PdfWebControl.RenderThumbnailsOnDemand Property

public bool RenderThumbnailsOnDemand { get; set; }

Public Property RenderThumbnailsOnDemand As Boolean
	Get
	Set

Property Value

To have an effect, this property must be set before CreateDocument(String,Byte[]) is called.

This property will be ignored if AllowFindMatchingPdf is true and the PDF referenced by CreateDocument(String,Byte[]) was previously loaded. (The value of this property when the PDF was originally loaded by CreateDocument(String,Byte[]) will instead be used)

This property will be ignored if GroupThumbnails is false or RenderOnDemand is false. At this time, only grouped thumbnails can be rendered on demand.

RAD PDF prior to version 2.31 did not support this feature. All documents created with version 2.30 and earlier will behave as if this property is false.
