I don't know what you are your requirements but it doesn't seem reasonable to me. Looks like a nice way to shoot yourself in the foot.

WebApplication.TryLock is not what you think it is. It is a low level locking mechanism that is not related to what happens on the browser side.

If your datamodule creation is triggered by a control action on the browser, possibly in an async event, use the LockOnAsyncEvents property of the control. It will bring the locker to the foreground and make it visible while the action is being processed. It's is simple and requires no code

If the datamodule creation is not triggered by a control action, you don't need nor should give any visual feedback (like putting a lock on the user browser screen)
