RunState transition
Transitioning to Running
When an item is started, the RunState property for that item changes to Running, unless an error occurs during the start process, in which case it reverts to Stopped.
Child items of the parent item that starts are also started. The items start in order, from top to bottom of the Project Explorer hierarchy, from the parent item, one branch at a time, until every child item is started.

Transitioning to Stopped
When an item is stopped, the RunState property for that item changes to Stopped, even if an error occurs during the stop process.
Child items of the parent item that stops are also stopped. The items stop in order, from top to bottom of theProject Explorer hierarchy, from the parent item, one branch at a time, until every child item is stopped.

ChangeState property
Every item has a ChangeState property that indicates whether a property value has changed since the last time the project was saved to the server database. If this property is not immediately visible, on the Tools menu, select Options, and then select the Show advanced configuration features check box.

Possible ChangeState property values are:
|
Status |
Description |
|---|---|
|

|
Modified |
Modified and not saved. |
|
Unchanged |

Notes:
New or modified items in Studio appear blue in the Project Explorer hierarchy until
saved.
Modified items that have their RunState property set to Running do not update their values until the modification is saved.
