Leveraging IE9 Capabilities in the .NET WebBrowser Control, Including SVG Support
.NET (3.5) WinForms applications often utilize the WebBrowser control. However, achieving full IE9 functionality requires understanding its inherent limitations.
The WebBrowser control defaults to the installed IE version but usually renders pages in IE7 Standards mode. To enable IE9 features, including SVG support, two primary methods exist:
HTML Meta Tag: Adding the meta tag <meta http-equiv="X-UA-Compatible" content="IE=9"> within the <head> section of your HTML page, before any other <link> or <script> tags, forces IE9 rendering mode.
Registry Key Modification: Create or modify a registry entry at HKLMSOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_BROWSER_EMULATION. Add your application's executable name (e.g., myApplicationName.exe) with a value data of 9000 to force IE9 mode. Note that other values may also work. Alternatively, creating this key under HKCU instead of HKLM avoids requiring administrator privileges.
By employing either of these techniques, developers can unlock the full potential of IE9 within their .NET WebBrowser controls.
