    Assembly: DevExpress.Blazor.Reporting.v25.1.JSBasedControls.Common.dll

    NuGet Package: DevExpress.Blazor.Reporting.JSBasedControls.Common

    Declaration

    public string PreviewDocumentReady { get; set; }

    Property Value

    Type Description
    String

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

    Remarks

    The DocumentReady event occurs before the Report Designer Preview loads a document.

    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:

    • ReportId
      The report ID.

    • DocumentId
      The ID of the document that is ready to be displayed in the Report Designer Preview.

    • PageCount
      The total number of pages in a document.

    The following code causes the Preview to flip through document pages:

    window.ReportingDesignerCustomization = {
        onPreviewDocumentReady: function (s, e) {
            var previewModel = s.GetPreviewModel();
            var goToNextPage = function () {
                var pageIndex = previewModel.GetCurrentPageIndex();
                if (e.PageCount <= pageIndex)
                    return;
                previewModel.GoToPage(pageIndex + 1);
                setTimeout(function () { goToNextPage(); }, 3000);
            }
            goToNextPage();
        }
    }
