public event EventHandler<C1DragPreviewEventArgs> DragPreview
Event Data
The event handler receives an argument of type C1DragPreviewEventArgs containing data related to this event. The following C1DragPreviewEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the recognition of this gesture is canceled. |
| CaptureElementOnPointerPressed | Gets or sets a value indicating whether the element will be captured in pointer pressed event (MouseLeftButtonDown in SL and WPF and PointerPressed in WINUI) or in the first pointer move event (MouseMove in SL and WPF and PointerMoved in WINUI).Capturing the element on mouse down will cause Click, DoubleClick and MouseLeftButtonUp events not to be fired in sub-elements (nested elements in the visual tree), whereas capturing the element on the first mouse move can make it difficult for final users to drag small elements quickly. |
