PdfWebControlRenderThumbnailsOnDemand Property

Gets or sets a value indicating whether the server should render PDF thumbnails as they are needed by PdfWebControl instances.

Namespace:  RadPdf.Web.UI
Assembly:  RadPdf (in RadPdf.dll) Version: 3.48.0.0 (3.48.0.0)
Syntax
Copy
public bool RenderThumbnailsOnDemand { get; set; }

Property Value

Type: Boolean
If true the server should render PDF thumbnails on demand; otherwise, if false the server will render all thumbnails upfront in order. The default value is true.
Remarks

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.
