Add support for what export options are available through option dialogs¶

What is new - 24.0¶

The integration library contains three modules that can be used in a DataFlex application to let the end-user select an export of the report:

ExportReportDialog.wo (Web Desktop)
ExportReport.wo (Web Drilldown)
DRExportOptions.dg (Windows)

The options in the export choices pull-down can now be controlled by properties of the cDRReport object. The following properties are available:

Property	Windows	Notes	Web	Notes
pbShowExportToCSV
pbShowExportToHTML	Yes	-	Yes
pbShowExportToImage	Yes	-	-	Is controlled by export to GIF, JPEG, PNG, and TIFF
pbShowExportToPDF	Yes	-	Yes
pbShowExportToRTF	Yes	-	Yes
pbShowExportToXLS
pbShowExportToXLS
pbShowExportToTIFF
pbShowExportToJPEG
pbShowExportToPNG	-	Yes
pbShowExportToTIFF

The DRExportOptions.dg automatically reduces the number of options based on the properties.

The ExportReportDialog.wo and ExportReport.wo require sending CopyExportOptions prior to opening the modal dialog or view. The code for that is:

Send CopyExportOptions of oExportReportWebView (oReport)

This can be inserted in the OnClick (or any other) event that lets the user navigate to the export options page.

Example:

Object oExportReportMenuItem is a cWebMenuItem
    Set psCaption to "Export Results"
    Set psTooltip to "Select Export Options"
    Set peActionDisplay to adMenu

    WebRegisterPath ntNavigateForward oExportReportWebView

    Procedure OnClick
        Send CopyExportOptions of oExportReportWebView (oReport)
        Send NavigatePath
    End_Procedure

    Procedure OnNavigateBack Handle hoCallback tWebNavigateData NavigateData
        Send ExportReportToDownloadURL of oReport NavigateData.NamedValues
    End_Procedure
End_Object

And for the modal dialog:

Object oExportButton is a cWebButton
    Set psCaption to "Export Report"
    Set piColumnSpan to 3

    Procedure OnClick
        Send CopyExportOptions of oExportReportDialog (oReport)
        Send Popup of oExportReportDialog Self
    End_Procedure

    Procedure OnCloseModalDialog Handle hoModalDialog
        tWebNavigateData ExportOptions 

        Get ExportChoices of hoModalDialog to ExportOptions

        Send ExportReportToDownloadURL of oReport ExportOptions.NamedValues
    End_Procedure
End_Object
