Invalidate Method (AnnDesigner)

The region to invalidate. If the value of this parameter is LeadRectD.Empty, then the entire surface is invalidated.
Manually invalidates this designer.
Syntax
 function Leadtools.Annotations.Designers.AnnDesigner.invalidate( 
   rc 
)

Parameters

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

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