Note: There is one more issue to highlight. Using reflection, one can add custom renderer to reportViewer. Why not take word renderer from ssrs 2008? The answer is - the interfaces are incompatible. And yes, i learned it the hard way. Localization to localize reportViewer gui interface one must implement ireportViewerMessages and assign an instance to messages property.

Export to microsoft Word Articles 3 and 4 tell us how to extend render capabilities of a reportViwer. In short - there is render to html but it is off and it is hard-coded. To change the situation, one must change renderingExtensions. RenderingExtensions stRenderingExtensions( ) Each extension contains self explanatory fields: Name - internal name of a rendering extension m_localizedName - localized name that is shown in Export dropdown m_isVisible, m_isExposedExternally - visibility and availability to the end user But all mentioned code is not public.

Null, "Data source must be defined" return new ReportDatasource( name, value where reportName( ) is: public static string toreportName( this Type type ) var isTypedDataTable nested artsWith( "System.
