Tile Control Tutorial. Step 3: Add a Simple Functionality to a Tile Item

• Dec 28, 2020

In this step, you start with the configured and decorated tiles in the TdxTileControl component.

Handling the tile’s OnClick event is the simplest way of adding functionality to it.

To make the OpenDevExpressURL tile open the official DevExpress site in the default system browser, first add the ShellAPI unit to the ‘uses’ clause (or the ShellAPI.hpp header to the MainForm.h file in C++Builder). Then, add the following line to the empty OpenDevExpressURLClick event handler procedure:

Delphi

ShellExecute(0, 'open', 'http://www.devexpress.com', nil, nil, SW_SHOW);

C++

ShellExecute(0, L"open", L"http://www.devexpress.com", NULL, NULL, SW_SHOW);

Then, compile and run the demo application. Clicking the OpenDevExpressURL tile now opens the specified URL by using the default system web browser.

Additionally, you can handle the OnClick or OnActivateDetail event of the LoanCalculator and SystemInformation tiles. However, adding the actual functionality to these tiles is outside the scope of these Tutorial topics.

The next step describes how to add dynamically changing frames to the HouseDetailPage tile from a dataset.
