GeometrySource.InvalidateGeometry Method

  • Article

Notifies that the geometry has been invalidated because of external changes.

Namespace: Microsoft.Expression.Media
Assembly: Microsoft.Expression.Drawing (in microsoft.expression.drawing.dll)

Syntax

'Declaration
Public Function InvalidateGeometry ( _
    reasons As InvalidateGeometryReasons _
) As Boolean

'Usage
Dim instance As GeometrySource(Of TParameters)
Dim reasons As InvalidateGeometryReasons
Dim returnValue As Boolean

returnValue = instance.InvalidateGeometry(reasons)

public bool InvalidateGeometry (
    InvalidateGeometryReasons reasons
)

public:
virtual bool InvalidateGeometry (
    InvalidateGeometryReasons reasons
) sealed

public final boolean InvalidateGeometry (
    InvalidateGeometryReasons reasons
)

public final function InvalidateGeometry (
    reasons : InvalidateGeometryReasons
) : boolean

Remarks

The geometry is typically invalidated when parameters are changed. If any geometry has been invalidated externally, the geometry will be recomputed regardless if the layout bounds change.
