There may be cases where you want to customize the **Submit** button behaviour, for example to add custom validation. To do this:

1. In the page’s **OnPreLoad** event, specify that WorkflowGen is NOT to handle the submit:

2. While this prevents WorkflowGen from initializing the **ValidationGroup** property of the **Submit** button, the workaround is to initialize it manually in the same page event. The default value is “WFGENPage”:

3. Create a custom method to assign to the button in the **OnPreLoad** event.

**Note:** Make sure to call the web form’s **base.OnPreLoad()** event, which is managed by [WorkflowGen.My](http://WorkflowGen.My).
