Methods
AnalyzeQueue(List<GridViewEvent>)
Allows a listener to examine events queue and optionally to remove/add events.
Declaration
public bool AnalyzeQueue(List<GridViewEvent> events)Parameters
events
List<GridViewEvent>
Returns
True if the listener has actually modified the queue, false otherwise.
Implements
ArrangeOverride(SizeF)
Arranges the RadElement to its final location. The element must call the Arrange method of each of its children.
Declaration
protected override SizeF ArrangeOverride(SizeF finalSize)Parameters
finalSize
The size that is available for element.
Returns
The rectangle occupied by the element. Usually finalSize. Should you return different size, the Layout system will restart measuring and rearranging the items. That could lead to infinite recursion.
Overrides
Remarks
In this method call to the Arrange method of each child must be made.
CreateChildElements()
Called by the element when constructed. Allows inheritors to build the element tree.
Declaration
protected override void CreateChildElements()Overrides
Detach()
Uninitializes the associated instance of the GridViewTemplate in ColumnChooserElement.
Declaration
public void Detach()Implements
DisposeManagedResources()
Disposes the managed resources.
Declaration
protected override void DisposeManagedResources()Overrides
GetService<T>()
Retrieves currently registered RadService by the specified type.
Declaration
public T GetService<T>() where T : RadServiceReturns
T
Implements
Initialize(RadGridViewElement, GridViewInfo)
Initializes ColumnChooserElement with new instance of the GridViewTemplate.
Declaration
public void Initialize(RadGridViewElement rootElement, GridViewInfo viewInfo)Parameters
rootElement
An instance of the RadGridViewElement.
viewInfo
Implements
InitializeFields()
Initializes the fields.
Declaration
protected override void InitializeFields()Overrides
MeasureOverride(SizeF)
Measures the space required by the RadElement Used by the layout system.
Declaration
protected override SizeF MeasureOverride(SizeF availableSize)Parameters
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
Remarks
In this method call to the Measure method of each child must be made.

dropLocation
dragObject
Overrides
ProcessDragOver(Point, ISupportDrag)
Determines whether the element may be treated as a drop target during drag-and-drop operation.
