I not sure if this are a bug, I save some new data (aprox 30000 bytes, with a base64 string from a memorystream of a devexpress grid savelayout method), edit this with some value and the "truncate" error happen :/I will try with a text field and a fixed varchar value (something like 50000)Additionally to this when I used the method "SetDebugOn" on my datasource with the 2nd parameter on true (overwritefile) If the file not exist it give me an error. (I not sure if the method have to create the file if it not exist)Thanks for the great support.-Fabian
