#Declaration

public ReportDesignerPreviewClientSideEventsBuilder ParametersReset(
    string callback
)

#Parameters

Name Type Description
callback String

The name of a JavaScript function or the entire JavaScript function code used to handle the ParametersReset event.

#Returns

Type Description
ReportDesignerPreviewClientSideEventsBuilder

A ReportDesignerPreviewClientSideEventsBuilder that can be used to further configure the Report Designer Preview Client Side Events.

#Remarks

The ParametersReset event fires each time report parameter values are reset (for instance, when an end-user presses the Reset button in the Parameters panel). When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientReportDesigner object. The second one is an object with the following structure.

  • ParametersViewModel
    A View Model for report parameters.

  • Parameters
    Report parameters whose values have been reset.

The code sample below demonstrates how to use this event to automatically collapse the Parameters panel after resetting parameter values.

@{
    var designer = Html.DevExpress().ReportDesigner("reportDesigner1").Height("1000px")
        .Bind(Model.Report)
        .DataSources(configureDS => { foreach (var ds in Model.DataSources) { configureDS.Add(ds.Key, ds.Value); } })
        .ClientSideEvents(configure => { configure.Preview(configure => { configure.ParametersReset("previewParametersReset"); }); } );
}
