Issues that this update resolves

Issue 1 Consider the following scenario:

• You use a browser which can’t be recognized by ASP.NET, such as Amazon Kindle Fire 2 or Internet Explorer 11, to access an ASP.NET-based webpage.

• You trigger a postback event on that webpage.

In this scenario, the postback operation fails, and you receive the following error message:

Issue 2 Consider the following scenario:

• An ASP.NET website renders different content based on the user browser.

• A user uses Internet Explorer 11 to visit this ASP.NET website.

In this scenario, ASP.NET cannot recognize Internet Explorer 11 and will not render the content correctly. After the user applies this hotfix, Internet Explorer 11 can be recognized as InternetExplorer by ASP.NET.

Issue 3 Consider the following scenario:

• An ASP.NET page contains an update panel, and inside it there is an ImageButton. If a user clicks ImageButton, it will trigger a partial postback event and the server side click event.

• A user uses Internet Explorer 10 or a later version to access this ASP.NET page, and then clicks the Imagebutton.

In this scenario, the partial postback fails, and the server side click event is not fired.

Issue 4

Consider the following scenario:

• There is an ASP.NET page that contains a menu control.

• A user uses Internet Explorer 11 to access that page, and presses Tab to switch the focus between the menu control and other controls.

In this scenario, the user will receive the following JavaScript error message:

Note 1 There is a configuration switch to be used to revert back to the old behavior: <appSettings>
<add key="aspnet:UseLegacyBrowserCaps" value="true" />
</appSettings>
