“In-situ editing” of a control property within a design surface is provided. “In-situ editing” refers to a feature that can allow a user (e.g., developer) to easily perform multi-pass configuration operations on their user interface (UI) components. This can be achieved by introducing the concept of a new editing mode or view to the integrated development environment (IDE)—(e.g., a Property Editing View (PEV)). The PEV mode can be active. In other words, the user will be presented with a mechanism of viewing and editing all properties without having to move off of the design surface. For example, editing can be performed in-place eliminating the conventional need to enter a property grid.
