<Parameter>
Public Property ParametersReset As String

Property Value

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

Remarks

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

The handler function receives two parameters - the first parameter is the client-side Document Viewer (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_ViewerCustomization.js

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

_Host.cshtml

<script src="~/js/reporting_ViewerCustomization.js"></script>

Viewer.razor

<DxDocumentViewer ReportName="SampleReport" Height="1000px" Width="100%">
    <DxDocumentViewerCallbacks ParametersReset="ReportingViewerCustomization.onParametersReset" />
</DxDocumentViewer>
