How To Debug WebParts in VS 2008

If we need to debug a WebPart which is being integrated into Sharepoint Website then have to modify the existing values in web.config as below :

<customErrors mode=“Off” />

<compilation batch=”false” debug=”true“>

Once the web.config is updated then you can directly set a breakpoint in your webpart source code and can debug in a Visual Studio environment.

1. Open your web part solution in VS 2008
2. Open Moss site or Web part page in a IE (Web Browser)
3. Place a Breakpoint in your code
4. Select Attach to Process from the DEBUG menu from the VS.
5. From the available process list select “w3wp.exe” & click on attached button.
