# 4572 TDataColumn OnGetText Event Handler is Triggered at Inappropriate Times

I am loading a dataset with 16 records - each of them have a date that I want to display in my own format. In the DataSet Field on GetText event I reformat.

The StrToDate function was giving me an error - then I debugged and realized empty values were being passed to the routine - so I have a work around. But should this be happening?

I logged to a list box and found the blanks. (See attached). 7 times the event is called with blank value....

function TfrmTime.TimeDetWorkDateGetText(Sender: TObject; const Value: String): String;
var
 DT : DateTime;
begin
 ListBox1.Items.Add('>' + Value + '<');

 if value > '' then
 begin
   DT := StrToDate(value);
   result := DisplayDate(DT,1);
 end
 else
 begin
   result := value;
 end;
end;

Comments and Workarounds

The event handler was getting triggered in cases where a) the dataset was closed, and b) the dataset was empty. The workaround was as-described in the report (checking for blank value).
