Silverlight & Javascript Communication (Part 1)

Call Javascript Methods from within Silverlight

(http://pietschsoft.com/post/2008/06/Silverlight-and-JavaScript-Interop-Basics.aspx)

Using the Eval method (vulnerable to script injection)

using System.Windows.Browser; HtmlPage.Window.Eval("myJSObject = 2;"); // set global parameter HtmlPage.Window.Eval("myJSMethod();");

Using the Invoke method

using System.Windows.Browser; HtmlPage.Window.Invoke("myJSMethod"); // no arguments HtmlPage.Window.Invoke("myJSMethod", "Chris", 42); // pass in 2 args

Return values from Javascript method calls to Silverlight

// Returning a Double double doubleValue = (double)HtmlPage.Window.Invoke("myJSMethod"); // Returning a String string stringValue = (string)HtmlPage.Window.Invoke("myJSMethod");
