Answering my own question:,To dynamically format autogenerated field, use this:

DirectCast(column, AutoGeneratedDataField).DataFormatString = "{0:P}"

Hi Denis,

I am also having this problem.

The link you provided results in 404 error, while the sample I downloaded does *not* show how to use FormatFieldMethod function.

Specifically all samples from Infragistics show how to return 'hello', but do not show how to properly pass values.

Could you please post a code sample of how to use  FormatFieldMethod function.

Thank you,

Helen.

thank you, this helped.
