TdxPDFViewerOptionsBehavior.RenderContentDelay Property

Specifies the time interval (in milliseconds) between the latest change made to the document view and the subsequent update that reflects the change.

Declaration

property RenderContentDelay: Integer read; write; default dxPDFDocumentViewerDefaultRenderContentDelay;

Property Value

Type	Default
Integer	dxPDFDocumentViewerDefaultRenderContentDelay

Remarks

The PDF Viewer control delays updating the displayed document pages in response to rotation, scrolling or zooming operations to improve end-user experience by avoiding excessive repaint operations. Each two document view changes made within the time interval specified by the RenderContentDelay property are considered a single change requiring only a single update.

To improve the application UI’s responsiveness when the PDF Viewer control displays multiple document pages simultaneously, you can increase the RenderContentDelay property value and/or set the RenderContentInBackground property to True to enable asynchronous page rendering.

Note

A newly assigned RenderContentDelay property value is automatically clamped within the range between 50 and 1000, inclusive.

The default RenderContentDelay property value is dxPDFDocumentViewerDefaultRenderContentDelay.
