Methods
Arranges the content and child elements within the final allocated space, positioning text, images, and child elements.
Called by the element when constructed. Allows inheritors to build the element tree.
protected override void CreateChildElements()Overrides:
protected virtual void EnsureItemControlAdded(LayoutControlItem controlItem)Gets the the drag hint preview rectangle if an item were to be dragged at a given point.
public Rectangle GetDropHintPreviewRectangle(DraggableLayoutControlItem item, Point controlPoint, Type dragContext)The dragged item.
controlPointPointThe point in control coordinates.
dragContextTypeThe type of the dragged item.
Returns:The preview rectangle.
Gets the the drag hint preview rectangle if an item were to be dragged at a given point.
public Rectangle GetDropHintPreviewRectangle(DraggableLayoutControlItem item, Point controlPoint)The dragged item.
controlPointPointThe point in control coordinates.
Returns:The preview rectangle.
Handles dropping an element over another at the specified position.
public void HandleDrop(DraggableLayoutControlItem dropTargetElement, LayoutControlItemBase draggedElement, Point mousePosition)The drop target element.
draggedElementLayoutControlItemBaseThe dragged element.
mousePositionPointThe specified position.
Measures the desired size of the element by calculating the space needed for content, padding, and borders.
Called when the element has been successfully loaded. That includes loading of all its children as well.
protected override void OnLoaded()Overrides:
Handles property change events by invalidating the fill cache and invoking the base class property change handler.
protected override void OnPropertyChanged(RadPropertyChangedEventArgs e)Event arguments containing information about the property that changed.
