HttpCapabilitiesBase.SupportsAccesskeyAttribute Property

Gets a value indicating whether the browser supports the ACCESSKEY attribute of HTML <a> (anchor) and <input> elements.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)
public virtual bool SupportsAccesskeyAttribute { get; }

Property Value

Type: System.Boolean
true if the browser supports the accesskey attribute of HTML <a> (anchor) and <input> elements; otherwise, false. The default is false.

The accesskey attribute extends control of forms and links on a Web page to mobile and accessible platforms by assigning a soft key or other controller on the device to interact with HTML <a> (anchor) and <input> elements.

The following code example shows how to determine whether the browser supports the accesskey attribute of HTML <a> (anchor) and <input> elements.

<script runat="server">
    void Page_Load(Object Sender, EventArgs e)
    {
        CheckBrowserCaps();
    }

    void CheckBrowserCaps()
    {
        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).SupportsAccesskeyAttribute)
        {
            labelText = "Browser supports the ACCESSKEY attribute of HTML A(anchor) and INPUT elements.";
        }
        else
        {
            labelText = "Browser does not support the ACCESSKEY attribute of HTML A(anchor) and INPUT elements.";
        }

        Label1.Text = labelText;
    }
</script>
