livebindings

I am coding a FMX Metropolis UI application and trying to assign two field values of type string to the Item.Title member of TListBox by LiveBindings technology (using expression engine). When I use a TBindList in the following way: object BindList1: TBindList Category = 'Lists' ControlComponent = ListBox1 SourceComponent = BindSourceDB1 FormatExpressions = < item ControlExpression = 'Text' SourceExpression = 'FieldByName("name1").Text + " " + Field' + 'ByName("name2").Text' end> FormatControlExpressions = <> ClearControlExpressions = <> end It assigns the 'name1 name2' string to the member

Good evening all. I'm currently trying to get to grips with livebindings in Delphi as I'd like to refresh one of my current projects (complete rework from the base for the purpose of pushing to other platforms, optimizing performance and minimizing the code). I'm working with a web API which returns JSON data. The returned JSON format for one example call would look like this; { "response": { "ips": [ { "ip": "111.222.333.444", "classification": "regular", "hits": 134, "latitude": 0.0000, "longitude": 0.0000, "zone_name": "example.com" }, { "ip": "555.666.777.888", "classification": "regular",

I have a TDataSource that is backed by a TClientDataset bound to a TStringGrid . I did this by right-clicking on the grid, selecting " Link to DB Datasource... ", and selecting the DataSource. This setup the LiveBindings for me. When I run the application, the grid only fills with 200 rows, even though there are 5000 records in the dataset. I'm unable to find any documentation regarding how to change the number of rows displayed or the proper way to allow the user to scroll through all of the data. I did find the hard coded 200 value in TBindScopeDBEnumerator.Create in the unit Data.Bind

I have been trying to make a test object that has a string property visible to the visual binding form. The component is registered with the appropriate properties. Using XE8 and Firemonkey. I can get it to show on the visual binder by selecting it using the hide show elements, however I cannot get it to bind the Foo string to a TEdit text property, the readonly (which does nothing yet) will bind to the Text Property. how do I get it show in it with default class visibility why doesn't the Foo string bind to the text property The help files are a little thin on this. I guessing I'm missing

I am trying to build something like a TLookupComboBox using LiveBindings. I have placed a normal TComboBox on a VCL form. I also have a data set with some rows that have the two fields id and text . Then I used the LiveBindings editor to create a TBindSourceDB and a TBindingsList . There is just one binding in it: object BindingsList1: TBindingsList Methods = <> OutputConverters = <> UseAppManager = True Left = 244 Top = 229 object LinkFillControlToField1: TLinkFillControlToField Category = 'Quick Bindings' Control = ComboBox1 Track = True FillDataSource = BindSourceDB1 FillValueFieldName =

It's factible or it uses some compiler technology only available in XE2 ? I just want to bind (bidirectional) a TEdit.Text property to a object function that returns a string in code (I don't need designer components or expression evaluators).. Thanks! I guess you could try Delphi sorcery library . It has quite powerful data binding solution which should work in all the modern Delphi versions. No, as far as I can tell, the LiveBindings system was implemented entirely in code with no new language features introduced to support it. Which is a bit of a shame, IMO; it could be a much simpler and
