Syntax
public class SchedulingDragDropBehavior : SchedulingBehaviorBase, ISchedulingDragDropBehaviorConstructors
SchedulingDragDropBehavior()
Declaration
public SchedulingDragDropBehavior()Methods
CanDrop(SchedulingDragDropState)
Gets the value specifying whether the drag operation can be completed, or not.
Declaration
protected virtual bool CanDrop(SchedulingDragDropState state)Parameters
|
SchedulingDragDropState
state
DragDropState identifying the current drag operation. |
Returns
|
System.Boolean
True when the drag operation can be finished, otherwise false. |
Remarks
This method is called on every mouse move. All properties in the DragDropState are valid.
CanStartDrag(SchedulingDragDropState)
Gets the value specifying whether the drag operation can be started, or not.
Declaration
protected virtual bool CanStartDrag(SchedulingDragDropState state)Parameters
|
SchedulingDragDropState
state
DragDropState that provides context for the current operation. |
Returns
|
System.Boolean
True when the drag operation can be started, otherwise false. |
Remarks
This method is called only when the drag operation initiated.
CreateInstanceOverride()
Creates a new instance of the SchedulingDragDropBehavior class.
Declaration
protected override PlatformIndependentFreezable CreateInstanceOverride()Returns
|
PlatformIndependentFreezable
The new SchedulingDragDropBehavior instance. |
Overrides
Drop(SchedulingDragDropState)
When overridden in a derived class completes the drop operation. This method is called only in the context of the drop target control.
Declaration
protected virtual void Drop(SchedulingDragDropState state)Parameters
|
SchedulingDragDropState
state
DragDropState that provides context for the current operation. |
Remarks
When the drag source and the drop target are the same control, this method is called before DragCompleted.
GetReorderDropPosition(Double)
Gets the drop position for the reorder based on the overlapping value.
Declaration
protected virtual DropRelativePosition GetReorderDropPosition(double overlappingValue)Parameters
|
System.Double
overlappingValue
This value indicates how much the dragged item is over the destination item. This value is between 0 and 1. |
Returns
|
DropRelativePosition
Returns DropRelativePosition enum value. |

Returns
|
System.Collections.IEnumerable

Implements
ISchedulingDragDropBehavior.DragDropCanceled(SchedulingDragDropState)
When overridden in a derived class cleans up a cancelled drag operation. This method is called only in the context of the drag source control.
Declaration
void ISchedulingDragDropBehavior.DragDropCanceled(SchedulingDragDropState state)Parameters
|
SchedulingDragDropState
state
DragDropState that provides context for the current operation. |
Implements
Remarks
This method is called only when the drag operation is cancelled by the user. If this method is called, the source's DragDropCompleted and target's Drop methods are not called.
ISchedulingDragDropBehavior.DragDropCompleted(SchedulingDragDropState, DragDropEffects)
When overridden in a derived class completes the drag operation. This method is called only in the context of the drag source control.
Declaration
void ISchedulingDragDropBehavior.DragDropCompleted(SchedulingDragDropState state, DragDropEffects dragDropEffects)Parameters
|
SchedulingDragDropState
state
DragDropState that provides context for the current operation. |
|
DragDropEffects
dragDropEffects
DragDropEffects with which the drag operation have finished. |
Implements
Remarks
When the drag source and the drop target are the same control, this method is called after Drop. This method is called only when the drag operation completed successfully. If this method is called, DragDropCanceled is not called.
