TDataSet-based data controllers - Extend the Filter.OnFormatFilterTextValue event with a parameter identifying the filter condition whose value is to be formatted

The Filter.OnFormatFilterTextValue event has been extended with the AItem parameter, which provides access to the filter condition whose value (passed as the AValue event parameter) is to be formatted.

Dear Dennis,
Sorry, we haven't yet implemented this feature … just because you are the only person asking for it. Perhaps, we will implement it, but it is preceded by other items which have higher priority in our TO-DO queue. For now, we have a very long TO-DO list and all our developers are concentrated on such tasks as the Ribbon control (in particular, galleries - CS43976 ("Ribbon - Add a bar item, which represents an in-Ribbon gallery")) and our new skinning UI. These tasks have the highest priority in our development plans and, in fact, they were planned a long time ago.
We do understand that this functionality is critical for your development, but we cannot give you any time frames for when it may be available. We have a strict policy of not announcing any specific features for any product in R&D prior to its release or imminent release. The reason for this policy is that we do not want our customers to base their development on some new functionality and components we're planning on delivering and then have big problems if for some reason we fail to do so. That's why we don't disclose release dates and why, in general, we don't describe in detail the features in each version until the release date.
Please keep tracking this report to learn our progress about this feature.

A possible workaround from report DQ10623 ("SQL 2003 Date Time format"):

Code
*I modified your code, which I hate doing, but had no choice. The mod is as follows:*  

```delphi  

cxDBData.pas  

type  
 TcxDBDataFilterFormatFilterItemEvent = procedure(Sender: TcxFilterCriteriaItem;  
   const AValue: Variant; var ADisplayValue: string) of object;  
....  
 TcxDBDataFilterCriteria = class(TcxDataFilterCriteria)  
 private  
   FOnFormatFilterItem: TcxDBDataFilterFormatFilterItemEvent;  
 published  
   property OnFormatFilterItem: TcxDBDataFilterFormatFilterItemEvent read FOnFormatFilterItem write FOnFormatFilterItem;  
....  
procedure TcxDBDataFilterCriteria.FormatFilterTextValue(AItem: TcxFilterCriteriaItem;  
 const AValue: Variant; var ADisplayValue: string);  
begin  
 if Assigned(FOnFormatFilterTextValue) then  
   FOnFormatFilterTextValue(Self, AValue, ADisplayValue);  
 if Assigned(FOnFormatFilterItem) then  
   FOnFormatFilterItem(AItem,AValue,ADisplayValue);  
end;  

```  

*I am now able to implement a much more elegant solution as follow:*  

```delphi  

procedure TMainForm.OnFormatFilterItem(Sender: TcxFilterCriteriaItem; const AValue: Variant; var ADisplayValue: string);  
var  
   vColumn: TcxGridDBColumn;  
begin  
   vColumn := TcxGridDBColumn(Sender.ItemLink);  
   case vColumn.DataBinding.Field.DataType of  
   ftDate : ADisplayValue := 'DATE '+ADisplayValue;  
   ftTime : ADisplayValue := 'TIME '''+TimeToStr(AValue)+'''';  
   ftGuid : ADisplayValue := 'GUID '+ADisplayValue;  
   end;  
end;  
```  
  
*As you can see I have added a new published event handler, that implements TcxFilterCriteriaItem instead of the near useless TcxDBDataFilterCriteria object as per the OnFilterFormatFilterTextValue method.*
