In your CSHTML5 project, create a new C# class and write the " Interop.LoadJavaScriptFile()" code that will load the JS file.

You can either point to an online location where those JS files are hosted (such as those referenced on CDN JS) or you can download the JS files and add them to your CSHTML5 project.

To create such a wrapper, follow these steps: It encapsulates all the interop between JS and C# so that the rest of the application can interact with the JavaScript library using only pure C# code.

How to create C#/XAML-based wrappers around JS librariesĪ C#/XAML-based wrapper around a JavaScript library is useful because it allows the person who uses the wrapper to consume the JavaScript library in pure C# and XAML, without ever having to write any JavaScript code.įor example, the ZIP Compression extension is a C#-based wrapper around the JSZip JavaScript library.

This approach works best with simple XAML elements, such as Border or Canvas.Īlternatively, you can use the HtmlPresenter control to put arbitrary HTML/CSS code in your XAML, and then read the ".DomElement" property of the HtmlPresenter control to get a reference to the instantiated DOM element in order to pass it to the JavaScript library. To ensure that it is in the Visual Tree, you can read the IsLoaded property, or you can place your code in the "Loaded" event handler. For this method to succeed, the XAML element must be in the Visual Tree. GetDiv(FrameworkElement) in order to get the DIV associated to a XAML element. In other words, the first argument of the "ExecuteJavaScript" method must be a string literal.įor example, the following code will NOT work:Ĭ( "alert('" + messageToDisplay + "')") ĬSHTML5.Interop or another DOM element in order to render stuff. } IMPORTANT: creating JavaScript code by concatenating strings such as in "alert(" + messageToDisplay + ")" or by using String.Format will NOT work, because the JavaScript code needs to exist at compile-time rather than at runtime. Here is an example: void DisplayAMessage( string messageToDisplay)Ĭ( "alert($0)", messageToDisplay) You can pass C# variables to your JavaScript code by passing them as additional arguments to the "Interop.ExecuteJavaScript" method, and using the placeholders $0, $1, $2.The following C# example shows how to retrieve the current Width of the browser window by reading the JavaScript "screen.width" property: double screenWidth = Convert.ToDouble( ( "screen.width")).Gets compiled into the following JavaScript code: alert( 'The current URL is: ' + location.toString()) MessageBox.Show( "The current URL is: " + ( "location.toString()")) Such JavaScript code is copied "as is" when the project is compiled. If you want, you can place JavaScript code directly inside your C# code by calling the "Interop.ExecuteJavaScript" method.When you compile the project, your C#/XAML code gets automatically compiled into JavaScript and HTML.
