What is "designbox"

Designbox for Visual Studio is a UI design productivity tool for Microsoft Visual Studio. It adds a new toolbox window that can associate initial property values with control items. It then applies these initial values to the control each time that control is drag and dropped onto the Form Designer. Designbox also includes the Design Gallery window that is used to apply pre-defined designs to existing controls.

Designbox currently supports .NET Windows Forms applications and works with all the major WinForms control suites from third-party vendors such as ComponentOne, Developer Express, Infragistics, Telerik and Syncfusion.
