    Public Properties
     NameDescription
    Public PropertyGets the RenderInputButton object representing the accept button in the current document (the first RenderInputButton object with RenderInputButton.AcceptButton property set to true).  
    Public PropertyGets the actual measurement device which was used to generate the document. This device can differ from the one specified by CreationDevice, for example if CreationDevice was set to MeasurementDeviceEnum.Printer but the current system has no printers installed.  
    Public PropertyGets the name of the actual measurement printer which was used to generate the document. This can differ from the name specified by CreationPrinterName, for example if the report was rendered on a system with no such printer.  
    Public PropertyGets or sets a value indicating whether to add messages to the current document's Warnings collection when script errors are found.

    The default value is false.

     
    Public PropertyGets or sets a value indicating whether methods can be called on the current document that would result in the document becoming non-reflowable (such as NewPage). If this property is false, calling such methods throws an exception. If this property is true, calling such methods sets the Reflowable flag to false on the current document.

    The default value is false.

     
    Public Propertystatic (Shared in Visual Basic)Gets the version of C1PrintDocument assembly.  
    Public Property

    This property is obsolete.

    Public PropertyGets the effective layout for the current page. That layout is automatically built on the fly by merging all applicable layouts defined for the current document in PageLayouts. You may change the properties on CurrentPageLayout programmatically. The changes will be effective immediately if they are made in the PageConfigure event handler, otherwise they will take effect for the next added page.

    Note that this property is only available during document generation, at other times null is returned.

     
    Public PropertyGets the C1.C1Preview.DataBinding.C1DataSchema object representing the data schema built into the current document.

    Public Propertystatic (Shared in Visual Basic)Gets a string representing the version of the document persistence format supported by the current assembly. This version is used to check persisted documents' compatibility. Versions are backwards-compatible, but not vice versa (i.e. a document persisted using a newer version of C1PrintDocument may be unreadable by an older version).  
    Public PropertyGets or sets the DocumentInfo object containing the information about the current document (such as author, company, and so on).  
    Public PropertyGets or sets the script that is executed when the current document starts generating.
