How to remove the ribbon from C1FlexViewer
C1FlexViewer control is used to preview report files and PDF files. To have the viewer control without a ribbon, you can use any of the following two ways:
1. Set the Minimized property of the Ribbon to True, as follows:
c1FlexViewer1.Ribbon.Minimized = true;
2. Note that C1FlexViewer is made up of the pane (for viewing the document) and the ribbon. So, to avoid having the ribbon, you can use the C1FlexViewerPane control itself. It can be dragged and dropped from the toolbox, instead of using C1FlexViewer.
