Methods

AnalyzeQueue(List<GridViewEvent>)

Declaration
public bool AnalyzeQueue(List<GridViewEvent> events)
Parameters
System.Collections.Generic.List<GridViewEvent> events

Returns
System.Boolean

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
System.Drawing.SizeF finalSize

The size that is available for element.
Returns
System.Drawing.SizeF

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 : RadService
Returns
T

Type Parameters
T

A type derived from RadService
Implements

Initialize(RadGridViewElement, GridViewInfo)
