To build a loaded report, you need to call the render() function on the StiReport report object. For example, you need to build a report before exporting it:

 

app.py

 

from stimulsoft_reports.report import StiReport

from stimulsoft_reports.report.enums import StiExportFormat

 

report = StiReport()

report.loadFile(url_for('static', filename='reports/SimpleList.mrt'))

report.render()

report.exportDocument(StiExportFormat.PDF)

 

 

 

The full example code is available on GitHub.

 

If it is necessary to perform any actions with the report before it is rendered using JavaScript code, simply define the name of the JavaScript function for the onBeforeRender event. The function will receive the action type and the report itself as arguments. Example of registering JSON data before the report is rendered:

 

app.py

 

from stimulsoft_reports.report import StiReport

 

report = StiReport()

report.onBeforeRender += 'beforeRender'

report.loadFile(url_for('static', filename='reports/SimpleList.mrt'))

report.render()

 

 

render.html

 

<script>

function onBeforeRender(args) {

var dataSet = new Stimulsoft.System.Data.DataSet("SimpleDataSet");

dataSet.readJsonFile("Demo.json");

 

var report = args.report;

report.regData(dataSet.dataSetName, "", dataSet);

}

</script>

 

 

 

To perform any actions after the report has been rendered using JavaScript code, simply define the name of the JavaScript function for the onAfterRender event. The function will receive the action type and the report itself as arguments. Example of displaying a message after the report is rendered:

 

app.py

 

from stimulsoft_reports.report import StiReport

 

report = StiReport()

report.onAfterRender += 'afterRender'

report.loadFile(url_for('static', filename='reports/SimpleList.mrt'))

report.render()

 

 

render.html

 

<script>

function afterRender(args) {

alert("The report rendering is completed.");

}

</script>
