal report keeps Schema of data in XSD, Usually in same folder.

An approach which i know works for sure is that:
1. you can load the data from CSV to DataSet (see connectionStrings.com for connectionString for CSV files).
2. Then do export schema on dataset to get schema.
3. Update the schema to your data types in XSD file.
4. Use XSD as data definition in your reports. See http://www.c-sharpcorner.com/UploadFile/rsubhajit/CrystalReportwithDataSet03012006060655AM/CrystalReportwithDataSet.aspx[^] on how to develop reports using XSD.

Thanks

(can't find how to reply to first answer)

Are you saying that Crystal Reports internally keeps everything as xml? ie the original csv file is translated into xml? Where is the xsd file stored, I can't find one anywhere?
