Throbbing Items Control

Throbbing Items Control

  • Comments 8

Windows Presentation Foundation (WPF) provides a bunch of controls that are “data aware” – you can simply bind them against any data source – Xml, CLR class, etc.

I tried extending once such control - ItemsControl – which serves at the base class for controls that display a bunch of items – ListBox, TabControl, ComboBox, etc. – to add functionality that will allow N items to be displayed at a time, and then loop over the remaining items at a specified frequency. The cool part is that as far a designer is concerned, all the implementation is hidden – all the designer has to do is to use the control on the design surface of Interactive Designer, drag-n-drop data onto the control, and then worry about the presentation of data. In addition, one can specify the number of items to display at once and the refresh frequency.

Feel free to download the sample and use the control. Source available here.
