    When you query a picture for the first time, it uploads it and save to Assets, the next time it will no longer upload a picture. And your fgimage always geting pic from Assets.

    Hi All, now my demo works better, thanks Knsg12. However i've seen that TfgAssetsManager.Current.AddBitmapFromUrlAsync take a lot of time ( 20 - 30 seconds ) to download the thumbnail from 'https://via.placeholder.com/150/92c952'. I've tried also to update your demo AsyncBitmapAssetDemo and i've replaced your sample url with mine. The first execution take 20 second, the nexts less than 1 second. How could be possibile ? Many thanks guys for your support.

    Hi Knsg12, you are right... AlbumId is not unique... excuse me. I check better if now it is solved. Thanks a lot, Luke.

    if not TfgAssetsManager.Current.Contains(Item.FalbumId) then TfgAssetsManager.Current.AddBitmapFromUrlAsync(Item.FalbumId, Item.FthumbnailUrl); AItem.GetControlByLookupName<TfgImage>('ImgAlbum').ImageName := Item.FalbumId; Try it! I think Item.FalbumId not uniq field for records, it needs to be replaced by Item.Id.

    Hi All, i'm testing tfgCollectionView with this rest resource : http://jsonplaceholder.typicode.com/photos In this test my CollectionView Style has 1 fgImage and 1 fgLabel. I get the RestResouce with a TRESTRequest.ExecuteAsync and it works perfectly. When i've the ExecuteAsync CallBack i parse the JSON output string and i fill my Photos collection (TList). I do this step with a separate Task because i've 5000 items ( more or less). When i link data to the CollectionView i call fgCollectionViewGetItemCount and fgCollectionView1BindItem. If i bind only the fgLabel all works perfectly. My problem is link the tfgImage to the thumbnail. I post my code: procedure TFramePhoto.fgCollectionView1BindItem(Sender: TObject;const AIndex: Integer; const AStyle: string; const AItem: TfgItemWrapper); VAR Item:TPhotoData; begin TRY Item:=RestPhotos.Items[AIndex]; AItem.GetControlByLookupName<TfgLabel>('LblTitle').Text := Item.Ftitle; TfgAssetsManager.Current.AddBitmapFromUrlAsync(Item.FalbumId, Item.FthumbnailUrl, procedure (const AResultCode: Integer; const AResultMessage: string) begin AItem.GetControlByLookupName<TfgImage>('ImgAlbum').ImageName := Item.FalbumId; end); EXCEPT ON E:EXCEPTION DO FGX.Log.TfgLog.Log(TfgLogLevel.Debug,'fgCollectionView1BindItem ' + e.Message); END; end; Actually i'm saving the images in assets but i think it is a bad idea... Can you suggest a best practice for this scenario ? Thanks a lot guys, Best Regards.

    Ярослав, пожалуйста добавьте в исходники Assets, раньше они были, потом исчезли, для справочной информации нужны, правда правда. Спасибо

    Hello, I have tried this source code before, but failed to apply it to FGX. in this section I have not found the code on FGX. QRCodeBitmap.Canvas.Pixels[Column, Row] := clBlack; and how to repaint tfgpaintbox. Thanks you

    Hello Luke, TfgSearchEdit doesn't depend on other controls. It just provide text input field with autocomplete functionality. And it supports 2 ways for getting autocomplete values: Static. Manual setting of values via Suggestions property. For small values list. Dynamic. You fill suggestions list in OnChanging event. The CollectionView filtering method is fully provided to you. For example: You can filter your collection view model data (related TList, model, DAO and etc) and invoke ReloadItems. Also if you provide unique item's id via OnGetItemID, collection view will animate refreshing items. So user will see which items are disappeared. Thank you

    Hi All, I'm trying to use a tfgSearchEdit with a tfgCollectionView. I'm searching the better way to set the focus to the CollectionViewitem that match my search value. There is a demo that explain this management ? I've seen that i can fill the SearchEdit.Suggestions with the CollectionViewItems field otherwise i can do a binarysearch in the Tlist<> that is linked to the CollectionView but i've to sort the list. Can you suggest a best practise for that ? Thanks a lot, Luca.

    fglistMenu component has an event OnTapItem. procedure TFormMain.fgListMenu1TapItem(Sender: TObject; const AItem: TfgListMenuItem); AItem is what you need.
  22. Luke
    Hi All, i've tryied to manage the event fgListMenuItemOnTap as written below and i've seen that the Sender is not a fgListMenuItem object but fgListMenu. procedure TFormMain.fgListMenu1Items0Tap(Sender: TObject); begin fgLabel3.Text := Sender.ToString(); end; In this way i'm not able to understand witch item i've pressed so i've to manage each onItemTap with a specific event. Is it normal or i'm doing a mistake ? Thanks a lot, Luca.

    Hello, I need a component that can generate QRCode. logically it can be generated on the server, then the application downloads as an asset. but it will be easier if FGX can generate it. thanks you

    Hi all, just for sample i'm trying to put a square in the form center, and a circle in the square center. I've placed a layout with FlexGrow=1 so it will take all the form space and AlignmentChildren.JustifyContent=Center. Into the layout i've placed the square with PositionMode=relative. Now if i try to put the circle i can't use relative position but only absolute and i've to place the circle in the center without any support. How i can solve ? Thanks a lot, Best Regards.
