EaxChartView.RequestMetadata

Syntax

RequestMetadata: function (sender, args);

Parameters

sender. Event source.

args. Event information.

Description

The RequestMetadata event is generated when no metadata is available in express report chart data source.

Example

Executing the example requires that the HTML page contains the ExpressBox component named expressBox (see the page Example of Creating the ExpressBox Component). Handle the RequestMetadata event:

// Get express report chart view
var chartView = expressBox.getDataView().getChartView();
// Handle the RequestMetadata event
chartView.RequestMetadata.add(function () {
    console.log("Metadata is requested.")
});
// Call the RequestMetadata event
chartView.RequestMetadata.fire(this);

After executing the example as the result of firing the RequestMetadata event the browser console displays a message that metadata is requested.
