Hi Hamdi Boyaci,
At present we do not have support
for “Thumbnail view” in SfPdfViewer. We do not have any immediate plans
to implement this feature. At the planning stage for every release cycle, we
review all open features and identify features for implementation based on
specific parameters including product vision, technological feasibility, and
customer interest. The status of the feature can be tracked through the
following link,
