![]() Usually kbmMW’s SmartBinding is figuring out automatically if something has changed, and it could do so also when operating on TImage instances. The first line is easy to understand… it loads a PNG file based image into the TImage instance. Binding.Bind(dataset,'Graphic',Image1,'Picture',) procedure TForm1.btnLoadBitmapClick(Sender: TObject) But there is a catch, I will explain in a moment.įirst lets define the binding and make a button that loads a new image into the TImage from a file. In Firemonkey, the same is possible, except you bind to the property named Bitmap of the FMX TImageīut what if we want to update the contents of the TImage, and have that reflected back in the dataset? Two way binding is the way. Then we bind a couple of fields to some edit boxes, and the Graphic field to the Image1.Picture property.Īnd clicking the buttons will update the form according to which record is current in the dataset. Mt.LoadFromFileViaFormat('biolife.csv',csv) īnd:=Binding.Bind(dataset,'Category',Edit5,'Text',) īinding.Bind(dataset,'Species Name',Edit6,'Text',) īinding.Bind(dataset,'Graphic',Image1,'Picture') īasically what we do, is load a memory table with a CSV variant of biolife which also contains a bitmap. In the ‘Prepare dataset’ buttons event handler we have this code: procedure TForm1.Button8Click(Sender: TObject) Binding graphics to TImage and a binding catchīinding from for example a dataset to a TImage is very easy with kbmMW, in both VCL and FMX mode. This post focus on how next kbmMW release will support binding to TImage and TListView (both the VCL and the Firemonkey variant of them). In the previous SmartBinding posts, I have shown how to bind to many different types of controls and data sources. ![]()
