Occurs when the value of the IsEnabled property on this element changes.

Occurs when the value of the IsHitTestVisible dependency property changes on this element. Occurs when the value of the IsKeyboardFocused property changes on this element. Occurs when the value of the IsKeyboardFocusWithin property changes on this element.

Occurs when the value of the IsMouseCaptured property changes on this element. Occurs when the value of the IsMouseDirectlyOver property changes on this element. Occurs when the value of the IsStylusCaptured property changes on this element.

Occurs when the value of the IsStylusCaptureWithin property changes on this element. Occurs when the value of the IsStylusDirectlyOver property changes on this element. Occurs when the value of the IsVisible property changes on this element.

Occurs when the layout of the various visual elements associated with the current Dispatcher changes. Occurs when a manipulation and inertia on the UIElement object is complete.

Occurs when the input device loses contact with the UIElement object during a manipulation and inertia begins. Occurs when an input device begins a manipulation on the UIElement object. Occurs when there is a change in the keyboard or mouse button state during a drag-and-drop operation.

Occurs when the stylus moves while over the element. The stylus must move while being detected by the digitizer to raise this event, otherwise, PreviewStylusInAirMove is raised instead. Occurs when the cursor is requested to display. This event is raised on an element each time that the mouse pointer moves to a new location, which means the cursor object might need to be changed based on its new position. Occurs when BringIntoView Rect is called on this element.

Occurs when either the ActualHeight or the ActualWidth properties change value on this element. Occurs when the stylus moves over this element. The stylus must move while on the digitizer to raise this event. Otherwise, StylusInAirMove is raised instead.

Duracell myGrid puzzles me. It's a charging system consisting of a base pad where devices with special contact pads called Power Sleeve or Power Clip are placed for charging. The base pad surface is covered in parallel metal stripes connected to the power source such that even pads are positive terminals and odd pads are negative terminals.

The device to charge is equipped with a matching pad that has four small edge contacts projecting downwards and aligned in star pattern such that however the device is positioned on the pad there exist at least two contacts that connect to different stripes on the base pad.

This is guaranteed by following the right proportions between the stripes widths and the distances between the contacts on the device pad. So however the device is positioned on the pad it gets connected to both a positive and a negative base terminal and receives power for charging.

The latter is what puzzles me. How is such contact pad the one of the device designed that it allows up to three contacts to be connected to the same terminal and no matter which fourth contact is connected to the opposite terminal the device is being powered correctly regardless of how the device is positioned on the base pad? I have not seen the circuitry used or even seen a Mygrid device but it almost certainly works by having two diodes from each Mygrid contact point to the internal power circuit in the device being charged.

One diode per contact connects with its Cathode connected to the Mygrid contact and its Anode to accessory "-ve" connection ie the diode "arrow" points from accessory towards the Mygrid device. This diode conducts when a Mygrid -ve terminal is encountered.
