Invalidate Method (AnnEditDesigner)

public override void Invalidate( 
   LeadRectD rc
)

 function Leadtools.Annotations.Designers.AnnEditDesigner.Invalidate( 
   rc 
)

Parameters

rc

The region to invalidate. If the value of this parameter is LeadRectD.Empty, then the entire surface is invalidated.

If the various derived designers determine that the surface of the container needs repainting they call the Invalidate method to perform the repaint. In turn, the Invalidate determines whether there is a valid object in the AutomationControl and calls its Leadtools.Annotations.Core.IAnnAutomationControl.AutomationInvalidate(Leadtools.LeadRectD) method.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
