This is not so easy because you neet not only to refresh the web page but also a status variables. To update variables value a model must be executed. The problem is that most models in forms are executed in isolated data context what makes impossible to change outer variables state.
To control cyclic page refreshing you can use Page Refresh Check Component - essencial is not to exceed executionTimeout for a request set in IIS config.
To control variables state you can use some kind of external storage for variables (native message exchange, data base etec.). Also a good idea seems to be using a web session data - suitable components are provided.
So my idea (not tested ) is:
- Use Page Refresh Check for cyclic page refreshing and updating externally stored statuses.
- Show current statuses in grid populated with values from externally stored data.
