Methods
Arranges the group link.
protected virtual void ArrangeGroupLink(GroupLinkElement linkElement, PointF beginPoint, PointF endPoint)The link element.
beginPointPointFThe begin point.
endPointPointFThe end point.
Calcs the final rect left to right bottom group link.
protected virtual void CalcFinalRectLeftToRightBottomGroupLink(GroupElement fromGroupElement, GroupElement toGroupElement, out PointF beingPoint, out PointF endPoint)From group element.
toGroupElementGroupElementTo group element.
beingPointPointFThe being point.
endPointPointFThe end point.
Calcs the final rect right to left bottom group link.
protected virtual void CalcFinalRectRightToLeftBottomGroupLink(GroupElement fromGroupElement, GroupElement toGroupElement, out PointF beingPoint, out PointF endPoint)From group element.
toGroupElementGroupElementTo group element.
beingPointPointFThe being point.
endPointPointFThe end point.
Determines whether the specified drag object [can be drag over] this instance.
public bool CanDragOver(ISupportDrag dragObject)The drag object.
Returns:true if the specified drag object [can drag over]; otherwise, false.
Called by the element when constructed. Allows inheritors to build the element tree.
protected override void CreateChildElements()Overrides:
Initializes the fields.
protected override void InitializeFields()Overrides:
Measures the space required by the RadElement Used by the layout system.
protected override SizeF MeasureOverride(SizeF availableSize)The size that is available to the RadElement. The available size can be infinity (to take the full size of the element)
Returns:The minimum size required by the element to be completely visible. Cannot be infinity.
Overrides:
In this method call to the Measure method of each child must be made.
Core logic when a drag-drop is performed over this element. Allows inheritors to provide their own implementations.
protected override void ProcessDragDrop(Point dropLocation, ISupportDrag dragObject)Overrides:
protected virtual void ProcessDragDropFieldContext(object dataContext)Determines whether the element may be treated as a drop target during drag-and-drop operation.
protected override bool ProcessDragOver(Point currentMouseLocation, ISupportDrag dragObject)Overrides:
Recreates the child elements hierarchy depending on the associated GridViewTemplate.
