hi ivo,<br />
<br />
each tfield has an onvalidate-event, where you canb place your own validation. this event is fired before the vcl tries to place the value into the current record-buffer.<br />
<br />
maybe thats a point for you to catch a possible exception before one is raised automatically.<br />
<br />
also you can use the onsettext-event of the tfield, by trying to set the value byself into the recordbuffer, and raising an exception byself, if the try failed.<br />
<br />
tell me, if you need a sample<br />

I have TTable component with persistent fields pointing to a local table (FoxPro). Further, I have form on which user enters data to my table. I need to catch exceptions which occur when end-user enters invalid value into data-aware component (or such value is assigned to a field programatically in code), for example a string value into TDBEdit that points to TDateField. Such exceptions are raised before actual posting to table, therefore they don't trigger OnPostError event.<br />

Thanks for Help, Ivo.<br />
