A control that is used to publish (preview, print and export) documents in ASP.NET applications and supports HTML5/JS technology.
[ToolboxBitmap(typeof(ResFinder), "Bitmaps256.ASPxDocumentViewer.bmp")] [ToolboxTabName("DX.18.2: Reporting")] public class ASPxWebDocumentViewer : ASPxWebClientUIControl, IControlDesigner
<ToolboxBitmap(GetType(ResFinder), "Bitmaps256.ASPxDocumentViewer.bmp")> <ToolboxTabName("DX.18.2: Reporting")> Public Class ASPxWebDocumentViewer Inherits ASPxWebClientUIControl Implements IControlDesigner
The HTML5 Document Viewer includes the following main features:
To add a Web Document Viewer to your application, do the following:
In the application's Web.config file, add the "resources" section as shown below.
<devExpress> <!-- ... --> <resources> <add type="ThirdParty" /> <add type="DevExtreme" /> </resources> </devExpress>
Alternatively, to avoid automatic loading of any libraries by a control (e.g., when such libraries are already referenced on the web page), declare an empty "resources" section and manually attach DevExtreme resources and the required third-party libraries (such as jQuery and Globalize) to the web page.
Deleting the DevExpress "resources" section from the Web.config file will enable the default behavior (with automatic loading only of DevExtreme, without adding third-party libraries).
To learn more about this configuration, see Embedding Third-Party Libraries.
To use the Document Viewer on mobile devices, enable the ASPxWebDocumentViewer.MobileMode property.
For the Mobile Viewer to properly render document pages in a mobile browser, include the viewport <meta> tag to your HTML file inside the <head> block as shown below.
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=0" />
To learn more about this mode, see Mobile Mode.
