Public Property PreviewParametersReset As String

Property Value

Type	Description
String	The name of a JavaScript function used to handle the PreviewParametersSubmitted event.

Remarks

The ParametersReset event fires each time report parameter values are reset (for instance, when a user clicks Reset in the Parameters panel).

The handler function receives two parameters - the first parameter is the client-side Preview (the event sender) and the second parameter is an object with the following properties and methods:

• ParametersViewModel
  A View Model for report parameters.

• Parameters
  Report parameters in which values are reset.

The following code demonstrates how to automatically collapse the Parameters panel after parameter values are reset:

reporting_DesignerCustomization.js

window.ReportingDesignerCustomization = {
    onPreviewParametersReset: function(s, e) {
        var preview = s.GetPreviewModel();
        if (preview) {
            preview.tabPanel.collapsed(true);
        }
    }
}
