In previous articles we have already reviewed the Stimulsoft Reports component, enabling you to perform certain actions with reports directly in the Internet. Undoubtedly, StiWebViewer is very simple and easy to use; however, it is slightly limited in some of the features. Of course, its functionality is more than enough for everyone, but if you want more, then ..., for such people, Stimulsoft Company provides a special component StiWebViewerFx.

To find StiWebViewerFx do not make any unnecessary body movements. The StiWebViewerFx component is delivered as a part of Stimulsoft Reports.Web and Stimulsoft Reports.Ultimate.

As it has become clear, it is used to display reports in a web browser. In this article we will examine how to work with the StiWebViewerFx component. Let’s get started:

First, consider what should be done for further displaying reports.

To make your report "beaming" in the Internet space, you should do the following:

1) Put the component in an HTML web page code.

webviewer in visual studio

2) Use the following code to load the report in the web Viewer:

C#

StiReport report = new StiReport();
report.Load("report.mrt");
StiWebViewerFx1.Report = report;

VB

Dim Report As StiReport = New StiReport()
Report.Load("report.mrt")
StiWebViewerFx1.Report = Report

After the viewer is loaded, the report is loaded using the OnGetReport event. This event, after subscribing to it, will occur every time when a viewer will need a report.

Below is a sample code using the OnGetReport event:

protected void StiWebViewerFx1_GetReport(object sender, StiWebViewerFx.StiOnGetReportEventArgs e)
{
    StiReport report = new StiReport();
    report.Load("D:\\SimpleList.mrt");
    e.Report = report;
}

The StiWebViewerFx component contains many pleasant and easy-to-use features. For example, the component automatically renders a report, even if it had not been rendered before being displayed.

If you want to appear WebViewerFx the entire area of the browser window, you should use the following code:

StiReport report = new StiReport();
report.Load("report.mrt");
StiWebViewerFx1.View(report);

Using this example, you will get displaying the report viewer to the entire area of the browser window. The items, located on the aspx page, will not be displayed.
