These steps are useful to link with the selected value if we are managing several fields of a database. Note: These last steps are not mandatory for this tutorial since there is only one field in BindSourceDB1. Click the Finish button to close the wizard.Select Link a control with a field binding task. Set the Command Text property to select ShopItem from Item.Īt this point, TBindSourceDB and TFDQuery components were added to your form.Select Create a data source binding task.Select View > LiveBindings Designer and the LiveBindings Designer opens.This tutorial uses the LiveBindings Wizard to add the LiveBindings components ( TBindSourceDB, TBindingsList), and the TFDQuery component. Set the Align property to Client, so that the ListView component uses the entire form.Drop a TListView component on the form and set the following properties in the Object Inspector:.Expand the TTextSettings node and set the HorzAlign property to Center.Drop a TLabel on the ToolBar component and set the following properties in the Object Inspector:.Set the StyleLookup to deletetoolbutton.Drop a TButton on the ToolBar component and set the following properties in the Object Inspector:.To set up a ListView component and other UI elements, use the following steps: This tutorial uses one TListView component as the UI element. Visible UI components are loaded on the designer Right click the FDQuer圜reateTable and choose Execute.Set the Name property to FDQuer圜reateTable.ĬREATE TABLE IF NOT EXISTS Item (ShopItem TEXT NOT NULL).In the Object Inspector, set the following properties of TFDQuery:.On the Tool Palette, double-click the TFDQuery component.Set the LoginPrompt property to False, so that the user is not prompted for a login.In the Object Inspector, set the following properties of TFDConnection:.Click OK to close the Connection Editor.Click the Test button to test the connection.Set the LockingMode parameter to normal.(To display Employees.s3db or other *.s3db files in the Open dialog, set the All Files (*.*) option.) Note: You can set the above Database parameter even if shoplist.s3db does not exist, RAD Studio creates it automatically. In the FireDAC Connection Editor, set the following parameters of the TFDConnection:Ĭ:\Users\Public\Documents\Embarcadero\Studio\22.0\Samples\Data\shoplist.s3db (location of the database) and click Open in the File Open dialog box.Right click the TFDConnection component and choose Connection Editor.On the Tool Palette, double-click the TFDConnection component.Therefore, you need to develop applications using middle-tier technologies such as DataSnap REST to connect to these database products from a mobile device.įor C++: File > New > Multi-Device Application - C++Builder > Blank Application On Windows platforms, the client library is provided as a DLL to connect to. For other databases, such as Oracle, you need to have at least a client library.These database products can run on iOS and Android devices. For the mobile platforms, FireDAC supports InterBase ToGo as well as SQLite.With its powerful common architecture, FireDAC enables native high-speed direct access from Delphi to InterBase, SQLite, MySQL, SQL Server, Oracle, PostgreSQL, IBM DB2, SQL Anywhere, Access, Firebird, Informix, and more. This tutorial describes the basic steps to use SQLite as a local data storage on your mobile device through the FireDAC framework.įireDAC is a unique set of Universal Data Access Components for developing cross-platform database applications for Delphi and C++Builder. Mobile Tutorial: Using LiveBindings to Populate a ListView (iOS and Android).11 Running Your Application on a Simulator or on a Mobile Deviceīefore starting this tutorial, you should read and perform the following tutorial session:.10.1 Specifying the Location of the SQLite Database on the Mobile Device.10 Modifying Your Code to Connect to a Local Database File on mobile.9.1 Add and Configure Your Database File in the Deployment Manager.9 Setting Up Your Database Deployment for mobile.8 Preparing Your Application for Run Time.7 Creating the Event Handler for the Delete Button to Remove an Entry from the List.6 Creating the Event Handler for the Add Button to Add an Entry to the List.5 Creating the Event Handler to Make the Delete Button Visible When the User Selects an Item from the List.4.3 Displaying ShopItem in the ListView.2 Creating the Database using FireDAC framework.1 Using FireDAC to Connect to the Database.
