How To Set Access Key For Web Server Controls

Access key combination allows users to press ALT key plus another key to focus or jump to a specific control.

Some controls have Access property where you can set this like TextBox or ListBox. As an alternative, you can set an Access key for a Label control and then tell the browser to associate it with another control. With this approach, you can use the Label control as caption to indicate the access key with an underlined letter.

To set the access key using label control you must:

1. Add the control to be associated
2. Add a Label control
3. Set the access key
4. Associate the control to receive focus

Here's an example:

<asp:Label ID="lblLastName" runat="server"
Text="<u>L</u>ast name: ">
<asp:TextBox ID="txtLastName" runat="server"></asp:TextBox>

Note that setting focus by using access key from a Label control requires that client scripting is enabled in the browser.
