Helpers for ASP.NET MVC

This package is deprecated and no longer maintained.

The Helpers for ASP.NET MVC package contains helper classes and resources to simplify the implementation of common scenarios for providing a controlled printing experience within an ASP.NET MVC application/site:

  • Installation of the ScriptX add‑on on the client PC by a sample controller and view page crafted to assist the user during the installation process with prompts and screen snips depending upon the version of Internet Explorer being used.
  • Initialising print settings such as headers, footers, margins and the printer to use.
  • Buttons to initiate printing.

Printing with Client-side ScriptX is entirely a client PC process and so the ScriptX helpers all emit HTML, javascript and client event handlers that are executed on the client PC. There is never a call back to the server (action execution).

This package is dependent upon the following packages:

There are no dependencies on any particular client-side framework such as jQuery or Angular. The helpers output script in the global client-side namespace with all function names starting with ‘MeadCo_’. There are very few functions (one or two) and so there is little if any difference to wrapping the functions in a client-side namespace.

All of the server controls are provided in the namespace MeadCo.ScriptXClient:

The following controls are provided:

  • ClientPrinting
  • PrintButton
  • PrintPreviewButton

Using licensed features

Some features requires an Advanced printing publishing license.

To enable the licensed features, specify your license in the installers config section. For example, to use the evaluation license, edit the config section to include the evaluation license. The section will look like this: 


    <meadco>
        <scriptx>
            <clientinstaller filename="~/content/meadco.scriptx/installers/smsx.cab"
                             version="8,3,0,4" installhelper="~/ScriptXClientPrinting/Install" />
            <license guid="{8f351de0-5990-45c3-8fd2-8037b878939f}"
                     revision="0"
                     filename="http://licenses.meadroid.com/download/{8f351de0-5990-45c3-8fd2-8037b878939f}/mlf" />
        </scriptx>
    </meadco>
Initialising printing at the client with MeadCo.ScriptX.ClientPrinting

Initialising printing at the client requires:

  • The ScriptX add‑on ‘factory’ object
  • Some javascript to set the required print parameters

The section ‘Basic printing with ScriptX’ illustrates how to do this and while not at all difficult there are tedious aspects such as neatly handling the case of the add‑on needing to be installed.

The MeadCo.ScriptX.ClientPrinting helper simplifies the coding to using an intuitive set of classes: 


@ClientPrinting.GetHtml(printSettings: new PrintSettings()
{
    Footer = "Hello there from ScriptX MVC: &p of &P",
    Header = "ScriptX Demonstration page printed on: &D".
    PageSetup = new PrintSettings.PaperSetup()
    {
        Orientation = PrintSettings.Orientation.Landscape,
        Margins = new PrintSettings.PrintMargins()
        {
            Left = "1",
            Right = "1"
        }
    }
},clientValidationAction:ClientPrinting.ValidationAction.Redirect)
class MeadCo.ScriptXClient.ClientPrinting

This class provides instance and static methods GetHtml() that return the required html and scripting to declare the MeadCo ScriptX objects on the page (the MeadCo Secruty Manager object will be included if a license is described in web.config).

A view may call the static method as illustrated above. Alternatively a controller may create an instance of the class and set properties with the instance then passed to the view via one of the standard mechanisms (ViewBag, View Model etc) and then the view calls GetHtml() on the instance.

For example, a controller action may use this code before calling the view: 


    ClientPrinting p = new ClientPrinting() {
        PrintSettings =
        {
            Header = "Report: &D",
            Footer = "Page &p of &P",
        }
    };

    p.PrintSettings.PageSetup = new PrintSettings.PaperSetup()
    {
        Orientation = PrintSettings.Orientation.Landscape
    };

    p.ClientValidate = ClientPrinting.ValidationAction.None;
    p.HtmlPrintProcessor = ClientPrinting.ScriptXHtmlPrintProcessors.Default;
    p.InstallHelperUrl = @Url.Action("InstallScriptX", "Home");
    ViewBag.ScriptXClient = p;

and then the view may call: 


    @((ClientPrinting)ViewBag.ScriptXClient).GetHtml()

Methods Description
public static HtmlString GetHtml() Returns the HTML markup for the required objects and script to initialise the ScriptX on the client as determined from the arguments.
public HtmlString GetHtml() Returns the HTML markup for the required objects and script to initialise the ScriptX on the client as determined from the instance properties.

Properties Description Default
ValidationAction ClientValidate Specifies whether the ScriptX add‑on is to be installed if the required version isn't already installed. If the value is ‘redirect’ then if the required version is not available the user will be redirected to the installer page. ValidationAction.None - no scripted check is made that ScriptX is available. Internet Explorer will prompt to install the add‑on if it is not installed or a newer version is required.
string InstallHelperUrl The URL to redirect to when ClientValidate is ‘redirect’ and if the required version of ScriptX is not installed on the client PC The value of the installhelper attribute of the clientinstaller configuration element
ScriptXHtmlPrintProcessors HtmlPrintProcessor The HTML template to use. May be one of the values Default, Classic, IE7, IE 5, MaxiPT. This attribute specifies the value of the ScriptX templateUrl property ScriptXHtmlPrintProcessors.Default
PrintSetttings PrintSettings Describes the requires print settings such as header and footer, printer to use and orientation No settings
class PrintSettings

Describes common settings to apply to the print.

Properties Description Default
string Footer The footer text to use. See the footer reference for details. The user's IE default.
string Header The header text to use. See the header reference for details. The user's IE default.
string HeaderFooterFont A description of the font to use. The ScriptX reference for headerFooterFont gives full details. The user's IE default.
string Printer The printer to use. A publishing license is required to use this attribute. The user's default printer
PaperSetup PageSetup Describes the paper to use for the print The default for the user's default printer.

PrintMargins Margins The margins to apply. The user's default.
class PrintMargins

Describes the print margins to use. All margins are in the units specified in the parent PaperSetup class instance, or the users' default. Note that no margin value can be less than the printer's unprintable margin.

Attribute Description Default
string Left The left margin value in the specified units. The user's IE default.
