Properties panel (XAML)
The Properties panel is where you can view and modify the properties of a XAML object that is selected on the artboard or in the Objects and Timeline panel. If you modify an object directly on the artboard, the property changes will be reflected in the Properties panel.

The Properties panel includes a number editor for entering values such as degrees, pixels, percentages, and so on. For example, the RGBA color space text boxes in the preceding image are number editors. You can click an existing numerical value and type the exact value you want, or you can use the unique slider to change values by moving your pointer over the text box of the property, and then dragging when the numerical adjust pointer appears. You can also click in the text box of the property and use the Up Arrow and Down Arrow keys to adjust the value.
Some properties represent a collection of values, or represent an object with properties of its own. For example, if you add rows or columns to a Grid layout panel by clicking Edit items in this collection next to the ColumnDefinitions or RowDefinitions property, a collection editor appears in which you can add rows and columns.
You can view additional property options by clicking Advanced options next to the property that you want to modify, including custom expressions, resources, or data bindings, or to reset the property to its default value. After you set a property in the Advanced Options list, the name of the property is given a colored border so that you know what type of value is set. For example, if you set the value of a property to a System Resource, the property name will be given a green border.
