![]() The new control resembles the classic TDBCtrlGrid control - there is a panel for controls, you put controls on it and have virtual items created at run time. Beside calculating and displaying only the items that fit on screen, the list caches the content of the items using in-memory bitmaps. ![]() Being totally virtual, the list can handle thousands and even millions of items, offering extremely fast scrolling. The new control allows the developer to define the content by designing one of the elements of the list using graphical controls (that is, TGraphicControl descendants) and provide data to the control to display individual elements, without creating all of the controls for all of the elements in the list, but only those needed to display the data. ![]() This list represents a single selection list and all items are visually of the same height and width. The idea behind this control is to offer a new modern looking VCL control offering custom UI configuration and a high performance control, which can be used with very long lists. New VCL TControlList controlĮmbarcadero is introducing in the VCL library a new flexible and virtualized list control. This is some pre-release information (or beta blogging) on one specific area, new VCL controls. The release of RAD Studio 10.4.2 is getting closer and you can join our preview webinar tomorrow, see. Warning: This blog post covers an unreleased product, which is subject to change until GA.
