Using TDataSet.FindKey you can locate records. When it results in True the datasets cursor will be positioned on the found record. When it results in False the cursor is not moved. This results in the record data prior to FindKey being issued being displayed in data aware components.
How can I code the result of FindKey to return an empty record?
if Not tblSomeTable.FindKey([SomeSearchData]) then
begin
< code to return empty or move data cursor to neutral position >
end;
Thanks, John
