Hi Georgi,

you can look at the VCL in dbgrids.pas and db.pas and will find, that on
leaving the DBgrid column containing the TDateTimeField there will be called
a procedure called TField.SetEditText. This calls the OnSetText procedure if
assigned, or the standard SetText procedure which again will call the
TDateTimeField.SetAsString method. Here are the calls to StrToDate,
STrToTime or StrToDateTime depending on the DataType property. And here
arises the exception.

So, you can place your own checks in the OnSetText event instead of in the
OnValidate event.
