This sample project shows how to change the Report Viewer configuration. You just need to set the desired option of the Viewer to true if you want to display a certain control. Set the desired option of the Viewer to false if you want to hide a certain control. For example, PreviewControl.ShowBookmarksPanel = cbBookmarks.Checked means that the bookmarks will be enabled or disabled depending on the value of the checkbox.

This code shows only some options, all options you can see in the downloaded sample project

private void cbBookmarks_CheckedChanged(object sender, System.EventArgs e){
