Returns

Type	Description
TBuilder	The WebDocumentViewerClientSideEventsBuilderBase<TBuilder, TEvents> object that can be used for method chaining.

Remarks

The ParametersReset event is raised when the user clicks the Reset button in the Preview Parameters panel. The ResetParameters method also raises the ParametersReset event.

The event handler function receives the following parameters:

• Event sender (the client Document Viewer object that exposes the IPreviewModel interface)
• An object that exposes two properties:
  • ParametersViewModel
    A View Model for report parameters.
  • Parameters
    Report parameters whose values were reset.

The following code snippet collapses the Parameters panel after parameter values are reset:

ASP.NET Core

<script type="text/javascript" id="script"> 
    function parametersReset(s, e) {
        var preview = s.GetPreviewModel();
        if (preview) {
            preview.tabPanel.collapsed = true;
        }
    }
</script>
