In Visual Studio 2008, you can set a breakpoint in a server-side file. At run time, the breakpoint is automatically mapped to a breakpoint at the corresponding location in the client-side file.

Breakpoint mapping is subject to certain limitations. For more information, see Limitations on Script Debugging.


Client-side breakpoints persist across debugging sessions, even if you close Visual Studio.

To set a breakpoint in a script file

  1. Open the server-side script file.

  2. On the line where you want to set the breakpoint:

    • Click the gutter on the left side of the source window, or

    • Right-click the line.

  3. Point to Breakpoint, and then click Insert Breakpoint.

    If you are in debug mode or break mode, the breakpoint is immediately mapped to the client-side file. If you are in design mode, the breakpoint is mapped when you start debugging.

To open a server-side script file

  1. In Solution Explorer, open the <Website Pathname> node.

  2. Double-click the script file that you want to view.

    The server-side script file opens in a source window.
