Viewer Settings

The HTML5 Viewer is configured using properties that are located in the StiMvcViewerOptions class. All properties are divided into groups. Some of the groups contain subgroups for ease of use. The following is an example of setting the properties of the viewer.

Index.cshtml

...
@Html.Stimulsoft().StiMvcViewer("MvcViewer1", 
    new StiMvcViewerOptions() {
        Theme = StiViewerTheme.Office2022WhiteTeal,
        Localization = "~/Content/Localization/en.xml",
        Actions =
        {
            GetReport = "GetReport",
            ViewerEvent = "ViewerEvent"
        },
        Appearance =
        {
            InterfaceType = StiInterfaceType.Auto,
            ScrollbarsMode = true,
            ShowTooltips = false
        },
        Exports =
        {
            DefaultSettings = 
            {
                ExportToPdf = 
                {
                    CreatorString = "Company Name",
                    ImageQuality = 0.75f
                }
            },
            ShowExportToDbf = false,
            ShowExportToDif = false   
        }
})
...

Please note that all dashboard elements have their own save options and full-screen buttons for preview. There are no special options to control displaying them, but they can be disabled through the properties of the element. The code below should be added after loading the report before passing it to the viewer.

Default.aspx.cs

...
var dbsElementInteraction = (report.GetComponentByName("RegionMap1") as Stimulsoft.Report.Dashboard.IStiElementInteraction).DashboardInteraction;
(dbsElementInteraction as Stimulsoft.Report.Dashboard.IStiInteractionLayout).ShowFullScreenButton = false;
(dbsElementInteraction as Stimulsoft.Report.Dashboard.IStiInteractionLayout).ShowSaveButton = false;
